The CustomRotator function allows you to rotate a texture. However, it stands apart from the basic Rotator expression node in that it exposes a center point around which the image rotates. It also changes the rotation system to be 0-1 based, so that a value of 1 is considered a complete rotation, or 360 degrees. On a standard Rotator, a complete rotation requires a Time input of approximately 25.1.
Takes in the existing coordinates for the texture.
Rotation Center (Vector2)
Location in texture space 0-1 that serves as the center of rotation.
Rotation Angle (0-1) (Scalar)
Rotation of the image in 0-1 format, with 1 being a full rotation.
