Hi,
I have this very strange problem with GLSL on a radeon 9600 128Mo board, running catalysts drivers 4.8 and upwards :
I use shader designer as GLSL IDE, and many of the shaders that use multitexturing do not work.
For instance, running the bumpmap shader yields a teapot textured with the actual bump map texture as diffuse color, the environment map shader will just produce a green teapot,
Even more strange is that the brick shader will just give me a red teapot with a single green brick, the gooch shader does not work either…
And I have other porblems with pbuffers like being unable to write into the back buffer of a double buffered pBuffer, and unable to use the back buffer as a texture.
I had to switch back to catalyst 4.7 to get the shaders of shader designer work again, but I still have this problem with render-to-texture, pbuffers and back buffer rendering and texturing. I know that the pbuffer extensions are wgl* extensions, so that they’re windows API related, but I thought they were exposed to the GL programmer through the catalyst driver?
The strangest aspect of this “bug” is that the render monkey 1.5 GLSL examples seem to work (except for a few of them, like the bounce shaders which gives me three white spots on the screen)
My own shaders work, but they’re very simple stuff.
I already notified this problem to typhoonlabs, which could not help me.
If someone could try this to see if it is reproductible? or could give me some hints with multi surface pbuffers and back buffer rendering…
Btw I’m running a P4 2.5 with XP SP2, radeon 9600 128Mo with catalyst 4.7 (4.8, 4.9, 4.10 do not work at all for me)at the present time.
And the problem was reproduced on a Radeon 9600 mobility laptop.
Thank you…
