Frame 1 / 1 Dur Stopped

x: —, y: —

Hard-cut and fade animation with linear, smoothstep, or tanh shaping. Preview playback always uses local elapsed time. Per-frame duration is measured in timeline units at the current FPS. Mirror XY mode stores only the top-left source quadrant and reconstructs the full sprite in preview and export. Export can use Godot TIME, an external uniform named anim_time, or particle lifetime phase via INSTANCE_CUSTOM.y. Undo: Ctrl+Z. Redo: Ctrl+Shift+Z or Ctrl+Y. TODO: remove unused ifs.
