Artifacts in fire render

Recommended Posts

Hey everyone,

I have a weird problem with my fire render. I have some artifacts (the area around the rock inside the fire) and I have no idea what is causing them. Please see attached image.

I am using a distant light with PBR and raytrace shadows with Blackman volume filter and filter width set to 1.25. I tried Micropolygon as well and it was the same. Any ideas?

So I ran some tests and I believe I have found the cause of the problem. See attached images. When I simulate with Burn Rate set to 0.9 or 0.99 I do not get any artifacts. However, the same sim at Burn Rate set to 1 is creating artifacts. No idea why this is the case, really. Anyone have any ideas?
