Soumya Pochiraju (Forest) added a comment to T81957: Particle Systems don't inherit object velocity when emitted on one frame. .

I couldn't find a proper fix, but this patch fixed the problem for the case where objects are emitted in one frame. When the particles are emitted in different frames I think the velocity needs to be calculated using a fraction of the timestep, but I couldn't figure out how to get the correct delta time

Soumya Pochiraju (Forest) added a comment to T91959: Crash (memory use after free) on freeing RigidBody world.

Not sure if this helps but I single stepped through the function and I think RB_world_remove_constraint in the patch is never called because the rigidbody world has already been freed before this function is called. And the constraints are not removed when the rigidbody world is freed (in source/blender/blenkernel/intern/rigidbody.c- BKE_rigidbody_free_world()) because rbw->constraints is set to null at
source/blender/blenkernel/intern/scene.c line 399, but I couldn't understand why that is necessary

@Jeran (Thejeran) Sorry, I haven't had time to work on this so far, but I'll try to do it soon

@Germano Cavalcante (mano-wii) Okay. Thank you for removing the unrelated changes! I will try to implement it by saving the previous location

@Soumya Pochiraju (Forest) can you just manually exclude the changes from libmv from your diff then? What may happen is that you may have a different version of clang-format and make format is changing them.

created diff after syncing with remote and running rebase, I haven't changed the files from inetrn. Don't know why these formatting differences are showing up

I think the psys_get_birth_coords function uses the particles current and previous locations to calculate velocity rather than the object's. But I'm not able to figure out how to access the object's previous location inside of this function.

Hey! I'm a beginner, and I'm trying to work on this. I think I understand what needs to be done, but I can't seem to find where grid_res of the ParticleSettings is being computed. Could anyone guide me on the same?
