Hi. I have made a platform in Blender, mapped it, textured it, then exported as an obj, that I placed in Assets folder. The platform has 2 materials…one that include the wooden textures( 2 polygons) , and one dark(the metal), for the rest . In Unity, the top wooden polygon has texture, the lower one not. In Blender the lower polygon has texture. What is to do?
your platform is a plane, right?
if so, ether use a two sided shader a give the platform volume ( make it a cube ).
The platform is not a plane. It is a cube with extruded edges. The middle polygons…the upper and lower one (wood textured) are faces. So…each face has its own textures(on the same map). I have separated the uvs, one shell for each of the middle pollys(2-upper and lower), and two shells for the rest of the structure. It is the same mesh.
are your normals correct? ( pointing outwards )
EDIT: turn backface culling on in Blender and see if you still have the same behavior
