Multiple Texture Support BGE Is there a way to add multiple functional textures in the Game Engine. What I'd like to do is have one texture that maps the Diff and another that maps the Spec and Bump.

It always seems to override to one or the other when I have multiples placed. Is that a limitation I have to work with?
Make sure you are in GLSL mode:


Make sure each texture only affects the channels you want:


In this example I want this image to influence the specular channel, so I have unticked the Diffuse Color box and ticked the Specular Intensity checkbox.
