Pyro Scatter Flickering

Recommended Posts

Hey. I am facing an issue where the scatter of the pyro is flickering. I am talking about the scatter field you get from the pyro bake volume. I isolated the scatter field and checked it and as expected it's flickering. Flickering means it's kind of getting bigger and smaller over time. You will understand what i am saying when looking at the GIFs below. The temperature field that is used to create the scatter field does not have this issue. So pretty sure it's happening because of the smoothing. Any tips on how to get rid of that flickering? check out the scatter field flipbook too. It's clearly visible in that.scatter_flickering.thumb.gif.734d0c7457a0e5b019137fb7a4c768b2.gif

the vdbsmooth1 node inside the pyrobakevolume SOP is buggy.
to fix it, you can convert to volume+volumeBlur and back to VDB.
