Hi, i wish somebody as done this before.. And post here an sample scene.. maybe tweaking the blast preset from the maya fluids preset.. I have half luky with the 1st part of the eruption.. but when the smoky body reach the top i can't figure out how to fill the sky with the head of the column... Understand? I've increased the size of the emitter but all the stuff already emitted increase with him..

Here is a Playblast (http://www.elvis64k.com/video/blast_Top.avi) ..14Mb (too big file sorry)
The shot is from the top and is for the next part of the animation.. when the stuff loose energy and falls down slowely..

To collapse the half part of the body slovely down... I've tried to use gravity field but the fluffy smoke became too softy like wadding.. I've not tried yet to move down the emitter becouse of time consuming with rendering...

This is the first shot and all work great..

Hope all is clear. Thanks!

ok... at end of the day...

Nobody loves elvis.. I know about my bad language..

If nobody can help me, maybe somebody can post here some eruption stuff (maybe some preset to use). Fluid is a dramatic part of maya and Alias tutorial is not enough.. Tweak the settings take a lot of time and we all know that some time we prefer to fake a vfx with sw like digital Fusion and Combustion...

Why all we waste the money for a fluid dynamic not dynamic enough??

gotta play with the settings. Also, you can add an emitter specifically for the spread. Not all particle jobs consist of a single emitter. Some emitters have a specific purpose.

Thanks to open that door pixelmonk!! Indeed you save me.. Can you explain more about emitter's job?? Thanks anyway...

well.. when I say "job", I mean the particle's purpose in the scene. For instance... you can have one emitter used for creating the volume shooting out of the volcano. You can have one or two others in the sky, angled out to the sides creating the dissipation of the volcanic ash away from the volcano.

I had to create around 4 emitters for a missile launch in Lightwave (last year) in order to get the right look.
