I love it ChimKami Congrats!!!

Aloha I've run the tear test with default LODs and no physic model because I wanted to see how the uploader was going to calculate them. And I wanted to see what happens with that when a mesh becomes more complex and detailed. That's why I've choose an organic form with a Subsurf of 1 and 3. But more tests are needed about, as Drongle one (with more photos please! Remember not all people reading these post have a good english... as me, per example... so any graphical material are welcome to understand you all better). Arton, thanks for the article. Is the way I use to work, but I still without fully understanding SL Uploader and why i guet some ramdom of toppic results with it. Yeah, it's for driving nuts Drongle. But how little enough are those difference when we are dealing more complex meshes? Drongle, I think I didn't understand you when you talk about looping... when one do a manual subsuf model by looping, one use to have more control about final number of verts/faces than when one use the Subsurf or Multires Mods in Blender. Using the Subsurf, in theory, what can give you is a more uniform mesh in your model, which uses to mean a more uniform UV faces. Do you mean with same final number of verts between manual looping and Subsurf Mod? About the UVs... my personal opinion is that I'm going to still working as always: customizing my UVs for texturing better (specially because I work with ZBrush too and have a different unwrapping method than Blender). For me, by now, it's better, but's that's my personal choise. About Tris vs. Quads... my partners and I did some time ago a simple test about with a LP organic leaf. We were thinking that maybe converting to Tris the leaf could help to minimize LI, because in theory will help the uploader to don't have to convert Quads to Tris, or will not have any difference. But our result was that Quad model was giving quite less LI than Tris model. For triangulate our Quad Model, I used Blender's Tris Modifier. UVs unwrapping method used was Projection. I don't remember if shading method was flat or smooth, sorry. We have to remember that saving 1 or 2 prims can be important for mesh creators (sellers and artists too) that have prim limit restriction. Per example that's my case: when I do big art installations in a full sim (my last one was with my team: The Sea of Cubic Dreams at LEA25. All mesh*. We spend over 10.000 prims), I use to not be quite worried about if my assets are some prims down or up LI conversion, but when I have to design with prim limit restriction (we reproduct a part of it for a charity event, but with a limitation of 300 prims)... the story change. Any mesh creator should need to plan better the "how to do for SL" uploader (efficiency), users (quality) and land LI restrictions their stuff before starting modeling. And that means that any tricks that can help to optimize a model, without loosing really much quality at least in Med LOD at mínimun LI possible, can be really helpful. Understanding how much can or not be important shading and UV unwrap can be important depending of what you want and need to create. *Mostly beveled clon cubes of different sizes and editor's physic tab settings to make them interactive without scripts. The base-cube was optimized to be able to be saw at distance, also with poor graphics. The cost in prims of this cube was of 7 prims (it was big). Unwrap method used for the cube was UV unwrap with Mirror Mod. Smooth shading. Modeled in Blender 2.6.

Aloha to all I have run some tests with an organic mesh, a tear I’ve made, with the following questions in mind: Smooth shaded models give less, more or equal land impact (LI) than flat ones? The UV maps with more islands increase LI? (UV methods used: UV unwrap with Mirror Mod -generates 2 overlayed islands-, UV unwrap -1 island-, Smart UV Projection -multiple islands-) How affects subdivision level? (Subsuf 1 and 3) All tests run with default LODs. Blender version is 2.72 and Second Life’s Viewer used was Firestorm. SMOOTH VS. FLAT SHADING Observation: In the major models uploaded, smooth wins versus flat. Just in very LP meshes, and depending of the unwrapping, smooth and flat can give same LI as result. Conclusion: Smooth shading is more effective to reduce LI than flat shading. UNWRAPPING METHOD AFFECTS LAND IMPACT Observation: There’s a difference between the 3 methods used. When tear model uses flat shading, UV unwrap using Mirror Mod is the most effective, followed by Smart UV Projection and UV unwrap When tear model uses smooth shading, the better method is Smart UV Projection, followed by UV unwrap using Mirror Mod and UV unwrap Conclusion: The UV method used to unwrap a model affects LI. But why? Also it has relation with the normals? HOW AFFECTS LEVEL OF SUBSUF TO SHADING AND UNWRAPPING Observation: At Subsurf of 1: In LI, The only difference is in tear with smooth shading and Smart UV Projection, giving a lower impact. For the rest, there’s no difference using smooth or flat shading with any of the 3 unwrapping methods used In Dowload, different shading and unwrapping methods seem to affect Physics have same value than LI in tears with smooth and flat shading At Subsurf of 3: We see a clear difference in the models LI related to shading and unwrap In Dowload, flat shading and unwrapping methods used don’t seem to affect while yes with smooth shading Physics have same value than LI in tears with smooth shading, while in flat shading there’s a difference Conclusion: When level of Subsuf increases, the difference between shading and unwrapping methods is more obvious. As one can see, the method used to unwrap and choosing between applying smooth or flat shading is important related to Subsuf level. Photos, photos , photos... In case you cannot see well the pictures, here's my post about it in my Blender blog: Second Life’s Mesh Uploader: Can Smooth and Flat Shading affect Land Impact? And UV Unwrap method?--||-

Not theorical, it works. I 've use that trick for fake the bumping for several of my stuff

Buenísima! Eso no lo sabía! Muy útil, gracias!

Aloha! Fàcil: es la tecla de "subir pàgina" (o retroceder página...) Es la que sale con una flechita que apunta hacia arriba que tiene dos rayitas cruzadas (como un signo igual). Espero que te haya servido Ciao!
