Hi gang. I’m an XSI TD on a maya project, and have a situation which comes up pretty often in FX so I know there’s got to be an established workflow, but I’ve a total of 6 days in Maya so it’s eluding me…

I have a simulation (which I need to keep live) that now needs to be attached to a fast moving object. How can I carry the local transforms of my sim thru world space without smearing particles along the path of travel?

I assume there is some way to pipe my transformation matrix from my fast-moving parent object into my sim? Or is there a more direct solution?

Got some help from 3dPro… for archival purposes, here’s the deal…

You can use a parent constraint on the particle system transform node and correctly inherit it’s transforms, however on a fast moving object emissions can “lag” causing the undesired “smearing along motion path” look. Dynamic oversampling can correct this and properly perform the sub-frame emissions, at (of course) the cost of speed.
