After Effects composes a 3D layer's (and a camera's) Orientation and its X/Y/Z Rotation as Rx * Ry * Rz each, Orientation before the axis rotations; EffectCraft used Rz * Ry * Rx. Measured on synthetic AE 2026 cases: Orientation [10,20,30] (488) was 5.2 % of the frame off and now matches to the anti-aliased edge (0.03 %); X/Y/Z Rotation 10/20/30 (800), Orientation + X Rotation (801) and one-node cameras (804, 805) likewise. Keyed Orientation moves along the shortest arc between the keys (quaternion slerp, eased in time, angles written in [0, 360)): keys [0,0,0] -> [10,20,30] read back [6.2643, 9.3531, 15.2190] half-way where EffectCraft gave [5,10,15]; [0,0,0] -> [60,80,40] linear and eased match AE's read-backs within 0.002 deg. lookAt() returns AE's angles (z axis on the target, x axis level; two AE read-backs within 1e-3 deg). The camera tracker, VR editor, Look At and orbit commands use the new decomposition. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
