Hi, I've been modelling in XSI for a long time now, but I'm just starting to learn animation. I've created a very quick and dirty animation using parent objects and keyable paramaters (I think that's the right term? Its the little green box found to the left of many options.) Anyway, my animation works as expected in XSI…
What parameters did you keyframe, exactly? Not every option will be transferable to an FBX. Scale/Rotation/Translation should be safe bets, but I wouldn't count on any other parameters.
Extrusion along curve start and end position. I guess it would make sense that wouldn't carry over since its kind of specific. It's too bad since the keyable paramaters are so cool and intuitive to use
