i have a bug with eevee when i rendering, my volumetric ambiance disappear sometimes without any reason. I noticed it once a sequence was rendered, some frame, totally random, i haven't my volumetric.

Look for exemple frame 187 its ok, 188 bug, i retry instant to render 188, and it's ok.

render frame 187 render frame 188
render frame 188(2)

I think it may be the fact that my object with volumetric shader have a animation, it grows until the camera is immersed in it, and finds the volume. But when this object become static, after on my animation, i have a same problem.

I can't make this volumetric on world, i have already it for ambiance of full scene. My animation it's like putting your head in water.

If somebody have tricks to avoid this, I can save time rather than render bugged frames one by one.

Thx community !

  • $\begingroup$ I cant fix this bug, really no solutions, but i have found how resolve my problem, using 2 world volume with a mix shader for switch from one to the other. $\endgroup$ – Pomess Aug 18 '20 at 14:16
