Turbulence Noise Scale

[jlelievre]

Maybe this is the way FumeFX is supposed to work but I have not noticed this until today. If I have a FumeFX container, say 500x500x500 and and I set the Turbulence to a scale of 50, if I then copy that container, set it to 1000x1000x1000, the scale divides in half? The value is the same in both containers, but the preview window is showing me two different noise patterns. I prepped a little video linked below to showcase what I mean. In my scene, I have 2 containers. one small, and one bigger; both have the same turb values but the preview windows shows different scaling of the pattern. When I render out both containers, the larger container has a higher frequency noise pattern.

After simming out a few more passes using different sized containers there doesn't seem any issue. I just never realized this was the way Fume worked!

Hello,

The noise scale will remain the same - it is in world units and the container size does not change it - the ffect is only on the display.
When you enlarge the grid and display the noise in the same image control, it will appear smaller.

I hope this helps.
