When frame is switching from 5 to 6, red monkey weirdly flips and green rotates well. Red one is using empty's X rot Transform space as variable. Green - empty's data path of X rot.
Empty is keyframed for all rotation channels and it seems that Driver is mixing them like as World space
You can see how drastically driver value has changed (from 2.896 to -0.246), while empty was barely rotating
Is it a normal behaviour? And should I always stick to data path connection for driver in similiar cases?
