I know this is probably a small problem, and i might sound like a stupid person. So i make a lot of 3d assets (FBX) and ofcurse i make textures for them. so i import my 3D asset into UE4, then I import the texture,then i create the material, but when i put the material on the model its just 1 color. for an example - i have a 3D Rock, and i make a gray rock texture and when i apply it its just gray, it works ok in some of the models, but most of them are just a 1 color instead of a rock material i made. Thanks, and sorry for the stupid question
