Hi Florin Barbuceanu

Its because UNWRAP just prepare model to be textured. UWRAP calculate UV maps, but you need calculate the actual textures onto the UV maps…

Can you please explain how can I calculate the textures onto the UV maps? I have a large model 90m triangles, I simplify it and I want to put the original texture in this model to keep some details, inside 3dsmax, but I only managed to open the obj file in 3dsmax with the checkerboard material applied.
