--- Comment #34 from Rico kgbricola@web.de 2009-01-28 13:06:04 --- Setting the r_HDRRendering variable has a huge influence on the rendering result (sys_spec_Shading.cfg). Setting it to 2 (Shaders = High) the game looks fine (at least objects are rendered). But setting it to 0, you have problems to see the world. Also the generated shaders differ. So I guess there is a mistake in the shader generation.
Is there an easy way to dump the input for the shader and the generated shader and compare the results?
