How to get smooth falloff?

Maya
1

I am working on a battle sequence where i have to generate a lot of smoke.
The problem i am facing is i don't get a smooth fall off towards the end of the smoke because i am using opacity texture to get details, i have tried using the y gradient in the dropoff shape but still it doesn't help, i even tried using a ramp in the frequency it dosen't help either.
Please can some one help me on how to go about it?
Thanks

maybe a high edgeDropoff (in the shading tab) might do the trick.

hi dave
thanks for the info
but that doesn't help
because you still get that noise banding in the end
is there anyother solution?

I'm not a pro, but you may find the following useful . . .

Try tweakng the Shading>Opacity tab for the smooth drop-off you'r seeking. Play around with the input bias, leave the input opacity to density driven.

And you may find the following tips usefull 2:

And as for the color and incandencens make them density driven too tweak the colors and input biases -you may first tweak using basic colors and then head to linking cluod shaders and blenders- .

Also carefully texture the incandescence, you'll be amazed what this can do. Hope this may help. goodLuck
