Hello,
in severel recent jobs i wasn´t able to render artefact free volumetrics with meshlights/arealights (see attachment). It seems at the boundaries between the arelight/meshlight those splootches are happening. Only spotlights are "splootches" free so far.
If i attach a "V-ray fluid shading quality" properties to the fluid node and set the VolumeShader to "VrayEnvirnomentFog" it works at the cost of heavy rendertimes. I tweaked every parameter for PhoenixFD Mode like Stepsize, Maxsteps, Subdivs whatever or the probalistic settings in the rendering overrides without success. Also increasing the maya fluid resolution to insane values didnt help. This relates to maya fluid containers as well as for vrayVolumeGrids with vdb.
Please find attached two videos, one PhoenixFD Shader and for comparison VrayEnvironmentFog and a maya file.
Thanks,
Andy
