I’m still trying to figure things out. I understand the difference between using GLSL textures and singletextures/multitextures is that with GLSL you get some additional effects such as normal mapping, real-time shadows, etc.
But what about singletextures and multitextures? If the BGE is just blending different textures in real-time using Blend modes/types such as mix, add, saturation, etc. can’t I just do exactly the same using layers under Photoshop/GIMP and use the single output texture in the BGE?
Considering both singletextures and multitextures are for older machines that don’t support newer OpenGL versions and are probably running on lower processing power and memory, isn’t multitexture mode redundant?
