Making polys realy bright with texturing

[wolfman8k]

If I have a texture mapped poly, the brightest I can make it is the color of the texture itself. How can I make it realy bright, like white?

Also, while i'm here, How do I unbind a texture so I can draw non textured colored polys?

Thanks,

Well, you disable texturing like when you once enabled it, with:

glDisable(GL_TEXTURE_2D);

and

glEnable(GL_TEXTURE_2D);

Thanks, Does anyone know the answer to my first question?

You could use multitexturing and the GL_ADD texture environment on the second texture unit, with the texture for the second unit being all white (or whatever color).

wolfman,

You could also use separate_specular_color to add the secondary iterated color AFTER texturing. That or multitexture with texture_env_add would be my suggestion.

If you're lightmapping you can use glBlendFunc(GL_DST_COLOR,GL_SRC_COLOR). This will give you a light range of "0..2" ... well, it's still 0..1 but any number above 0.5 will brighten the pixel. The max brightness will be twice the texel colour.

a better way to unbind the texture is to do
glBindTexture(GL_TEXTURE_2D,GL_TEXTURE_2D),
and of course, don't ever use the default texture to upload something
