Is there a way to bake simulations? .For 2 reasons,
a) , I want to make use of rendering different passes for compositing on the same sim, depth pass, ect, and
b) Export the simulation to fbx for use in another 3d app, currently I get the meshes exported but no anim data.

Hi @user50857! I need a bit of clarification so that I can direct your questions to the right person! What type of simulation are you referring to? Are you referring to Isaac Sim, Physics, Animations or something else?

Thank you for your reply.
I have a simple physics scene with deformable body added to some blood cell and platelet models falling onto a ground plane. My problem is every time I press play I get a different result from the simulation, was just looking for a solution to bake the animation.
Kind regards.
