MK1 - Environment Cloth Simulations

Cloth simulations were added to a variety of MK1 environments to keep things lively where procedural WPO methods weren't quite enough.

The workflow for this type of sim was pretty streamlined and needed very little manual adjustments, mostly to cut out holes that are present in the material but not the mesh itself (I probably could have done this procedurally as well but it was quick enough to do for the amount of flags that needed to be simmed). Some flags had tassels attached at the base that were simmed as shrinkwrapped stiff cloth that were used to deform the original mesh. The loops are 150 frames long and were created using the "MakeLoops" SideFX labs node, easy enough!

It took a few iterations to find the best solution for getting simulated loops of cloth into Unreal and after testing Geometry caches extensively, the performance impacts were way too high so I fell back to tried and true VATs. The SideFX Labs tools in Houdini have made it much easier to export VATs and the material functions in the SideFX Unreal plugin were used to apply the movement in engine.
