Hi! I have been searching around, trying to figure out how to get a distance fog effect. I want something where the fog obscures things in the distance more than things close to the camera, but Octane seems to treat fog (on a daylight tag) as constant throughout, and I can only get either cant see anything, or can see everything. I cant seem to get that sweet spot in between where you cant see things in the distance, but things up close you can see better. Here is a screenshot from my scene showing what Im talking about.

It is a fairly small scene, and I want to have it so the fog obscures the end of the actual geometry, but you can still see things up close. All it does now is either show everything, make everything but the hdri go black, or make everything go black. What am I doing wrong?

Hi Adept,
In addition to medium radius you can adjust density and scattering in volume medium nodes.

You have to adjust the scattering , absorption and density settings and balance them out. It also helps if you have accurate scale.

Might be better to do it the old way if the medium node is not giving you the results that you want. That way you can pick where you want your atmosphere.

I've been fighting this for a long time. I can't get the medium fog to work right in C4D or in Standalone.

I would like to see some examples people have put together where they got it to work for them the way it is described to work. I don't mind using the z-depth mask in photoshop to make some distance fog, however, it seems rather ridiculous to have to do that.

I get the same issue as the OP. Either EVERYTHING is encased in fogg (like an overlay) or nothing is encased in fog. Doesn't matter where the objects are in the scene or the scale of the scene...

Perhaps this guide from Inlifethrill would offer some insight to getting the look you are after.
