I'll work up a test application and see if I can figure out what the problem is. In the meantime, check that you're passing texture coordinates to each texture unit using glMultiTexCoord{1234}{sifd}[v][ARB](). That was the thing that got me last time I used multitexturing.

Enigma

Don't bother! It was indeed the lack of glMultiTexCoord{1234}{sifd}[v][ARB](). I thought I could get away with using glTexCoord2f() only because I thought whe texture was being buily into memory as a single texture.

Thanks for the help, it works perfectly now!
