Member Data Documentation

dummyLightSampler2DShadow

uniform sampler2DShadow glsl::LightingEnvironment_LightUniforms_glsl::dummyLightSampler2DShadow

Used by computeDirectLighting for lights that do not have shadow maps on them.

We don't pass dummy shadow maps per-Light because OpenGL has a small, limited number of samplers (when not using bindless texture), and that would cause scenes with many lights to exhaust the available samplers unnecessarily.
