There is still no fog precision. It goes from too much fog to 0 fog and nothing in between.

And octane fog still looks flat and has no depth. There is always too much fog in front too. Octane fog just makes the whole image dull and flat unlike other renderers

You may need to increase the Medium Radius to a number that makes sense with the scale of your scene.

Thanks even with larger radius there is still too much fog upfront. Also fog goes from too much to nothing. I Wish they would add more precision in between.

Dear Otoy,
Look at this picture: lots of fog in the back and not much fog up front. Can we get this please?

Your Density value in the Volume medium is very small, very close to 0.
I think changing the other parameters makes some final value reach a limit.

You should try to increase it a bit, while decrease the Medium radius of the Octane Daylight, or varying other parameters

You can also try a Scattering map instead of a Volume medium map.

See the samples bellow.
I hope that helps

Thanks It seems fog works better with small scenes. We have an 8 mile city and trying to have fog far away but keep getting flat milky fog everywhere. Also we set medium radius to around 8000 (we tried lower settings too) since you guys said it should be same size as the scene. As far as density 0.01 is the highest it can go otherwise it will be a black screen.

We are trying to achieve similar look like in Zootopia. I guess they used real vdb for fog.

Can you add a spinner called 0 fog zone from the camera to whatever distance we set it too?

Hi coilbook,
I'm sending to developers my opionion about and asking them for a small new feature that should solve this issue.

Thanks!
I also noticed when a camera tilts down just a little bit even though it is still near the ground fog shows up everywhere

Hi coilbook,

Thank you for the post.
Could you help us share a sample scene for us to investigate?

Try using "Octane Schlick" node in the "Phase" pin to change front or the back scattering.

As you have already mentioned you might need a VDB fog in order to achieve the look from Zootopia or some other ways.
