Hi friends,

I'm doing a tree simulation with rbd. But the constraints is way too soft.

The s@constraint_type is “all” and use Hard Constraint Relationship.
I know increase constraint number maybe can help, but there is already 20,000+ constraints and result was still softy.
So I'm wander if we have a way can make it more stronger without increase the constraint number .

About my setting: I scatter point on those pieces and connect them by Connect Adjacent Piece sop,
and use primitive to scale them so the @restlength all is zero.
Sorry I could not upload the scene file. It's our currently project scene.

Thanks!

Have you tried increasing the number of constraint solver iterations?
