public class GltfWriter : IGltfWritable

Constructors

GltfWriter(ExportSettings, IDeferAgent, ICodeLogger)

Provides glTF export independent of workflow (GameObjects/Entities)

Declaration

public GltfWriter(ExportSettings exportSettings = null, IDeferAgent deferAgent = null, ICodeLogger logger = null)

Parameters

Type	Name	Description
ExportSettings	exportSettings	Export settings
IDeferAgent	deferAgent	Defer agent (IDeferAgent); decides when/if to preempt export to preserve a stable frame rate.
ICodeLogger	logger	Custom logger for reporting messages. Defaults to the shared Instance (writes to Unity's Console) when null is passed. Pass Instance (or new NullLogger()) to suppress all output.

Methods

AddCamera(Camera, out int)

Creates a glTF camera based on a Unity camera
