@Nbohr1more has pointed out a strange visual glitch with the hanging light model: models/darkmod/lights/extinguishable/cagelamp_hanging.lwo
It's casting unwanted shadows when in the shadow maps mode.
It has two surfaces:
- main surface with material tdm_streetlamp_metal which is noshadows - this one is OK
- bottom of the holder with material tdm_coals_hot - this one is supposed to cast shadows but for some reason it's not casting shadows in stencil mode - it looks as if the surface is deemed back-facing by stencil code even though it's clearly front-facing to the light view.
I would appreciate anyone shedding some light on why the bottom surface is getting culled with stencil - is it a renderer bug or am I missing something? Maybe something's special about the model itself?
The map in question is NHAT (anoot.map)
