I'm working on something here that requires irregular light shapes so I chose to use either mesh lights or VrayLightMtl with the option "Direct illumination" turned on. The problem is, these two approaches are quite slow to render compared to other types of lights (plane, sphere...) and there's a lot of noise that is hard to clear. Is this normal? Any way to speed it up?
You can find below a simple scene for testing. The mesh lights have exactly the same shape as the ordinary vray plane light objects but they take twice as slow to render compared to them (and even worse in more complex scenes).
