FEM Alembic - Angular Velocity not Centered

Recommended Posts

Sup guys,

I've just imported an alembic from a client - it's just a static object - and it's already placed a few units up from the ground.

I need to give it some initial angular velocity to make it spin while it falls but, it looks like, the angular veocity is coming from the origin gnomon.

I'm not able to publish the original file but I did a very similar setup (attached)

I'm also not in a huge hurry about this (just got a file with the object at the center of the scene, now i can translate it manually) but I would be happy to know how to fix it. 

Cheers,

cant really help without the alembic file. but I assume that dops does not know the center of gravity. you could fill out the pivot parameter in the initial state tab with the centroid() expression.

centroid(opinputpath("/obj/sphere_object1/dopimport1", 0),D_X), centroid(opinputpath("/obj/sphere_object1/dopimport1", 0),D_Y), centroid(opinputpath("/obj/sphere_object1/dopimport1", 0),D_Z),

 

good luck
