vertex shader in order to
calculate lighting on per pixel base. Sampler names should not matter,
as the texture objects are rebound to my names (which should take all
texgens etc into account). Sadly I suspect th
Hello Jean-Sébastien,
I reckon that my assumption regarding the texture compare mode were wrong.
But indeed the whole problem seems to be with my shaders. I'm willing to
provide the per-pixel modifications.
I guess I'm doing something very wrong in my vertex shader. Upon

It seems to me the shadow texture compare mode is not set, which results
in strange results.
My project requieres per pixel illumination, which is why I have to
calculate all projections in the verte
IIRC a little tool called "fraps" is doing the job.
