This is concrete cube object made with Blender 2.7 with Cycles render.

Notice:
1..dae, .fbx, .obj files are not textured. If you're gonna use them into Unity/Unreal Engine or something like that, you can download PBR textures as supporting items and use them for these textures.

2.This mesh has a UV map generated automatically with Blender. If you will re-paint or create another textures, you should paint it with a 3d-painting software( e.g. Substance Painter ).
