Hi,
If I animate phoenix temperature down to where only smoke is visible smoke catches on fire even more

Thank you for the scene !
It had me scratch my head a bit !
The problem basically comes from the inverted Volume Ramp texture in the Emission ramp.
The color on the left should be dark, and color on the right the most bright.
Another issue is on the texture emission power; I changed from 10 to 0.01
So the Emiss. scale now works fine:
Note: the temperature values created from Phoenix are quite high, (up to ~2000.0), that's why the emission power should be small..
Hint: we can see the max value of each channel from the Octane Graph viewer, while rendering in Octane viewport, and selecting the Volume node:
for example, on frame 21, there's '131 x 179 x 107, 2509043 voxels, max abs/scat/emis: 1 / 1 / 2000
Thanks

Thank you! Do you guys have any plans to simplify the way octane renders flames? It seems that there are too many repetitive settings in texture emission, ramp emission, and octane volume modifier. Gets confusing
