This may sound stupid, but what is the "f-curve" that is talked about. are you just talking about the control handles on keyframe points in the track editor or is it something that I don't know about? Thanks

Function Curves are a graphed curve that represents motion.

On a Function Curve [or animation curve] keyframes are represented as points, curve segments between keys, and tangents that control how curve segments enter and exit a key. These keys are laid out on a graph that displays their position relative to zero. you can have keys that are either positive or negative values.

This visual graph of keyframes allows one to easily see the value of the key, its interpolation to the next key, "ease ins" and "ease outs", and whether or not Euler rotations are giving you any problems...and quickly edit them for your desired result.

[Euler rotations have quickly been replaced by more popular/accurate Quaternion rotations, but Euler is still used - watch out for gimbal lock! :)]

Function Curves... :love: *sigh*

that is what I thought, it was just the way that it was talked about it seemed like it was something that was new to the 3D scene. Cheers
