Turbulence FD with Octane Tag

[atoyuser1]

Hi,
you need to change the Absorption/Scattering channel to Temperature, now it is set to Density.
And change the Absorption and Scattering color from Black to White:

This works for me, thanks!

Is there a trick for getting it closer to the physical render?:

Physical vs Octane

EDIT: Lowering the Volume Step Length seems to help brighten it, but still a bit washed out:

Physical vs Octane

Hi,
try also to fine tune the Colors in the Emission Volume Ramp, and increase the Max Value, or Power of Emission node.

Thanks Beppe,

Interestingly, if you copy and paste the gradient from the TFD object onto the Object Tag, you get this (on right):

copy and paste the gradient

But it's very red.
The closet I can get is by deleting the red and adding a Yellow to White Gradient, with Max Val 1:

Yellow to White Gradient

But it's still not quite there, the Physical render looks much nicer:

Try making your Max value 10,000

Thanks for replying jayroth2020, that made it red tint:

Max value 10000 yellow white grad

So I tried using pasting grad from the TFD object, but it vanishes:

Max value 10000 TFD grad

Feels like TFD is better suited for smoke than fire, at least in Octane. It just looks like fire-coloured smoke

Incidentally, I might point out that the white in that gradient is actually orange:

White is actually orange

No idea why it's doing that
