OK, I'm lost. I made a chair. Sculpted in ZBrush, export OBJ, import to Maya. Did the UV map, added texture and AO. Export FBX. Convert to DAE. Upload to SL, no problem, looks ok. Then I decided I wanted to accentuate some of the sculpted detail. So, re-open ZBrush, do a little tweaking. Export OBJ. Import to Maya. Re-do the UVs, textures and AO. Try to upload to SL... WARNING: validate_model: Model has no faces! WARNING: doLoadModel: document has no visual_scene The first (successful) model was done in Maya 2014 and used FBX Converter 2013.2. Same thing for the first failed attempt with the new model. I brought the model into Maya 2013 and re-exported, used FBX Converter 2013.2. Failed upload. Updated to FBX Converter 2013.3. Still failed. Reversed all normals. Still failed. Reversed normals back again. Still failed. Reduced the poly count. Still failed. Removed all textures from the model. Still failed. Added the textures back again. Still failed. I have no idea what the problem is or how to fix it. No idea why it worked once but not the rest of the times. Any suggestions?
