New Quick Tutorial - Cloth and PhysX Intro
#1
G'Day

Just a quick video on Cloth and PhysX interaction and also versus other collision methods.

Enjoy

These are very cool Rob.

One thing you might want to explore is setting PhysX Cloth, then on top of this, simulating regular cloth so you can get more details.
I wrote in the Facebook group more about it:

But I didn't had time to test further at the moment, and then later.. I forgot about it.. lol.

Thanks mate, will look into it

I Looked at it, I don't get what you are suggesting to me from that file.  Did you see my video until the very end?  Where the cloth lands on a PhysX Sphere and then falls and the PhysX sphere runs over the cloth, on the animation with the covered logs falling and interacting with the cloth as the logs roll off.

They are two way interacting there - but fairly simpler flow diagram.

Just wanted to suggest you to further explore the possibility (if you want).
So let's take your example from the far right (the blue one)... or the animation tests at the end...
It's all PhysX right?
Both cloth and the rigid bodies.

Now, after you do that PhysX sim... imagine you cache the cloth.
Then you add like turbosmooth x 2 on that cloth.
Then you create completely new flow, where you birth object (cloth), give it a Cuda cloth, and then grab some random vertices to follow (with object bind) original cloth sim done with physX.
That way you will get another cloth sim, but much more detailed then PhysX one.
The PhysX cloths are always (in my eyes) a bit too rigid, and they tend to jitter.... I've never succeed making with them something like silk, with lots of fine wrinkles.

I hope it makes sense.

It's just like an additional pass for PhysX cloth, so the cloth looks nicer.
And it's probably not going to work in every scenario.
