StepbyStepVFX Posted January 6, 2019 Share Posted January 6, 2019 (edited) Hi All, I am rendering a simulation of smoke and it seems I got some "flickering" or "jumps" in the opacity values of my smoke. It is obvious between frames 181 and 182, where the smoke dissipate a lot in some areas, then revert to previous values some frames later, between 184 and 185. And again between 188-189 and 189-190. I am using the Pyroshader (without noise, without emission, only smoke, nothing fancy... no remapping of value, really straigth out of the bos shader). Nothing fancy neither in Mantra : volume limits up to 1, and opacity limit to 0.995, normal value). Did this already happened to someone ? If yes, any thoughts on how overcome that problem ?

StepbyStepVFX Posted January 6, 2019 Author Share Posted January 6, 2019 Found that using Raytracing instead of Micropolygon rendering was giving cleaner results, as well as increasing the Volume step rate (volume quality) Quote Link to comment Share on other sites More sharing options...
