I think that the problem I’ve been having is possibly due to some ‘rogue’ quadrangles in my meshes. When I apply the TriangulateMesh command to my models, SL seems to be happy to accept them. If you have any useful recommendations about preparing models for uploading to SL they would be greatly appreciated.
Are you into SL scripting for mesh models ? I am at a bit of a loss to work out how to update my old scripts for sailing boat sails written around the use of ‘tortured’ prims rather than mesh surfaces.
Sorry I am not very familiar with SL. I just know that gaiaclary over at #blendercoders (freenode IRC channel) works a lot with SL, pretty much maintains the COLLADA export functionality in Blender 3D. She does a lot of SL work as far as I know
