Never used fog before but am hoping it might add a little realism/depth to my exterior visuals.

Is there a simple way of doing it?
Looked at the Octane manual and it gets complex pretty quickly.

If I need a VDB file where do I get one?

Hello Rik,
you can create your cloud .vdb using Sculptron 1.0

Thanks Paride

Way more complex than I needed though. Just wanted a little haze/fog to subtly add depth to my scenes.

Worked it out from a C4D you tube vid. Is there nothing in the 3ds Max literature? Couldn't see anything.

Used the medium node in my texture environment. Still pretty flakey, unintuitive and hard to control though. Having to faff with the camera gamma settings. Is there a setting for how far from the camera the fog starts (like in max around 15 years ago)

Hi Rik,
you could use a fog cube to adjust how far from camera the fog will start.

I'm just getting a white box.
Is the scattering node in the medium slot of a diffuse object applied to the cube?

Sorry, using max r14 so cant open your scene.


Edit:

Ahh, specular material, not diffuse. Of course.

Like the other guy, I couldn't get rid of the line at the start of my fog box.
So if I use fog at all it will be in the medium node of my environment, though the increase in noise/render time is making even that unlikely.

Hi Rik,
here 2014.max

Thanks for the r14 file.

I get the same line as the other chap so not sure how you managed to avoid it?

Am using 4.02.1 -6.14

Hi Rik,
Specular material > check "fake shadow" option.

Thanks. That's better.

Is there a way to exclude the background from fog or is it a case of don't have a background and add it in photoshop?

I think otoy is not interested in creating nice atmospherics. OCtane fog is just flat looking fog. They need to add a limiter where we have no fog upfront for so many meters and then fog. I am not sure why they just ignore our requests
