I exported a plane of 100 intersections by 100 intersections as a .3ds file, 1362324–67876–$plane_100x100.zip (132 KB), and imported it into Unity.
Unfortunately no shader with texture support textures it. The material I assign to the plane receives the texture in the preview but the plane itself gets one color only.
What can be the cause for this?
Is it possible to create a custom “detailed” plane in Unity3d itself?
Most likely the model doesn’t have UV. A plane is one of the few corner cases where its fairly simple to “visualize” how a texture could be mapped onto a 3D model. But how would you wrap a 2D texture onto a chair?
Unity doesn’t try to solve this problem, the 3D tool where you made the original plane has a ton of tools for solving this problem. So go back to your 3D tool and set up uv coordiates and then export the model again.
