From f51b4b7e1be5310fab102a8f4d507b33775fdadd Mon Sep 17 00:00:00 2001 From: tylerjenningsw Date: Tue, 13 Oct 2026 10:52:40 -0400 Subject: [PATCH 1/4] Track Matte: set the matte of several layers at once (#1260) layer.setTrackMatte took one layer. It now also takes `layers`, set in one undo step; `layer` and the first selected layer still work as before. `kind: "preserve"` keeps each layer's own matte mode (Alpha for a layer without one), so giving several layers a new matte doesn't turn a mix of Alpha and Luma mattes into one mode; without `kind` the mode is Alpha, as before. A layer can't be its own matte and an empty list is refused, before anything changes.

Each is one undo step. A selected layer chosen as the parent or the matte is left out of the layers it links, and parenting that would make a loop is refused as a whole. A new matte layer keeps each layer's mode (layer.setTrackMatte with kind: preserve); a mode and No Track Matte apply to all of them. The Track Matte column gets a pick whip, like the parent's (timeline.layer..trackMattePickWhip, with a translated tooltip): dropped on an audio-video layer's row, it makes that layer the matte. The layers a parent or matte pick whip links are taken when its drag starts. Tests (ui_batch_links): the Parent menu and pick whip, and the Track Matte menu, mode, No Track Matte and pick whip, with real clicks and drags: selected layers change together and unselected ones don't, modes are kept, one undo puts links, compensated transforms and the matte's visibility back, and a refused cycle changes nothing.
