coherent mode VS coherent ratio

Hi Juanjo
Last build introduces the coherent ratio value instead of the old coherent mode (on/off) value.
Can I know at what % value of coherent ratio corresponds the "on" in the coherent mode?
thanks

I am not sure. This is the information I have from the Octane developers:
"Replaced "coherent mode" with a float pin "coherent ratio", which allows you to blend between non-coherent rendering (0) and "super-coherent" rendering (1). Please be aware that for values above 0.4 you will usually need a few thousand samples per pixel to get rid of visible artifacts and values above 0.5 hardly ever make any sense."

It depends since the algorithm is slightly different. We use a coherent ratio 0.35 when we convert an older scene with enabled coherent mode.

What does a negative coherent ratio do?

The value is a percent parameter. You should use only a value from 0% to 100%
