Hey, I was wondering if I was the only one having this issue with Karma on H18 : I can't use geoLight or emissive Volume to light an other object. Any idea ? Maybe it's still impossible on the early beta version.. Sylbert. PS : I haven't find a way to setup the amount of ray limit in Karma setting as well..
golubevcg posted a topic in Lighting & RenderingHello 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.
