Hello,
I just registered here but I'm familiar with the forum and Terragen
Nevertheless I'm struggling with artifacts in clouds despite all the tests I made and the tips I found on the forum.
The situation is this one : I have a scene with three cloud layers (one 2D cirrus, high level layer, one V3 medium layer and one V3 lower layer.
Rendering through a render farm, I now always encounter bucket artifacts with high res renders. Testing with 3000x1500 for instance. Artifacts are probably linked to GI in clouds, but I tested acceleration to none, GI file sent to the farm, higher "GI in cloud" setting, padding, etc.. to no avail.
At home, I never experienced that : all renders are ok, as far as they are done in one run. I experience inconsistent GI in clouds once when rendering a large image in several parts (cropping) but solved it with a pre-generated, huge GI file.
On render farm, I experienced that once and solved it with higher GI in cloud setting (very high) and probably acceleration to "none".
But now, I'm out of solution.
Any idea?
I read here that rendering a GI pass file at lower resolution (say 1500x1000) and use this file for farm-rendering at higher resolution (say 6000x4000) would work. Is that true? If so, it will be very helpfull as I can't imagine having to upload 2GB GI file for each render on the farm.... :/
