Octane's fire looks strange

[cb LLC]

Hi Why does octane fire that simmed in phoenix always looks bad. I attached images of octane fire and your vray rendered fire. maybe at the source where wood burns it is solid flame for some reason. Are there any tricks or that's how GPU renderers render vdbs Thanks

By the way I used Buffered multi pass with 3 SPF

you are rendering fire+smoke, but the vray render is fire only, i think if you just disable the smoke the result will be like in vray, or at least would be a good start for approaching the same result.

Thanks. Anyway to decrease smoke density. I think with GPU rendering we cannot use volumetric options. How does vray gpu work then?


Also do you know by any chance what it means. It shows up in octane log. They don't know especially this c:\jenkins3\workspace

Hey,

Can't seem to reproduce this message - looks like something that's coming out of Octane, doesn't seem to be related to our code.

V-Ray GPU supports the Phoenix Volumetric options so you have full control on how to treat the smoke and fire.

It's best to reach out to the Octane guys and ask them for help.
