I’m unfamiliar with the Clothing Tool, and APEX cloth. And the Cloth Examples map is in one of the main folders of the engine, either Content or Engine Content. Do a search for “cloth” in the content browser search bar when in one of those folders and should be able to find it.
Here’s a link to the doc page, specifically a reference of the Config properties:
It’s quite a bit of properties to adjust for creating exact effects. I suggest searching for a tutorial that illustrates how at least a few of those properties affect a two-sided cloth, specifically a cloth type that is similar to or the same as a towel. YouTube has a ton of tutorial videos for UE4, so starting there might be the best option.
If I understood correctly you want to simulate cloth on a model that has thickness?
You can do that with PhysicsMesh. It’s basically just another model (usually a plane) inside, that is roughly of the same shape as your original mesh (or GraphicsMesh). You need to create your cloth simulation on that plane but apply cloth to your original mesh. This way your GraphicsMesh will follow the simulation on your PhysicsMesh. You can then disable material on the PhysicsMesh, to get it out of the view.
Interesting. Two-sided in the cloth’s material or in the cloth’s mesh details? There’s two-sided shadowing, two-sided lighting in Lightmass settings for a mesh, and two-sided for materials, lol. What one was unset?
