Chaos clothing tool collision setup

I can’t find the right setup to get cloth simulation working with capsule collision. There’s no documentation for the new chaos system, and the old workflow doesn’t work. I manage to get cloth simulating, but whatever I do, it never collides with capsules, or it only does so (badly) when scaling them enormously.

In the content example project there are two simulations displaying cloth collision, which means there is a correct way to set it up, but I can’t find anything at all about it and I can’t replicate it with a new asset.

Does anyone have any insight on this?


Here’s the way the basic example inside the content example project looks like. There’s a sphere collision capsule and the cloth sim rightly picks it up when simulating.

I found out that exporting fbx format from Blender messes up the sizes and using obj cloth collision works correctly. Anyone knows what’s causing this? What are the correct Blender settings for Unreal?

Hello @hale326, I had a lot of issue transferring models back and forth between blender and unreal due to issues such as that. I found that once I started using the “Send to Unreal” plugin provided by epic games it solved most of my issues. Below is a link to both the original release article and the official github page. In order to access the github page you need to link your github account to your epic games account. All the instructions are contained in the provided article and on the github page. Hope this helps.

That’s good to know, I’m aware of the plugin’s existence, just never used it much. I’ll give it a try, thank you!
