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 <grosser.mar...@gmx.de> 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. Is this ok for a average hardware? Cheers.

Do you mean how many texture units can be active in OpenGL/OSG at once? If my guess is correct for what you mean then the answer is simply - it's hardware/driver dependant. The answer also depends upon whether you are using shaders or fixed function pipeline as some drivers have a higher limit when using shaders. The OSG itself doesn't apply any limits so you can assign as many texture units as you wish, but it'll only work properly if the underlying OpenGL implementation supports what you are asking from it.
