TerrainLayerSettings

Remarks

[docs/plan/31 § The terrain panel]: the paint channels the terrain's layer list declares, each with its coverage, an assign control for the .vxlayer, and a weight-blended toggle. Selecting one makes it the paint target — which is Target, and the tools are the strip.

⚠ The layer being painted changes far more often than the tool, so the list is above the strip and not in it. That is Unreal's layout and it is correct: an artist paints grass, then rock, then grass again with the same tool, and a design that made the layer a mode would make that three mode switches.
