Ah, OK,

Well, I think there's better news there, but as you know, geografts are inherently 'special', so here's what I think I know.

I believe Gérald's new "Import with Obj files" checkbox in the 'Collision parameters' tab was added to address this need.

Maybe a quick try of the collision-item import with the 'Import with Obj files', 'New animation', and 'Use animation' check-boxes will import and perhaps generate the desired effects.

This is another place where Gérald knows the subtle details and intent, but I'm pretty sure this was part of the inspiration for that check-box. It may slow the frame-to-frame simulation down a second or two (each) for the first run, but should otherwise be pretty low-impact to use this option.

Give it a go with your scene/items and let us know!
