How do you apply 6 different textures to different sides of a cube without UV mapping? I tried something similar in Blender, with two non-uv mapped textures, but in Unity they seem to merge somehow. 
UV mapping would not work in my case since I need to make one single face of the cube display any of a 100 different textures at any one time.
Use 6 separate planes in the shape of a cube.
