click a zone name → click islands on the model or the
map to move them in/out (re-click = back to misc). Assigning auto-enables
the zone's tint. paint mode ON or shift+drag sweeps islands;
draw: remove drags islands back out to misc.
mode: rep = replace hue keep shading · add = brighten · mul = dye.
split divides a merged island at UV seams. tex paint = real
pixel brush (layer/atlas/zone-masked, clone-stamp via alt+click).
attachments: +prop GLBs (with their own anims), +light night lamps,
+smoke emitter, +object attach tree/rock/…, +anim node motion — pick one
in the list, place click-sets position, sliders fine-tune, or
drag the gizmo handles on its origin (W/E/R = move/rot/size,
where the kind supports them); the
light picker swaps the whole scene to day/dusk/night (same rig
values as the in-game day-night cycle) so lamps + dark palettes can be
judged in place; producing toggles smoke. save → faction names the
variant <fac>__<name> and registers it on the
faction (buildingVariant / objects pick). publish → vault exports
an ObjSpec kitbash doc to the vault (tbx parts).
