I’m running Leopard 10.5.5. My application need to use as much texture image units as possible. However, according to information from Apple webpage http://developer.apple.com/graphicsimaging/opengl/capabilities/index.html , it seems like they “hard-coded” the number of texture image units (MAX_TEXTURE_IMAGE_UNITS_ARB) to 16. Is there any way to overcome this limitation? (I know for sure that my graphics card support 32 texture image units).
