1 it is pausible to render fume fx in corona with shadow casting + scattering.
How? I've done numerous tests - sure I can light the smoke and get it to cast shadows on other objects, but not self-shadows or proper scattering - because it uses a standard max atmospheric renderer that has no integration with Corona:
FumeFX (changed density to 2.0):

No matter what I do I cant get it to look any different to this. Yes I have added CoronaSun to the lights list. checked/unchecked self shadows etc
PheonixFD Mesh (3cm absorbtion CoronaAtmo material applied):

and 10cm absorbtion:

There is a big difference - I cant even change the smoke colour in FumeFX eg make it lighter.
Perhaps you'd like to share these secrets on how to make FumeFX smoke look more the PheonixFD mesh examples...
2 if the smoke does not look like it should then the point of exercise was not ashived.
It looks like smoke to me. I doesn't look like water or a flock of seagulls or Keith Richards....
3 don't you see by you're self that this is not proper result? if this realy the image that was in you're head when you were doing this?
Obviously I would love to produce a photo-realistic result of a car doing a burnout. Maybe I should actually do some training in the 3D field, but that's a little expensive for just a hobby. I would love to have access to render farms and expensive PC's that can handle more than 30 million particles, but unfortunately I have to make do with what I got, and all things considered my PC is pretty good but hardly anything you'd find in a production office.
Relatively speaking - I think the render is pretty damned good. I have recently upgraded my pc which means I am now actually able to produce and render smoke! With reasonable details too not just puffy transparent clouds.
Maybe one day I'll get to producing realistic burnouts, maybe I'll get bored and move to another hobby, maybe one day a flash of lightning will come down from the sky and zap me and turn me back into a normal person and I could get a job and a house and a car and 2.5 children and a pug dog...
Dreams are free.
PS I'm a petrol head, an old one at that, so I know what a burnout looks like. ;-)
