Multi-texturing problem
Author
Is it possible to render more than 2 textures in a single pass, or am I doomed to doing 2 passes?
I read that only GEforce3 and up have more than 4 texture units (I have a GEforce 3, but i want to make my game run on more than just my comp.)
However, I know that glClientActiveTextureARB supports up to 4 textures. So can you render 4 or not?
I got two textures to render fine using multitexturing, but when I added two more they would not display.
Here is the code: Is there anything I can do, or do I have to render twice?

You can use as much textures in one pass as you have texture units.
a side note: if you have same texcoords for all texturing units you can just set this array for GL_TEXTURE0_ARB and the rest will use that (I think
)
There are more worlds than the one that you hold in your hand...

everythings in your codes mixed up use
glClientActiveTextureARB(GL_TEXTURE0_ARB);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glTexCoordPointer(2, GL_FLOAT, 0, tVA_tex);
glActiveTextureARB(GL_TEXTURE0_ARB);
glEnable(GL_TEXTURE_2D);
terrainTextures[0].Use();
yes 4 textures in one pass (gf3) is possible

glClientActiveTextureARB(GL_TEXTURE0_ARB);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
glTexCoordPointer(2, GL_FLOAT, 0, tVA_tex);
glActiveTextureARB(GL_TEXTURE0_ARB);
glEnable(GL_TEXTURE_2D);
