KateChu4834 Posted January 10, 2018 Share Posted January 10, 2018 hi,i am new player. i try to make a house. I made a mesh and its physics they are same size in 3ds max why is different in game? it become small and wrong place. :(:(:(:( Link to comment Share on other sites More sharing options...

Welcome to SL and the forums, Kate! 3 hours ago, KateChu4834 said: they are same size in 3ds max why is different in game? Check for loose vertices. The uploader will autoamtically scale all LoD models and the physics model to the same overall size as the main one. But when ti calculates the size of each model, it takes everything in the dae file into account, including any isolated vertices that may have accidentallyended up far away from the actual model.

OptimoMaximo Posted January 10, 2018 Share Posted January 10, 2018 Hi Kate and welcome =) to me your issue could be due to the scene scale in Max, it should be set to meters by default, check whether that's the case. If all is good, you could double check whether your objects have non uniform xform: translate and rotate values should be all zeroes and your scale at 1 for all objects. I just checked and it has the same name as it does in Maya: Freeze Transformations https://forums.autodesk.com/t5/3ds-max-forum/freeze-transforma-tions/td-p/5475442 1 hour ago, ChinRey said: Check for loose vertices.

That would make the bounding box bigger, from the picture, instead, i gather that her physics models are being shifted away and scaled smaller than intended. Moreover, both Maya and 3DSMax don't allow floating (unconnected to a shape) vertices like Blender does, so it couldn't be the case anyway. The minimum for some geometry to be unconnected to a shape is a triangle. 1 Link to comment Share on other sites More sharing options...

The uploader is supposed to handle those issues. But if Max is smart enough not to leave stray vertices in the scene, yes that must be the answer. It opens up for some really interesting options for having LoD and physics models in sizes different from the main model too. That may be useful some day...

It does, but when that happened to me from my Maya scenes, freezing transforms solved the issue for me, as wel as the scene scale. Maya defaults to centimeters in all instances, and internally keeps thinking in centimeters even if you set your scene to meters. In the past, with previous Maya versions, i was forced to keep the scene in centimeters to keep the scale right because changing to meters always gave me a centimeter scale object, very very small, like at export it set the scale to cm as default, and writing down the meter scale scene unit value as they were, and not recomputed to fit a meters-to-cm scale scene conversion. Now i work in centimeters by habit, if ever need a different scale i just change the grid settings but for me, 3 meters length will always display as 300 units (cm). I never tested the scene scale again since then (2011). But working in cm has its advantages, at least for me Link to comment Share on other sites More sharing options...

So, the search for The One Thing the Second Life Mesh Uploader Does Well still goes on then. Will there be a prize if somebody ever finds it? 1 Link to comment Share on other sites More sharing options...
OptimoMaximo Posted January 10, 2018 Share Posted January 10, 2018 They are software engineers... the science behind engineering isn't the search of the absolutely perfect. For engineers, the "good enough" works and so that be 1 Link to comment Share on other sites More sharing options...

Is your house made of multiple mesh objects, exported as a single DAE file? But your physics mesh is only a single object? If that's the case you need to include the same number of physics objects, as there are visual objects. And you will have to follow a specific naming convention, which can be found there: Link to comment Share on other sites More sharing options...
Aquila Kytori Posted January 10, 2018 Share Posted January 10, 2018 You didn't say if your house is a single mesh object or a linkset of many different objects. This can happen if you are uploading several mesh objects together but provide only one Physics mesh for them all : Each mesh Object needs to have its own corresponding physics mesh. If uploading linksets then you should follow the correct naming convention : see artons first reply here 1 2 Link to comment Share on other sites More sharing options...

The minimum for some geometry to be unconnected to a shape is a triangle. I can have stray vertices in Max, no problem. They can be used to enlarge the bounding in SL as well. They only need to be at the beginning of the vertex list in the collada file to make that work. 1 Link to comment Share on other sites More sharing options...

OptimoMaximo Posted January 10, 2018 Share Posted January 10, 2018 As soon as a unconnected face gets less than 3 vertices, Maya deletes them all. The bounding box offset in Maya is achieved using triangles. 1 Link to comment Share on other sites More sharing options...

The impediment isn't in the cutting, Maya impedes the formation of "left over" geometry if that geometry doesn't make a face. Link to comment Share on other sites More sharing options...

Ah, I am guessing that very impediment and lack of it sits before the differences in cutting then. Being able to have that leftover geometry and manipulate or correct it is an intermediary step. I always liked the feeling of being able to cut anywhere and make a face anywhere at any time. Link to comment Share on other sites More sharing options...

Indeed, i'm saying that if the geometry doesn't make a face, Maya impedes its creation or permanence. Of course i can create as many faces in as many disconnected places i want.
