Good luck to everyone.
Hope we can all learn with this experience.

It's not easy to get that nuke look but I'm trying to do so.

I'm still trying to make it going up but it's not easy.
If someone as some tips, it would be awesome if it could share.

Really need to see some video Victor before anyone could give you some tips. So far its looking promising but my guess is it may be a bit small in scale and too fast in simulation rate (wow how do I know all this from just those pictures?)

Sorry, I'll try to post something soon.
I'm very busy at the moment but I promise until the end of the week I'll do something.
Cheers and thanks

Well not the best Nuke but at least a test to start a conversation.
To say the truth this is my first try.
I still need to work hard I know.

(It's a little dark this version so I think it's better you watch in vimeo)

Na its not easy like you say, I wouldnt say you have a nuke there rather more like a nice fuel explosion mainly due to the sim rate being too quick. We've all been there, some of us are still trying to break the hidden secrets of Maya fluids. Keep it coming!

Totally agree with you.
Definitely have to take a good look to that thread.
Thanks
Cheers

Ps - Jeremy take a look at the one in vimeo, the colors are way too different.
Don't know way the codec is exactly the same. I would like to thank you because of you I got to be a beta tester for Fracture. If it wasn't for your website, I would never get to know it, well not exactly but It really helped me to get to know it fast. :beer:

I like the one on Vimeo better, its not as saturated and you can see more detail because of it. Are you texturing the color channel? doesnt look like it and if you are it looks as though your color ramp is one hue, try mixing it up a bit there for more detail.

You're welcome about Fracture, I think its a great plugin. Unfortunately one of the comments by Kevin really pissed me off so I stopped testing a while back now.

Yep I'm texturing it.
Color Tex Gain is 1.000
The colors in the Shading (Color) are (22-0.4-0.2) - brightest area;
(21-0.3-0) - darkest area;
Color input - Temperature
Input Bias - 0.05

That'll be why, normally I use one of the gradients or density to shade colour because after temperature burns out, colour does nothing to your shading and yours is looking quite flat at the end of the sim.

I'm creating a new and I had self shadow and it that flatted smoke looks much better.
Maybe this was what was missing

sorry dude, I didnt understand you there...

I said I activated self shadow in the new fluid test and that last flatted smoke disappeared.
Cheers
