set active rigid bodies with an expression


coclea

Recommended Posts

I would like my rigid bodies to become active depending on their distance to the origin.

I tried several things:

a RBD Keyframe active with an expression in the active value like:

dopoption($DOPNET, $OBJID, "Geometry", "P")< 0.1*$F

 

I have tried packed geometry, a sop solver with a wrangler attribute like in "Houdini 13 Master Classes Bullet" but I don't get the expected result: the last pieces emitted are very slow.

 

I would rather have it working with RBDFracturedObject rather than rbdPackedObjet for export reason.

 

How shall I do?
