Unreal Engine – Cloth Solver

I spent the weekend writing a cloth solver for Unreal Engine 4 after being inspired by the cloth placement tool I saw for Source 2’s Hammer editor.

Spent the day writing a cloth solver which can run in the editor in @UnrealEngine
Maybe will make this into a tool which stays as a static mesh at runtime? Need to rewrite the solver in compute first though! #techart #UnrealEngine #gameart #gamedev pic.twitter.com/Gl1AqkcGaI

Currently it runs on the CPU & will generate its own primitive scene proxy to calculate the mesh on the render thread from the particle simulation.
It also collides with the scene in real time – works a lot better than I was expecting!

I am contemplating releasing this as a plugin for the marketplace, until then here are my plans:

• Improve stability (ensure assert conditions won’t be hit as much as possible)
• Double-check performance & provide CPU profiling stats akin to the CableComponent plugin
• Move solver to GPU with a compute shader
• Optional GPU scene depth collision
