  1. The situation is indeed alarming, fortunately the OP is not alone in their concerns and others have already begun ringing the alarm bells as you can see from this thread...

    Petition against new SL economy policy

    (of course that was from January 2005, but just because SLs final gasp has been going on for the last 15 years doesn't make the situation any less dire!)

    Seriously though, for anyone actually worried about the future of Second Life, I'd recommend heeding the words of one of the posters in that archived thread when he said

    Change is often met with fear, but this is all bordering on histrionics.

    thanks @Cristiano Midnight for the sage (and timeless) advice! ;)

    I keep hearing about "Local Textures" but I can't see the option in Firestorm, so yeah ... everything I make costs thousands in uploads.  😡

    Local textures are available in Firestorm, you simply need to open the texture picker in the build window and select the Local radio button (see image below). Once there you can add textures located on your hard drive and apply them to objects in world and every time the texture is changed locally (i.e. each time you save the texture in your bitmap editor and overwrite the original) the texture on the in world object updates almost instantaneously.

    This "retopo" thingie seems like a gross misuse of the real meaning of the word "topology" 

    It's basically a 3D term that's been shortened for expedience, but retopology literally means the rearranging of the topology or "layout" of the polygons that comprise a 3D model, (which is pretty much the dictionary definition of "topology")

    I will check out 3D coat for sure, but I'm betting it's Windows only? (because I haven't heard of it).

    3D Coat is available for Windows, Mac OS and Linux.  The reason you haven't heard of it is because while the creators of the app are great at making software, they really don't seem to have much of a clue when it comes to marketing, which is a shame since, in my opinion, it's one of the best pieces of 3D software available and is sold at a fraction of the price of other comparable 3D applications.

    I like to use vector based tools more than bitmap ones though

    3D Coat does have some vector based tools and several other resolution independent options that are quite useful when working with high/low rez textures.  It's well worth checking their youtube channels which contain a wealth of tutorial videos, they even have a feature in the app where hovering your mouse over certain tools and options and pressing F1 will automatically open a browser window to the appropriate youtube video tutorial for it.

    I'm just trying to texture it and at the same time understand what's wrong with it so that when I am trying to make my own mesh I don't make the same mistakes.

    A commendable goal, and one which other would-be creators should take note of and learn from, SL content would be all the better for it if they did!

    I was actually hoping to see a more "tangled" result.  What I'm trying to get at is what *causes* it, so I guess the answer is ... 

    "not remapping the UV before upload"? 

    Yes, that seems the most likely explanation.

    There are two fairly simple solutions to your problem, the simplest of which is one you've already discovered i.e. just avoid applying the texture to that area and have the edges of the texture end just before the deformation of the UV begins.  The alternative would be to take that same UV grid texture and add it as an underlying layer in your bitmap editor. Then, using the grid texture as a guide, you can distort your texture so that it matches the distortion of the UV map you're seeing in the last screenshot you posted (in this case it looks like stretching the lace pattern at the edge of the texture by around 250-300% would compensate for the UV map distortion).  As long as you're using the Local Textures feature this can be relatively quick and painless and will avoid having to re-upload the texture multiple times while fixing the issue.

    I'm still getting my head around "retopo" but I'm thinking this is something that could easily have been done in Blender *after* importing from Marvelous Designer.

    Since you stated in your OP that this is a full perm mesh that you purchased rather than one you created yourself I'm assuming you don't have access to the mesh outside of SL, so retopologizing isn't going to be an option in this instance, but if you plan on using Marvelous Designer in the future it's most definitely a process that you should try to familiarize yourself with.  Having a clean topology that follows the form of the object you're modelling not only makes UV mapping simpler but can also make rigging mesh objects far easier and more effective than trying to rig the mesh output you get from MD. 

    Personally I'd recommend taking a look at an app called 3D Coat, it's relatively inexpensive and there's a 30 day demo available so you can get a good idea of how it works before having to invest any money in it.  It has a lot of tools specifically designed for the purpose of retopology and UV mapping, as well as a really nice paint room that allows you to paint directly onto a 3D model on multiple channels simultaneously (i.e. diffuse/colour, normal/bump & specular/shiny, all the maps you need for materials in SL).  It's basically like a 3D Photoshop with Zbrush and retopology/UV mapping tools thrown in for good measure.

  5. Applying a UV grid texture (like the one below) can help you discern if the UV mapping is uniform across the entire mesh or if some areas have been squashed or distorted in some way.  That will give you some idea of the extent to which you'll need to distort your textures to fit the UV mapping of the mesh correctly when creating custom textures for it.

    As for deformations that occur due to the shape you're using try rezzing the mesh rather than wearing it, assuming the creator has uploaded it at the correct scale it should conform to the default shape used to create the mesh.

    As for reasons why this particular mesh is doing this, it's probably either because the creator didn't make the UV mapping uniform to begin with, or because they altered the mesh after applying UV mapping and in doing so compressed the UV, thereby causing the texture to become "squashed" on those polygons.

  6. Since texture animation works on all texture channels you can make some very nice running water effects using a  seamless fractal noise generator to create normal/specular maps & alpha channels, etc and tweaking the UV mapping on your mesh to control the speed/direction of the flow of the water.

    Let's face up to one unpleasant fact. Those of us that successfully sell "products" in SL are pretty good at peddling snake oil. We have to be in order to make a go of flogging the intangible for what is equivalent to real money, for all the legal nicety that the L$ is an "in-game token." I say this not as a criticism, but from the honesty born of having been moderately successful at doing it in the past. Most of us have encountered situations  where we can achieve the effect we want but our skills and knowledge are only up to doing it in a way that isn't "kind to the machine" and we are salesmen as much as we are artists so if we can talk that up into a feature rather than a detriment, we tend to do so. I know I was guilty of that on a couple of occasions. My knowledge and skills have improved since then and I'd hope I would not fall into that trap again but if all were being honest I think most would admit to at least a few instances of it in their history.

    And because we are good at peddling snake oil, folks buy into those sales pitches. You see it in software too, horrible kludges being marketed as a feature until even developers that know better have to hold their noses and implement it to stay competitive.

    You will never convince folks that have bought into it that way that it's bad so consumer choice will never fix this. That's why LL have to if it's ever going to change. They just don't think that the pain it will cause to the userbase is worth it, so they don't do it. They don't even incentivize merchants and creators to make improvements in this regard for new products, let alone update older ones. Without both the stick and the carrot, way too many of those merchants and creators just ain't gonna change what they are doing.

    All very valid points and I'd agree that the onus is on LL to fix the issues with the lack of incentivization for creating more efficient content (and conversely the lack of penalization for those creating poorly optimized content).

    That being said the fact that SL content creators are, as you put it, so "good at peddling snake oil" and are often looked upon by their customers (and SL residents in general) as experts in content creation, I believe they do share some responsibility when it comes to the information (and sometimes disinformation) that they disseminate.

    A large part of the process of improving the optimization of content uploaded to SL is going to involve providing residents with much better information on the best (and worst) practices involved in content creation, and the difficulty in doing that will depend a lot on how many differing opinions users are exposed to.  If LL are saying one thing and various content creators are saying something completely different, it's just going to lead to confusion and the propagation of more bad practices.

    Good idea, but I hate to sound like a vandal but since you ask... - I dragged the script out to halt it since it wouldn't shut off any other way, then I explored it by clicking all over & viewing transparent - found three transparent tails (that much was obvious before I wrecked it - they alternate on and off like traffic lights. Eventually these became visible when I saved it to inv and re-rezzed it.

    The fact that the additional tails only became visible after being taken into inventory then re-rezzed is curious, and lends credence to the theory that it's using texture animation somehow (since texture animation is an object property that persists after the script that initiated it is removed, but can be broken when taking the then unscripted object back to inventory and re-rezzing it).

    Sorry to ask a really obvious question but you do have "Select Faces" selected in the build window and you've selected the tail face and not the face that corresponds to the body rather than the tail right?  It's just the texture in the preview window doesn't look compatible with any type of texture animation and it's hard to imagine what method they could possibly be using to do alpha switching on the tail given what you're describing and the screenshot you posted.

    a 4-position tail only shows 1/16 of the texture at any time; for 10 positions only 1/100

    I'm not sure I follow your math here Qie, or maybe we're thinking of slightly different methods.  To illustrate here's an example tail alongside the uv layout and corresponding texture.

    tail-uv-example.thumb.JPG.6ee2e33f4ec45fdce682c8ce60bce22d.JPG

    As you can see each of the four tails use approximately 1/4 of the texture space (the other 3/4 being transparent).  Adding a texture animation with the PING_PONG flag set would cause the tail to appear to move from side to side as that opaque section of the texture lines up with the uv mapping for each segment.

    Of course the limitation of this method is that you have to use the same texture and uv island layout for all versions of the tail and only modify the vertex positions of the mesh rather than having individual textures and uv layout for each version of the tail.

    The mystery technique operates on a single mesh object (no linked parts) that reports only 2 faces.... all one body with several tail fins.... as at least three of the tails have the exact same face number.

    It's hard to say for certain without inspecting the object in question but the most likely explanation for what you describe is:

    The body is one material and has a regular texture on it.

    The tail(s) are all sharing the same material/texture, but have different uv mapping, with the UVs of each tail being located in a different quadrant/section of the texture map.

    The tail texture appears in only one section of the image, the rest of the texture is transparent, and the tail "animation" is achieved by changing the offsets of the texture on the tail(s) to change which one of them is currently visible (most likely with the use of llSetTextureAnim).

     

    It's a crude but reasonably effective way of simulating animation, but before you use this particular method I'd suggest taking a look at animesh.  It allows you to create far more realistic and efficient animated content than the various forms of "alpha swapping" that are currently in use.

    Hello,

      im 3dsmax 2019 user, and i have no idea how to create LOD file for my models , is there any advice or guidance please ?

    thanks

    The basic principle for creating LOD models is pretty much interchangeable between most traditional 3d apps so assuming you're familiar with the toolset in 3dsmax then your best bet is just to find one of the numerous tutorials in this sub-forum on how to make LOD models for SL mesh and follow along, ignoring any specific information regarding the blender toolset (or whatever app the tutorial is based on) and substituting the appropriate 3dsmax tools.

    Here's a tutorial created by Penny Patton that covers the basics and should help you get started Optimization Tutorial: Creating Your Own LOD Models!

    I'd also recommend searching the forums for posts related to 3dsmax just to see if there are any specific limitations that you need to be aware of or recommended workflows you should follow when preparing your meshes for upload.

    and we have stated time and again why static examples dont work. The sl avi doesnt work with animations because it doesnt have enough polygons it moves like an automaton. The examples which are also static or limited animation prove nothing. The person that posted the original image is an "let optimise everything no one will notice the difference between my original image and what they have now" The fact he has since posted more detailed avi's shouldnt detract from the fact he considered the first one "No one will notice a difference" ie his opinion is suspect

    The person that posted that image has already said that he did so because that is his personal preference style-wise.  He then provided further examples of less stylized and more realistic character models (all of which you seem to want to conveniently ignore so you can harp on about the first image and how much you dislike the aesthetic).

    As far as animation goes, if you don't like that particular animated gif I suggest you follow the link I posted and read some of the articles, even better do a google search and learn a little about what IS possible rather than just declaring something is impossible simply because you haven't seen anyone do it properly in SL yet.

    The ceiling for quality of content is NOT defined by "the best stuff you've seen in SL", and if you try to argue from the position that it is you aren't going to win the hearts or minds of anyone that's taken the time to research what CAN be done.

    they litterally posted a picture of a yasuo mesh model and said "would you change to this?!" and honestly I'm not even getting that from everyone elses posts either. its just pictures of stolen models and "MuH pOlYgOnS"

    yeah I get the gist of what everyones saying: "Just use a model from another game!" wich is illegal.

    No. What some people are saying (and others are vehemently disagreeing with) is that you don't have to use hundreds of thousands of triangles to create a good looking character mesh that can be animated realistically.  So far the only mention of using stolen content has been in your own posts.

    ETA. As a matter of fact if your aim were to create a mesh avatar that animates realistically in SL the very last thing you should do is try to use a character mesh from another game.  The topology would be designed to work with a completely different rig which would make skin weights an absolute nightmare to get right and would still look terrible compared to a mesh that has had its topology designed to work with the SL avatar rig!

    as opposed to...? what? the thousands of meshes they're ripping from that game and other games that people are making L$ off of right now?

    Hi, welcome to the thread!  Since you seem unfamiliar with the topic being discussed let me fill you in.  It's a discussion about what content creators COULD do to improve their content without having a detrimental effect on the visual quality of the content they're creating. 

    If you're looking for threads that deal with the subject of the morality of creating original content vs stealing content from other games/platforms you'll find there are plenty of those too. 

    Alternatively you can attempt to derail this thread and discuss the subject here, in which case I'll probably end up agreeing with you a lot because I'm very much opposed to ripped content in SL myself.

    No the point is from the op, that some of those that suggest stuff is bad content is because they view sl in a different way and regard it as "no one will notice the difference because it wouldnt make a difference to me" which i think this thread has shown to be wrong.

    I am all for optimisation until it affects my QoL. My objection to optimisation is precisely that. Optimise away, the moment you interfere with my sl QoL you have optimised too far. The picture I posted in the op was suggested by an optimiser as no one would notice a difference. Most posters have said yes we would

    The problem is that you seem to be arguing that having an avatar that looks like this...

    image.png.e3830d4a6a7698c63a3935c70f6085

    and moves like this...

    ShldrArmRotationFront.gif

    is somehow going to adversely effect your SL QoL.

    If you can look at these two images in comparison with most SL content and honestly say that you think SL content creators have no room for improvement when it comes to optimization and rigging/animation, then I guess we really are living in two completely different virtual worlds!

    Yes and your point is?

    The point is there's a lot of poorly made content in SL.  Those that know better keep trying to educate those that don't as to what makes "good content" in the hopes that once they're better informed they'll start making smarter purchasing decisions, thereby forcing creators to start creating responsibly.

    Unfortunately a lot of the people that don't know any better seem to think that because they spend a lot of money on "bad content" their opinions on what constitutes "good content" should carry as much weight as the opinions of those that do know better, which will never happen because those people... know better!

    Its not just about the textures though, animations stretch and move the body in various ways. I have seen people with very good shapes they did for the system body and they look great when standing. Then they go into a pose and well the straight lines become obvious because the polygons arent sufficient density to adequately smooth the curve

    So even with perfect high-res textures, an avatar like this will look like crap as soon as it moves.

     

    You don't need a high polycount in order to achieve realistic movement when animating a character model, what you do need is a good underlying topology and an understanding of how to use skin weights to simulate realistic muscle movement.

    The model in the images below has a lower polycount than most mesh avatar meshes you'll find in SL and no high quality skin texture yet when animated  it manages to convey more realism than any high poly SL mesh body I've ever seen.

    No amount of triangles will compensate for a poorly created animation or pose, the only solution for that is to stop buying animations from animators that don't understand the concept of joint constraints.

     I think if I owned a residential sim, I would have a list of "approved" houses that people could choose from. A big, big long list so that people didn't feel restricted in their choice.

    Of course if LL tried this, no matter how long and inclusive that list of approved houses may be, there'd be the inevitable uproar around the "favoritism" LL are showing by including some creators and excluding others, resulting in yet another incarnation of that most loathsome of SLs fictitious elite ruling classes, the dreaded FIC! xD

    IIRC, doing that is a viewer anomaly and will not survive leaving the sim and coming back, relogging or the object leaving the interest list and returning.

    Interesting.  This used to be true of passive objects, but if the object was made active (by adding an empty timer event and llSetTimerEvent(99999999999.9) for example), the texture repeat settings would persist. 

    However I just tested this and even without the active timer event the texture repeat settings persist when leaving and re-entering the region, relogging, taking the object to inventory and re-rezzing it, sending it to another avatar in a different region, etc.  In fact I can't seem to find a single instance in which the texture repeats are reset with either the LL default viewer or Firestorm.
