I dont need 8 textures, but maybe the user of my application. With this application can you create a scene and you can texture an object. The reason of this question is, how many texture channels can I provide?
Because of this discussion, I think 8 is ok. Maybe I check the GL_MAX_TEXTURE_IMAGE_UNITS_ARB and create a flexible limit. Thanks at all!

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. 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.
