Hi!
The standart TFD render speeds are below all acceptable limits. Octane does it extremely fast, but... There's two questions!
TFD render has vectror desplacement features that help to make low resolution simulation more realistic, Octane, of cource. no. How to add some similar vector displacent to octane render to mimic those small flame features and "sell" picture better?
Also, I have major difficulty setting up realistic flame shader, I don't really get how to do it. And there's not much info about it. Also, how to differentiate smoke and flame isn't clear enough too...
Can you help me with some tutorials? I didn't find any good info about that all, will be greateful for your help :)

Crash ended on TFD side. I can't help for that. Where it happen? Any scene to share?

Here is manual:

You can use "use motion blur" parameter if you have velocity channel. And you may need to increase "velocity scale".

This is my test scene

Motion blur via velocity channel is not really what I meant. Velocity displacement distorts image and adds fine details, not blur it

It's way how Octane does it. Do you look for somethings better than this sample?

Oh! Blackbody emission instead of texture emission! That's what is the key, thank you!
