I’m a new Unity user and I downloaded a .fbx model of a low poly race track. I dragged it into the scene but it shows up as grey even though it looks like there is a material already assigned to it.
Where did you download it from? Is this an FBX file by itself, or an FBX file with some image files? If you import an FBX file that has materials assigned to it in an external application, it’ll try to make materials for that mesh on import. But if it can’t find the textures as additional files with the FBX then it’ll just create blank materials with no textures. It may instead also set a solid color for the material if one was set in the FBX. In this case it’s creating a grey and a red material and applying that to the part you have selected. Some other parts may have one of a handful of white materials. But if you did not also get textures with the FBX file, or did not also I add those to your project folder, or Unity for some reason was unable to match the textures you did include to those in the FBX, you’ll need to create new materials and assign them to your mesh.
