nCloth problem

Introduction to Maya - Rendering in Arnold

This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

I'm trying a fairly simple thing (so I thought); drop a sphere onto a piece of cloth, which is constraint at it's outer edges.. Butg the sphere doesn't seem to react to the cloth-object (I made the sphere a passive collider, and attached gravity to it...

example playblast:

It seems so simple, can anyone help me?

thanx

You need to adjust the tolerance of the cloth settings at the moment the sphere is ripping through the fabric. Try adjusting the stiiffness and thinkness to get it right.

The scene look ok and the cloth is reacting well, but needs some tweeking to stop it ripping and react the the ball... Try reducing the mass of the sphere as another option.

ahhhh...

no....

just watched it again... Its passing straight through....

there are settings for the tolerance of how far objects are away when the cloth reacts... in fact it will be on both, adjust those. I cant tell you where as I am at work atm...

Thank you,
I lowered the mass of the sphere quite a bit...
And I tried playing around with thickness, ridgity, stretch resistance of the cloth, but still penetrates... Should I just go for rigid/softbodies?

Kinda weird; you can drop cloth on passive colliders, no problem. But dropping stuff on your cloth object causes problems.. I MUST be overlooking something..

If anyone got other suggestions.. Please

thnx

OK!
I made the sphere an nCloth object and increased the rigidity, and it works sweet! Seems that creating a passive collider and then attach gravity to it automatically makes it a regular rigidbody...

cheers
