Orrery › Terrain › Editor

Activate the terrain editor mode in the level editor.

Apply one brush stroke as the editor mode's brush tool applies it, as one undoable "Terrain stroke" transaction.

Bake Actor's authoring layer into a new tile store beside its map and re-point the actor at it.

Bake World's terrain, as Manage, Bake does without its dialog (UOrreryTerrainBake::BakeAuthoring).

Python and Blueprint entry: IsImportCurrent as a struct, so a stale store still gives Python its reason.

A click of the active feature tool (Plate, Corridor, FeatureList) or Stamp tool (it places a stamp) at Location_m, world m.

Give the active brush tool Stroke's settings (Stroke.Tool and Path_m are not used), so its ring and HUD show them; Stroke.bInvert holds Shift.

Give the active Stamp tool its settings.

Parse a GeoTIFF without importing it: what v1 would read, or why it would refuse.

A press at From_m, a drag to To_m and a release of the active brush tool (a stroke) or Stamp tool (a stamp centred on From_m whose radius and angle the drag sets), world m, through the mouse's own path.

The active tool's id; empty when none.

The HUD lines the active tool draws this frame (brush, Stamp and feature tools), for scripted checks.

World's terrain actor, the one its terrain was created from; null when it has no terrain.

The level editor's world; null without one (a commandlet).

The terrain's StateHash once pending sculpt bakes are done (the bits of a uint64); 0 without a terrain.

Whether Actor names an authoring asset that still holds a payload: what the cook refuses and the bake commandlet's -Check reports.

Whether World's terrain holds authored edits the bake has not folded in yet: live ones not yet captured, or a captured payload.

Python and Blueprint entry: ImportGeoTiffFiles with the default options and a decimation.

Python and Blueprint entry: ImportHeightmapFile with the default options.

Python and Blueprint entry: ImportLandscapeToStore with the default options, the given paint switch and the hide switch.

Fill a heightmap source asset from a little-endian 16-bit RAW file.

Whether the active Stamp tool has a stamp waiting for its ground (poll it after a click over unloaded ground).

Point every perspective level viewport at the ground under Target_m (world X and Y, m) from Distance_m away, Pitch_deg below the horizon, looking along Yaw_deg; realtime on.

A new-terrain properties object with the user's last values (Manage, New): set its fields, then pass it to NewTerrain.

Create a terrain in World, or replace the source of its terrain, as Manage, New's Create Terrain button does: one undoable "New terrain" transaction.

Place an editor-owned corridor, as the Corridor tool does.

Place an editor-owned plate, as the Plate tool's Enter does: one undoable transaction, kept by the authoring layer and baked by Bake.

Press a key in the terrain mode as the keyboard does in a level viewport: Enter commits a plate or corridor, Escape cancels (a commit waiting for its ground first), BackSpace takes a vertex back, Delete removes the selected feature.

Exact ground heights at Points_m (world X and Y, m), waiting until the ground there is resident.

Pick Brush in the active brush, paint or Stamp tool's palette, as a click on its button does, and set the mask's angle.

Turn the editor's background throttle ("Use Less CPU when in Background") on or off, in memory only.

Put the active brush tool's ring (or the Stamp tool's ghost) at Location_m (world X and Y, m) as a hover would, and hold it there while the mouse crosses the viewport.

Start a tool of the mode's palette, as its button does: Sculpt, Smooth, Flatten, Paint, GroundClass, Holes, Plate, Corridor, FeatureList or New.

Write a PNG of the largest editor window after Delay_s, drawing the level viewports first.

Undo the editor's last transaction (a stroke, a feature, New) and let the terrain settle.
