Hi! I’m becoming mad with a weird rendering problem.
I am currently working on a setup allowing realistic fake volumetric clouds, and I’m very close to the goal, but there are still weird artifacts in my cloud, visible on some frames in my animations.
The topic about my WIP is here :
I plan to release the Blend file with a tutorial, but as I want to deliver something really usable, I have to fix this little but annoying problem :
Some weird artifacts appear on some frames in areas mostly in peripheral, around my cloud. I have checked dozens of parameters, but as the phenomenon doesn’t appear when rendering only a part of the image around the artifact using border rendering, it looks very strange !
I fear that it is a bug in the render engine… In such case, all my attempts to fix this problem by tweaking parameters in the materials, lights and else would be only a waste of time…
If someone has an idea about why it doesn’t happen with border rendering, I’d be the most happy of the Blenderers…
Raytracing is disabled as well as material specularity, so no possible reflections between objects. I don’t think that parts rendered with border can be influenced by something in an other part of the image.
If I dont find, I will release the Blend file as it is, in the hope that someone will find a solution, but it is rather annoying so close to the goal !
Any suggestions are welcome.
Thanks in advance.
