This package implements custom cloth physics for Unity. It runs on the CPU, doing most of the simulation work on a background thread (some main thread cost still applies). It utilizes the Jobs system for partial multithreading - a single cloth object can't be split into multiple threads, but two cloth objects can be simulated at the same time on different threads.

Note that by default, this is a purely visual effect and all physics support only one-way coupling (the cloth will not affect other physics objects). You can implement custom logic that interacts with the cloth. A short introduction to the API is included in API.md

The project contains many issues that would need to be fixed if you want to use it in a production environment. A list of known ones is included in Issues.md. I do not take responsibility for any, and I will not provide support. You are free to use this project as a starting point or a basic learning resource for your own simulation.

See Setup.md for information on how to set up the simulation, and UCClothReference.md for a brief explanation of all parameters.

This repository is a package compatible with UPM. Open the Package Manager window in Unity and click the "plus" icon.
