Draws the node as its children combined by operation: union, difference or intersection. The children stay in the tree, hidden and editable; color, texture and material dress the result.

In a scene, boolean3d is the node key that applies it. A script reaches each property below as a field on node.boolean3d: reading one asks the running component, and assigning one leaves the rest alone. The whole table is node.boolean3d.get() and node.boolean3d.set(table).

Properties

property	type	default	description
`cast_shadow`	bool	`true`	Whether the result casts a shadow from the lights that cast
`color`	color	`[0.8,0.8,0.8,1]`	Tint of the result, as channel floats or #rrggbb / #rrggbbaa
`depth_test`	bool	`true`	Let the scene hide it; off draws it over everything drawn before it and leaves the depth as it was
`dot_color`	color	`[0,0,0,0]`	The vertex dots' colour; an alpha of zero takes the node's own. Not drawn on a skinned mesh, which Balaur poses in its own vertex stage
`dot_size`	float	`0`	Size of a dot drawn on every vertex; zero draws none. Not drawn on a skinned mesh, which Balaur poses in its own vertex stage. Not on WebGL2 At least 0.
`dot_sizing`	enum	`world`	What `dot_size` counts: `world` is pixels at one world unit from the camera, thinning with distance, `screen` is pixels One of `world`, `screen`.
`draw_surface`	bool	`true`	Whether the surface draws; off leaves the wireframe and the dots alone
`light_layers`	int	`-1`	Light-layer bitmask; a `light3d` lights the result when their masks share a bit. -1 is every layer
`material`	asset · `material`	—	The material the result draws with; empty takes an inherited `material` component, else the built-in one
`operation`	enum	`union`	How the children are combined, in the order they are declared One of `union`, `difference`, `intersection`.
`receive_shadows`	bool	`true`	Whether shadows land on it; off lights it as if nothing stood between it and every light
`render_layers`	int	`-1`	Layer bitmask; a `camera3d` draws the result when their `render_layers` share a bit. -1 is every layer
`segmentation_id`	int	`0`	The id `render.snap_aov("segmentation")` colours this node by; nodes sharing one share a colour. Zero takes one of its own, from 1 up At least 0.
`texture`	asset · `texture`	—	Image file, project-relative, or a `texture` asset the result is drawn with, over the UVs the children carry through the cut; empty draws the colour alone
`wireframe_color`	color	`[0,0,0,0]`	The wireframe's colour; an alpha of zero takes the node's own. Not drawn on a skinned mesh, which Balaur poses in its own vertex stage
`wireframe_sizing`	enum	`world`	What `wireframe_width` counts: `world` is pixels at one world unit from the camera, thinning with distance, `screen` is pixels One of `world`, `screen`.
`wireframe_width`	float	`0`	Width of a line drawn along every triangle edge; zero draws none. Not drawn on a skinned mesh, which Balaur poses in its own vertex stage. Not on WebGL2 At least 0.

Asset types this component references: material, texture.

Script functions

Methods of node.boolean3d, the handle a node carrying this component exposes. Every handle also has get(), set(table), patch(table), has() and remove().

From render:

method	what it does
`built_mesh() -> any`	The triangles the node's boolean settled on, as `#{ positions, indices }` ready to be written out as a `mesh` asset; nil when the node draws no built geometry.
