Camera Axis

Page in progress...

This is the camera axis curve when you animate the camera:

As you can see, the curve is constrained to stay within the range of 180 and -180 because it wraps around and cuts the curve when exceeding these limits. This creates an issue for the camera, as it can produce very heavy motion blur on a single frame when the axis flips from -180 to 180 (or vice versa).

To resolve this, my addon includes a feature called "Fix Camera Axis Flippings" (enabled by default).

When exporting, the addon automatically processes the rotation values and recreates a continuous curve for the camera axes, removing any abrupt cuts caused by the -180 to 180 wrapping. For more detail see fix_transform_axis_flippings() in bfu_camera_data.py

This is the camera axis curve after applying the axis curve fix:
As you can see, the curve now flows continuously from -90 to 630 without any cuts or wrapping issues. This ensures a clean and smooth animation.
