Hi,
I am getting a high cost for “InjectNonShadowedTranslucentLighting” in my scene, but can’t figure out by turning things on and off what is causing it. Can someone tell me what could be causing this?
Every light injects its influence into the translucent lighting volume textures which follow the camera around by default. This is how translucency is able to get lit, it looks up in that volume texture. The cost of the injection depends on how large the lights are, and how many there are.
If they are normal lightcomponents, you can disable the injection by unchecking bAffectTranslucentLighting. If they are particle lights (from a light module on a cpu emitter) there’s a flag on the module to control whether the lights affect translucency.
