I am trying to make a clothing simulation, but I’m finding that the animation playback lags quite a lot once I make the shirt collide with the character’s mesh. My computer runs on 32 gigabytes of RAM and has an Intel Core I5 GPU. Any advice on speeding up playback would be greatly appreciated.
Bake your cloth simulation. Blender is not a game engine and cloth simulation is not a realtime basic cloth simulation like game engines.
