I have already submitted a ticket on this but would like to see if I can get some additional help as well.
Currently I am using Hexagon 2.5 for making my models and then importing them into Carrara 8.0 for texturing and animation. I am also using Unity3d for my game design so I am importing all the items I am making into it. When I import the models from Carrara to Unity, my models will show up transparent on some if not most of the sides that are on the outside of the model. This only happens after I import my models from Carrara, not Hexagon as I have attempted to import directly from there and have no issues.
So far what I have attempted to do with the export from carrara is go through the file format of .fbx so I can keep the texturing and animation that I’ve worked on, as well as .obj and the issue persists. I have even attempted to just import the un-altered model from Hexagon to Carrara (and before doing anything) then export it in either .fbx or .obj and the issue persists (with .fbx it throws an error in Unity, the error is not very helpful as it only says to report the bug).
Here are the steps in detail
1) create model in Hexagon 2.5
2) export as .obj then import directly into unity (clean and complete model)
3) import .obj/.car into Carrara
4) export as .fbx (to retain texture/animation) and import to unity (transparency issue)
5) export as .obj (texture manually) and import to unity (transparency issue)
Any help would be helpful, I will be trying additional things to see if I can figure it out and will update as things progress. Thank you in advanced for your help.
