  1. Hello everyone! I have some problem, during the rendering of forest - i have lot's of trees (instances, using instancefile), which have bark displacement(sharedisplacement enabled), and i have volumelight from bonfire (pyrosim with edited flames shader, volumelight simply created from shelf tool, it has flames material and pyro volume as geo, i only increased amount of points in pointcloud of volumelight to have less noise in render). In all of this camera slowly flying into the bonfire. So, during the rendering of volumelight, it have this artefacts (black squares on screenshot), which i can't find the way to fix them. This "squares" are blinking, during the batch render - one frame they exist, the other - don't. Is someone meet this problem before? There's any way to fix this? Other lights don't have this bug, it's coming only from volumelight.

    My open source solution to render volume light effects in Houdini Mantra based on the first part of this paper. Equiangular sampling (better sampling around light sources) Per-Light export Physically correct result Support for colored absorption (attenuation) Source code and example here https://github.com/somesanctus/volumelight
