Sorry - I didn't do exhaustive testing with that (it was just off the 
top of my head). You'll need enable lighting for the specular pass, or 
else it'll draw solid. i.e. put:

	 	glEnable(GL_LIGHTING);
	 	glEnable(GL_COLOR_MATERIAL);

Before the "// Second pass to add specular highlights" bit in 
IRTransBuffer_Draw. That should do it - I think...

There's no real problem, they're just a pain in the arse ;)
