How the node's collider3d cuts its mesh into convex pieces, for a convex_decomposition or a fit to one.

In a scene, convex_decomposition3d is the node key that applies it. A script reaches each property below as a field on node.convex_decomposition3d: reading one asks the running component, and assigning one leaves the rest alone. The whole table is node.convex_decomposition3d.get() and node.convex_decomposition3d.set(table).

Properties

property	type	default	description
`approximate_hulls`	bool	`true`	Estimate each piece's hull while cutting rather than building it exactly
`hull_downsampling`	int	`4`	How coarsely a piece's hull is sampled while choosing a cut; 1 uses every point At least 1.
`max_concavity`	float	`0.01`	How deep a dent a piece may keep before it is cut again At least 0.
`max_convex_hulls`	int	`1024`	The most pieces a decomposition is asked to leave; parry 0.31 passes it on unread, so it limits nothing yet At least 1.
`method`	enum	`vhacd`	How a convex_decomposition is cut: into convex hulls, or into voxel parts One of `vhacd`, `voxels`.
`plane_downsampling`	int	`4`	How coarsely the cutting planes are searched first; 1 tries every one At least 1.
`resolution`	int	`64`	How fine the voxel grid a decomposition cuts is At least 1.
`revolution_bias`	float	`0.05`	How much a cut prefers an axis of revolution Range 0–1.
`symmetry_bias`	float	`0.05`	How much a cut prefers a plane of symmetry Range 0–1.
