Vrayfastsss2 - Black dots

[Dudateles]

Hello everyone,

I'm using the VrayfastSSS2 material and I'm getting some strange black dots (follow image attached). I've tried increasing the render settings but it still there. I'm using simple single scatter with 16 of single scatter subdivs. The prepass rate is 1. For GI I used Irr Map and Light Cache. If anyone could help me with some idea, I'll be grateful.



Cheers,

Do they change if you increase the prepass rate? I mean, are they part of the sss effect itself, or something else?

Best regards,

Vlado,

I increased the prepass rate to 2, but still get this black dots. It not happens with every frame and balck dots position is randomized. I can try to render with a different material to check if the problem is with SSS. Once more, thank you Vlado for your support.

In that case it would be useful to get me some what to reproduce the issue - a scene or reproduction steps. You can send the scene to vlado@chaosgroup.com

Vlado,

Now, I'm rendering with Brute force as Primary Ray and the problem was solve. Thanks for your support and I'll post the final result soon. It's an animation that I did to test the softbody and retime otpion.
