Xennophobos Rae Posted November 2, 2018 Share Posted November 2, 2018 (edited) I am having trouble getting meshes into SL with proper UVs and textures. I'll describe my workflow (3ds Max) and maybe someone can tell me what I'm doing wrong or if I'm missing a step. I've attached an image that show the problems I'm getting in a nutshell. # I create model in MAX # I unwrap and UV the model inside MAX # I export UV template and edit it in Photoshop to apply textures to chosen UV islands # I bring the texture back into MAX and use it as diffuse map for a material # I name the material without spaces and do the same for the diffuse map's name (I heard SL does not like names with spaces etc) # I apply the material to my model in MAX - everything looks correct. # I do a quick render and again all looks correct. # I export the model as DAE (1) As Max's default DAE exporter using defaults and (2) As Max's alternate OpenCollada DAE using defaults. # I go to SL BETA Grid (Latest Firestorm viewer) # I go through the UPLOAD process for both models using the default upload settings for the most part # If I chose to include textures, I get an error - missing textures (see image), for BOTH uploads. # I upload without textures, and this works ok. # I upload the texture I created in photoshop (.png) so as to apply it manually within SL # Applying the texture gives screwy results - see image. But different results on each model. So - This is the process I followed. What am I doing wrong or what am i not doing? Any help, guide or tutorial pointers very much appreciated.

arton Rotaru Posted November 2, 2018 Share Posted November 2, 2018 Try to triangulate the model before exporting it. Add a 'Turn to poly' modifier, check 'Limit Polygon Size', and set 'Max Size' to 3. See if that helps. Link to comment Share on other sites More sharing options...
Xennophobos Rae Posted November 2, 2018 Author Share Posted November 2, 2018 I have no idea what's going on now. I retraced my steps and did exactly the same thing in a new scene and this time the manually applied texture worked fine. I suspect there's some "strange" intermittent issue with the beta grid. Of course I'm still having issues with the textures uploading WITH the model, but I can live with that as long as the UVs don't get messed up during the upload. Last night I had normal map issues, where the normal map was being applied as a standard texture on the face of the cube and not distributed as per the UVs on the model - dunno what that was about either - my next step once i get the simple diffuse working consistently. Also - I just noticed (by peeking inside the DAE file, that the OpenCollada export plugin for Max2016 is version 1.6.xxx and i read somewhere that SL only likes 1.4.xxx. The internal MAX exporter (via FBX export), creates a 1.4.1 collada so I should probably stick with that one. @arton Rotaru Thanks for the tip - i don't understand why it's needed but I'll keep it in mind. The FBX exporter already has a re-triangulate option on export - is your tip just a precautionary measure or is there some other reason to double up on triangulation?

arton Rotaru Posted November 2, 2018 Share Posted November 2, 2018 If I don't triangulate the mesh before exporting (although I have triangulate checked in the export dialog as well) I end up with broken UVs in SL. That is with Max 2015 SP3. I use the built in Collada exporter also. Link to comment Share on other sites More sharing options...

I'll see how things progress - i'm pretty new to the SL Mesh thing (as well as Max) so there's bound to be a few more hurdles ahead. When I get a chance, I'll try something a little more complex than a humble cube and make those changes you suggest and hope for the best. Link to comment Share on other sites More sharing options...

As for uploading with textures. That did work for me the few times I tried it. But most of the times, uploading just the mesh without textures is preferable, because most often you will see one or the other flaw in the model, once it's in-world. So you will upload just another one anyway. Once the mesh is final, you likely want to tweak the textures/maps some more when viewed in-world. Using the viewers local texture feature comes in handy with that. Link to comment Share on other sites More sharing options...
Xennophobos Rae Posted November 2, 2018 Author Share Posted November 2, 2018 So much to learn, so little time ... Good thing I'm only doing it for a hobby and not a living :) - I'd go broke real quick! Link to comment Share on other sites More sharing options...
