Hi all, I need to load fire from embergen, when I set absorption mapping and scatter mapping to density and emission mapping to flames (as it should be) then nothing happens, literally, but if you change everywhere density to flames then everything starts to be displayed, but not as it should be because the density areas start to glow, tell me what could be the problem and how to do it more correctly, I attach screenshots of how it looks in embergen and in octane.

Hi,
please share a screenshot from Octane Volume Medium node, and from Embergen color gradient of the fire.

Basically you need to recreate a similar gradient in Octane Volume Medium node.

The problem is not getting a similar look in color but getting the same detail, for some reason some flames are missing, the overall detail in octane looks pretty mediocre. Perhaps you can try to check how it looks on a single vdb frame? It would be very much appreciated

Sorry, but the vdb file you have shared seems not correct here.

Could you share another one?

Anyway trust me, the more variations you add to the emissive Volume Gradient in octane, the more details you can have.

Please also share a screenshot from Embergen similar to this one: ciao,

If it is of any help, this demo is using the free EmberGen demo files: and is from this page

"Colors" must not be matched to EmberGen in the sense that the two software (Octane and EmBerGen) are not identically color managed or built on the same "rendering code".
