Fireflies with lightmix - reflection pass

[martin_hennrich]

Hi there,
as seen attached im getting fireflies/noise in refl, ies, hdri and self illum pass. Lightmix is enable, all standard materials no fancy stuff, AA is 2-32 0,007 bucket, overall pretty high settings. Using latest stable nightly version of course.

• Problem: using a lightmaterial for the ceiling lines - i cant raise subs, there are no!
• Glas refl glossiness 1 or 0,99 makes no difference
• Fireflies appear in every single pass like hdri,self illum or ies, so its hard to find out what causes them
• Funny enough - refrac pass is absolutely fine

Any suggestions/ideas welcome...

Hi martin_hennrich,
can you please share some more information like what V-Ray and Cinema 4D version you're using? What render engine you're using (V-Ray or V-Ray GPU) as well as the sampler type (Bucket or Progressive). We've recently released a new version (Hotfix 2) that might solve the issue you're having, and if possible give it a try. Also, if possible sharing the scene with me would help us find the source of the issue and resolve it if there is a problem.

The fireflies have nothing to do with the removed subdivision options and won't solve them. Having the scene would help us give you more information on this since it isn't easy to reproduce such a case with any scene.

Thank you for the feedback.

Hi Ivan,
R23.110 Vray from March 26 nightly builds(30689), CPU Rendering with DR, Bucket. Currently rerendering with Hotfix 2 to check if the problem still exists. Otherwise ill send you the scene via wetransfer.
