'Static' Cube Mapping a Planet.
Posted: Tue Feb 21, 2006 8:15 pm
Not too sure what the correct terminology is, but I'm trying to apply a cube map in a non 'environmental' way- i.e. fixed to the mesh, and unchanging with camera movement.
essentially - cube mapping a sphere with arbitrary geometry. 1024x1024 x 6 Cube Map gives us the same resolution as a 4096x4096 spherical map, so I'm hoping it can applied in this way. I've got a material with a cube map loaded, but I'm not sure what setting would be needed to make the texcoords work statically. Although env_map cubic_reflection does show everything up as working, how do I make the cube map 'fixed' to the surface? Or is this not possible?
Any ideas?
