Summary0004367: nodiffuse and nobump Light Entity args do not work
DescriptionBroken form tracker 4292

nodiffuse and nobump Light Entity args do not work

It may be possible to get this working in tr_render.cpp
but it seems that Bump and Diffuse are tangled together in
material.cpp and the code to support these options is lacking
compared to the nearly complete nospecular setup.
TagsNo tags attached.

To get around possible wonky branching logic, just (logical-or) the failure against a known working failure condition:


if (!surfaceRegs[ surfaceStage->conditionRegister ] || backEnd.vLight->lightDef->parms.noDiffuse )

This works on nospecular but "nobump and nodiffuse" still don't work using the same method.

I have a monstrous idea of duplicating the entire evaluation chain for each entity arg but that's probably not a good way forward.

The other option is to make a ton of alternate ARB shaders without these stages.
Not ideal...
