Volume Builder + Shader Field for rolling fog


#1

I’ve got a nice fog look going using a shader field with a noise in it childed to a volume builder.

The problem I’m having is the noise is not moving through the volume at all even though I’ve got a movement vector in place (-20, 0, -20) and speed set (I’ve tried values from 1% to 200%)

How does one get a noise texture to move inside a volume builder?

I also just tried by using the “animation speed” parameter. It clearly animates in the texture preview (inside the noise shader) But does not animate inside the volume.


#3

you have to check anim within shader field options then set speed within the noise …


#4

ha! I was just coming back to post that I had found that. Has that always been there? I feel like in R19 and earlier we didn’t need to check that.

Thanks!

R19 and earlier didn´t have fields :slight_smile:


#6

hahaha. You are right. I was thinking it was inside the noise shader. I see now it is in the field.

I clearly need more coffee or better meds. haha

I’d love to see a render of your fog using volumes. Sounds neat! I’ve gotta find time to get into volumes.

Interestingly, after a full day working through different fog setups and getting just the right look, my client has decided to not have fog in the shot.

All I can do is laugh at this point! haha

When I get her approval on the look, I’ll clear the scene out to just the fog and render a pass of that for you to check out.
