Members

static BaseUrl : string

static CorsBehavior : string

Default behaviour for cors in the application.

It can be a string if the expected behavior is identical in the entire app.

Or a callback to be able to set it per url or on a group of them (in case of Video source for instance)

static UseFallbackTexture : boolean

static RegisteredExternalClasses : { [key: string]: Object }

Use this object to register external classes like custom textures or material

to allow the laoders to instantiate them

static fallbackTexture : string
