UE4 Cloth Simulation does not see collisions

Hi,

I have a cloak on my character which should behave like a real cloak. I watched some guides to cloth simulation and did everything they did, and it works only to 50%. It simulates cloth, but doesnt collide with shapes I created in Physics Asset (using tapered shapes (only for clothing)).

Here I am in PA simulating with an animation, you can see that these shapes are clipping through the cloak:

And here is in game behaviour:

Why is it not working and what could be the problem? How do I fix it?

Depends on engine version.
UE4/5 without Chaos - never works with external collisions. Only internal PHAT.
UE4/5 With Chaos - May work with both.

Make sure you have the Phat asset assigned to the cloth.
There’s a hard limit to how many collisions affect cloth. And realistically, if on PhysX you should download and build the ApexTools from scratch.

Unfortunatly I dont understand what I should do with the information you provided me with.

I have Physics Asset assigned to the cloth:

I made shapes in this Physics Asset:

Cloth gives 0 collides about these shapes. Cloth does not collide at all.
This is what every guider on YT did and it works in his project, but not in mine.
Why?

I use UE4-26. Maybe I have something disabled?
