Disabling Multitexturing

OpenGL OpenGL: Advanced Coding

Hi
I’m rendering a scene using multitexturing extensions, is there a way to disable the multitexturing, to do something like this:

Enable Multitexturing
Draw Scene
Disable Multitexturing
Draw Other Scene

thanks

Very simple answer. (really I think this would be more appropriate in Beginner’s Forum)
Remember to enable/disable GL_TEXTURE_2D (or whatever) for every active texture unit.

Here I go with an example with 2 units:

1] Enable multitex for units;
glActiveTextureARB(GL_TEXTURE0_ARB);
glBindTexture(GL_TEXTURE_2D, tex0);
glEnable(GL_TEXTURE_2D);
glActiveTextureARB(GL_TEXTURE1_ARB);
glBindTexture(GL_TEXTURE_2D, tex1);
glEnable(GL_TEXTURE_2D);

2] render geometry

3] disable units
glActiveTextureARB(GL_TEXTURE0_ARB);
glDisable(GL_TEXTURE_2D);
glActiveTextureARB(GL_TEXTURE1_ARB);
glDisable(GL_TEXTURE_2D);

4] render non-textured geometry
