Question by ronronmx · Nov 26, 2011 at 07:06 PM · shaderlightingshaderlabvertex-lighting

Is Vertex Lighting still computed if no lights are in the scene?

Quick question about vertex lighting in vertex lit shaders, or even surface shaders for that matter...

Let's say I only use lights to bake my Lightmaps, but in-game, all lights are turned off/deleted, will the shader still computer vertex lighting at runtime and be slower then a UNLIT shader?

I understand that if I have realtime lights in my scene at runtime, the lighting will be computed and the shader will be slower then an UNLIT shader, but if I don't have ANY lights in my scene at runtime, does this still hold true?

Thanks for your time! Stephane
