Hi there,

For an important theater show I must render a dragon spitting fire simulation,
I have a part of the .VDB here :
julienbach.de/files/SpitFire.7z

But I can't get the shading right, I did many tuts embergen/octane,
and i never get the nice shading, i just get ugly overburned stuff and crazy extreme gradient values to get anything its depressing...

I just need it to look like good normal basic flames with a little bit of smoke like the embergen viewport here :
julienbach.de/files/SpitFire04.mp4

Can someone help me and try and if you get something close to send me the material ?!
That'd be super helpful, im stuck with a very bad look and my deadline is close

Hi,
please try with this version, and play with max Value in Volume Gradient node in Emission, and with Scatter value, to have more or less smoke: ciao,
Beppe

Thank you Beppe for your quick reaction !
At least something thats looks like a fire shows up in the viewport...
Now I can't get it the other way around, like in the embergen example : its currently the aged part of the fire that gets emissive where it should be smoke, and its the young part that shouldbe flame-ish that looks like smoke...
Can't get it around by flipping the gradient... What a mess that thing is its driving me crazy >.<
By any chance, can you have something that just look like a normal flaming stream and not like some gaz explosion ?! (like in the embergen example ??
Im sorry but i've been trying hard for some time and just never got anything better these settings are really counter intuitive.

Alright,
so see in the picture here ,
whatever how i play with emissive gradient, it affects the tail, the smoke part...



I neet the blowtorch to be like fire, like this :

and its just immossible to get anything near...
what do I get wrong ?!

Allright,
thanks for the effort !
But these are all too smokey and not flamey , especially at the source...
This effect is important to get right,
at the end I tried with redshift and (unfortunately) got a much closer look... without headache.
it still sucks compared to the Embergen sim though...
