I had the exact same problem until I changed the file type of the textures that the ST7Compiler was generating. I’m a new user, so it took me some trial and error. The file type was set to “DDS” by default. Importing the resulting .srt file into UE4 gave me all-black materials and no textures.When I changed the file type to “TGA” it worked fine. You can specify other formats to suit your needs. Also, don’t forget to choose your appropriate platform (DirectX 11, OpenGL, Xbox One, etc.). I hope this helps someone!
