How to make on every side different texture on a cube in Blitz3D?
Sorry my bad English.
You can only have one texture per surface. You would need to create a cube manually in order to have a different texture for each face.
I usually don't write code for people unless they specifically ask for it, because I prefer to learn by doing it myself and I assume others do to.
Look up the following commands :
CreateMesh() CreateSurface() AddVertex() and AddTriangle()
Those should get you started. If you get stuck and need me to post the code, just ask.
