Title: Question about environment map and Adaptive Environment Sampling
Post by: maou42 on 2021-01-18, 05:08:15

Hi

Does the adaptive Environment sampler work if there is no map in the slot it but only a white colour in the color swab?

And would it make any difference if I used a Coronacolor map in the slot instead of the white color?

Thank you

The adaptive environment sampler always works, but with some environments it will give less benefit that with other.
If you use an HDRI, particularly with high contrast (strong sunlight), you will get most benefit.
If you use Corona Sun + Sky you will get almost no benefit.
If you use a solid color (be it Corona Color, 3ds Max output, or any other node), you will get no benefit whatsoever.

*By "no benefit" I don't mean that the rendering will be slower than with other samplers - I just mean that there will be no speedup which is otherwise expected.
