Maya - Is nRigid heavy?

Yerus

Does nRigid cause heavy calculations by itself or only when interacting with nCloths?

What makes it heavy?

If I for instance have a 100,000 poly mesh as nRigid, but only 50 polys are actually interacting with a lowpoly nCloth.. will the dynamics be heavy? (not talking about polycount, just dynamics)

In a nutshell: when nRigid's mesh interacts it acts like a single force or by its individual componentes?

Thx.

AFAIK everything in nCloth solves per-vertex always. Even if a given vertex isn't interacting with something, it's still part of the calculations and can slow the sim time down.

Yes, nCloth is always heavy, but i'm asking about nRigid.
Does it even calculates anything when there's no nCloth?

nRigid is still in the nucleus family, so it has all the quirks. So if one vertex is colliding, the system still needs to step through all the rest. I'd go in expecting it to be slow.

I don't believe there's a hit from it being there and doing nothing. If it's a problem, you can always have the collider disabled while you work, and enable it when you do need it.
