The limit is imposed by driver, you can read it with the openGL calls int maxTexture; glGetIntegerv(GL_MAX_TEXTURE_IMAGE_UNITS_ARB, &maxTexture);
this number should be 16 since geforce 6. BTW, why are you usinge 8 texture? O_O They are a lot. 2009/1/12 Martin Großer <[email protected]> > Hello Robert, > > yes, that was what I mean. :-) Also I can use 8, 16 or 32 textures, when > this the driver and the hardware this number of textures supports? > > In my application I use a limit of 8 textures.
