How to set scale across all blender objects and keyframes? I have a complex scene with physics (not baked) and I discovered a long way into the scene that I need to scale everything up for the physics to do it's thing right. I scaled everything up, pressed play and everything went to crap. My keyframes are interfering. Is there a way to set the scale of all of the objects across all of the keyframes without messing up the other keyframe settings?
Set the scale to the value you need and all the scale keyframes will be updated accordingly :

import bpy

scale = 2     #change this value  'scaling factor'

for action in  bpy.data.actions :
    for fcurve in action.fcurves :
        if fcurve.data_path == 'scale':
            for p in fcurve.keyframe_points :
                p.co[1] *= scale
