Do we have any thing similar like wavelet in FumeFx to get detail out of our fire in pyro.
It's called Up rez stage, use the shelf tools to “Up rez” your pyro sim.

thx alejandro :roll:
i have another question regarding transparency in fire render when i placed it with black background it looks ok but when it comes to white or bright background it start giving transparency , increasing its values pulls highlights rather than overall density of fire , any solution?

I have found the wavelet stuff in the upres node much easier to control than fumeFX's too 
As for flames over a bright background you have the problem when you dont want to just use additive to comp, you probably want to add an alpha (which you can fake by just bringing in the luminosity of the flames into the alpha in nuke, then grade the alpha to taste). We had a lot of these issues on Ghost Rider 2 and most were solved by introducing/blending in an alpha to the flames.
