Blender Addon - Blenderer

This is more of a Blender question, but does anyone have a solution for updating all object animations in Blender while keeping the meshes as they are?

The reason for my question is that for bigger projects it’s often time consuming to re-render the entire simulation. Also, I often do some material tweaking etc. in Blender so I would really like to keep as much as possible of the scene and just update the animations.

For armature animations it seems fairly possible to link animation data/copy keyframes between objects, but for node animations I can’t really come up with a solution. Also, finding a way to batch replace is essential, since manual replacement is no option.
