save_spatial_snapshot()

MAYAFLUX_API bool MayaFlux::IO::save_spatial_snapshot	(	const std::string &	path_pattern,
		const std::vector< SpatialCaptureSource > &	sources
	)

Open a fresh SpatialCache, write every source once, then close it.

Splices a millisecond timestamp into path_pattern the same way save_mesh_snapshot does, so repeated calls never collide. A single time sample rather than a recording: useful for an ad hoc "what does this look like right now" export.

Returns

False if the cache fails to open or any source's capture_frame() call fails.
