Hi,
i got some problems in a testscene i set up for an incoming project.
There are artifacts in the highlights no matter how high i set the sampling. The only way to get rid of this is
switch on sub-pixel mapping. Max ray intensity is on, but has no effect. I couldn´t upload the video.
There you would see a extreme flickering in the highlight.
You could try making the sun invisible, or you could make the reflections slightly glossy so that the hilights are easier to sample.
Best regards,
Vlado
I already tried that. Did n´t change anything.
Here is the animation and my file.
The way I got it to render eventually was to:
a) turn on the “invisible” option for the VRaySun light;
b) set the reflection glossiness of the blue glass material to 0.9;
c) set the refraction glossiness of the blue glass material to 0.9.
This softens the sun reflections/refractions and makes them easier to sample.
Original, where the fireflies will be very difficult to clean up:
Modified, where the sun is invisible and the reflections/refractions are slightly glossy:
I’m wondering whether V-Ray can do this sort of glossiness adjustments automatically…
Best regards,
Vlado
Ok, Thanks.
i didn´t play with the refraction glossiness.
Sounds like a good plan to me
