How to apply motion blur to particle volume effects in post?

[ActionArt]

I admit I'm not the best compositor and sometimes the various buffers/options etc. tend get me confused

Does anyone know how to take and ICE particle simulation using the particle volume shader (a smoke effect) and output the right frame buffers and apply motion blur in post? There doesn't seem to be much documentation on it.

Can it be done in the FX tree or Toxic (the one the comes with SI)? I don't see a motion blur node in either. I don't have Nuke or anything like that.

Thanks for any help!

i dont think you can do that in a simply way, personally when i've tried nothing worked at all, i have no idea how to achieve that, especially using the particle volume shader, motion vector from mental ray doesnt read them, maybe wait for some more experienced user, but everything i've tried failed bad.

good luck

Dang. I guess it's no wonder I'm confused as nothing actually works it seems. I didn't think it was going to be this hard.

It was suggested on the list that Realsmart motion blur was the answer. I didn't want to buy something just for that but I guess I'll have to check it out.

Anyone? Ideas?

you can download it for free and it works with a red cross watermark but at least you can see if its worth and its workflow.

anyway there probably should be a way to do this with softimage, too bad i dont know it

I don't know if this will help your needs, but Eric Mootz released emRPC4 that has MB in there...

I use the FX Tree a lot, I guess it depends on the directions of your particles and the simplicity of the effect you are looking for, also the quality of the end result. I haven't tried this with particles, but if you have more of a linear motion you might be able to get by with animating one of the post blur effects and combining that with the original footage on top (over or math node should work) - again, not a great suggestion on my end, but if you only need something quick, and can pass for the quality you are looking for, that might be an option.

Unfortunately, it's a fairly complex 3D motion effect I'm looking for which is hard to do that way. I should mention too that it's a still image so anything that might work in Photoshop would be fine too. As a last resort I'll have to do it manually but it's difficult as each particle is moving a slightly different direction.
