Hello

I am currently working on a project where spheres created from MASH are bouncing around. Each sphere has it's own shader. I want to bake the animation and have a performance friendly animated mesh i can reassign shaders to each sphere. I tried alembic cache but i lose object ID afterwards. It seems to be such a simple task but i can't put my head around it

Could someone run me through a viable process?

Thanks in advance!
