The exported clips and backdrop movies were drawn source-over everywhere, but the cabinet places a number of glow layers with its add blend mode: the lantern glows of the lower backdrops (bg_nomal_a_01..05), the crown's radial burst, the score rank plate's effect copy, and the full-combo / donderful letter glows. Drawn source-over, those textures show up as dark or grey patches. - movie_export / clip_export record the placement's blend mode (`blend = 8` on a backdrop leaf, an 8th row value on a clip leaf; the root placement's mode is folded into its group), and bg_anim / clip_player / ending draw such leaves with blend = "additive". Data re-exported; only the blend field changed. - result_crown: the burst copies draw additively; the crown_loop shine sweep is a plain white polygon on the cabinet, so gleam frames 0..2 are white now instead of the atlas colour they were exported with.
