Sim at Origin with Direction Change

[TheDude123]

Hi, I've seen a few people invert transformations of an animated object and then run a simulation at the origin (pop, flip, pyro, etc.). However, when I try to do this with an object that changes direction, it breaks. The simulation doesn't follow the animation as expected. To be fair, I've only seen this done on objects that have a linear motion...point A to point B...think meteor falling.

For reference: https://www.youtube.com/watch?v=9wv88f1kvoY [www.youtube.com] (@ 13:30 mark).

Am I missing something? Does this technique not work with animated objects that change direction?

Thanks for any feedback.

Looks like your logic is broken, try to point deform from straight line to curver after sim is done.

Hi, and thanks for replying.

I don't quite follow, though. Could you elaborate or modify my .hip so I can better understand?

Thanks.

You should fake movement in your sim to makes this work. But this is bad reference for sim in origin. Usually at origin sims some explosions or smokes that scattered after or effect that doesnt depend of motion of the source

Thanks for the reply and the info. I thought the motion of the source wasn't playing nice with this method.
