I'm a bit (or more...) lost about keyframes and fcurves information even if I have read this question and answers or others and tried to understand the related documentation.
What I'm trying to do is the following:
- Looping along frames which have keyframes set on them (only these frames)
- For each keyframe retrieve the related keyed objects (I'm interested in objects and bones only) and retrieve the keyframe information (location, rotation or scale only)
How to do that in Python?
