Technical Details & Implementation

RTT Architecture

Groups are rendered into a texture using a separate camera and RenderLayer. EmbedClipMaterial handles the rectangular clipping.

The AM Rotation Bug

In AM, rotated groups have incorrect clipping bounds (expanding into a square). bevy_alight_motion fixes this by maintaining correct rectangular clipping regardless of rotation.
