Hello,
my question is related to speed up the calculation of
CoronaVolumeMtl (clouds, for example).
As we know,
Single bounce only = ON, the
rendering time is very low, but also the quality.
When it's ON, the rendering time is HUGE! Almost impossible to use in production.
Corona uses 25 bounces (as a default).
With 5 bounces it's enough to obtain a good quality, with low rendering time. ( I used a little bit of Emission in my test)
With 10 (with a little of Emission) I have almost the same rendering, but the rendering time is so different!
Maybe it's good idea to
add a new parameter to set the light bounces for
CoronaVolumeMtl.
We are speaking about 20 minutes (10 bounces) vs 42 minutes (25 bounces) with almost same result!
Ok, I know that we don't want to add too much parameters as in V-Ray, but... here we should do an exception =)
What do you think?
PS: with 5 bounces, I had 8 minutes with NL= 0.7 (^__^)
