Hi,

This thread appears to come up fairly often after I completed a fairly lengthy search of the forum archives but many of the results were never finally discussed so I’m hoping this time around I can get some solutions. I also posted this into a Maya section simply because Maya is the 3D tool being used (hasn’t been double posted).

I'm about to start working on a project that requires thruster exhaust effects from a missile (that being both the ejection exhaust and smoke plume). Some users have suggested I look at RealFlow but not sure if this is really necessary. Dynamics are certainly not a strong point of mine so I envisage a lot of initial work to get the desired affect but really need a good solid grounding in the right direction to start with. I’m looking for any training material that could assist us in developing this shot. The camera is intended to be rather close at ignition so we are looking for a detailed solution.

This is what we are trying to achieve:

My client is wanting something as close to photoreal as possible. It will eventually be composited onto a live plate. We do have a budget for some training material if required so if anyone has any suggestions it would be greatly appreciated. In addition to any comments on if RF4 could be of advantage.

Thank you to anyone that can provide some help.

Regards,

Nick.

this is more a particle or compositing question than a modeling one.

I would agree... the built in particle sims are decent, but if you need something up close-realistic, real flow might be something you would like.

Hi!

it's better if you post this question in an effects/compositing section, particles are not considered modeling anyway.

Good luck with it and please show us the result!

This tutorial may help a bit on the particle effect, and texturing...

As for the gather at the bottom just create a Deflector for your particle system
Space warps > Deflectors
Just don't forget to bind it to your particle effect :D

Also you may want to use smoke as a displacement map on your particles... although that will be extremely nasty memory wise :D
