splat

Since 0.6

Use it in a scene entity's components list as { "type": "splat", … }. The contract writes the fields flat and refuses unknown keys.

Fields

Field	Type	Required	Default	Allowed values	Description
`asset`	`string`	yes			The `splat` asset holding the capture: a 3DGS `.ply` (Scaniverse, offline training; SH degree 0 to 3) or a `.splat` file.
`radianceNits`	`number`	no			Luminance in cd/m² of a capture colour of 1: the capture's baked light in the scene's units. Default: what the engine makes an unlit colour of 1, so under the `none` tonemap at exposure 1 the capture shows its own colours. More than 0; anything else draws at the default with a load warning.
`visible`	`boolean`	no	`true`		Whether the capture is drawn. Default true.
`axes`	`SplatAxes`	no		`y-up`, `z-up`, `y-down`	Which way is up in the file: "y-up" (default, as stored), "z-up" (photogrammetry, CAD) or "y-down" (COLMAP-trained captures). Applied before the entity's transform.
