Jagged edges when using Post Volume Effect Fog

[tombyrom]

Hello,
I am trying to use the Post Volume Effect Fog as it gives the exact settings and look I need (distant/aerial fog) which I cannot achieve with any other fog method in Octane.

It's great but unfortunately, I am getting jagged edges around objects when the fog is on, I have checked all my settings I can't see anything that I can change to fix this? Is this something that can be mitigated? Or is it a limitation as it is a post-process effect?

See my example, the upper part of the model on the edges is jagged when this feature is turned on.

Thanks

Hey,

this post volume, is that under the camera Post Processing setting?

I would like to try this out.

thanks

It is yes and apparently no one talks about it. But its perfect for this distant aerial fog.

Also, I fixed my own issue, see screenshots attached. Effectively it was due to certain values, and the fog was too close, with new settings I see no issues around objects closer to the camera but still get the distant fog look I want.

So this prob only works well when it's far away, if you need close-up dense fog then use a scattering medium on the environment and use the emission technique for no noise.

amazing, though scene scale must me accurate
