The 3 rotation formats in Blueprints - 1) Get Actor Rotation 2) Control Rotation 3) Normalized Rotation

[DavidOConnor]

I honestly just figured this out, but it can be useful to know that UE5 blueprints uses 3 different formats for rotators.

Standard rotation:
Roll: +/- 0 to 180
Pitch: +/- 0 to 90 (this is a bit confusing, but it goes up and back down)
Yaw: +/- 0 to 180

Control rotation:
Roll: 0 to 360
Pitch: 0 to 360
Yaw: 0 to 360

Normalized rotation:
Roll: +/- 0 to 180
Pitch: +/- 0 to 180
Yaw: +/- 0 to 180

This is one reason (among others) that breaking and making rotators needs some caution. Also, I haven’t experimented with this, but mismatching rotator formats may also cause issues when using Combine, Delta, Interpolation, Lerp, etc.

One way to convert your ‘Control rotator’ or ‘Normalized rotator’ to a ‘Standard rotator’ format is to use quaternions… the ‘ToQuaternion (Rotator)’ and ‘ToRotator (Quat)’ nodes in sequence.

I haven’t found a way to convert a ‘Standard rotator’ to a ‘Control rotator’ or a ‘Normalized rotator’… i.e. the other direction.

Anyway, this had me puzzled for ages, so I just thought it might be useful
