Is there an easy way to, while keeping all of the physics settings the same, turn off the physics processing? Essentially, I have a huge scene with a ton of physics and I'm not ready to bake it yet but with all of these simulations going at the same time, workflow has slowed to a crawl. I want to tell blender to just process the simulation I'm currently working on but without it messing up my other physics! Any ideas?
Yes, click the eye icon in the physics panel or the modifiers panel to disable the simulation in the viewport:
Clicking the camera icon disables the simulation in the render.
