Members

Name	Documentation	Type	Description	Optional
TextureSource	This value specifies a directory of images that are loaded from disk and is used as a texture that is applied to this sphere. The images are expected to be an equirectangular projection	String	Value of type ‘String’	No

Inherited members from Renderable

Name	Documentation	Type	Description	Optional
DimInAtmosphere	Enables/Disables if the object should be dimmed when the camera is in the sunny part of an atmosphere	Boolean	Value of type ‘Boolean’	Yes
Enabled	This setting determines whether this object will be visible or not	Boolean	Value of type ‘Boolean’	Yes
Opacity	This value determines the opacity of this renderable. A value of 0 means completely transparent	Double	In range: ( 0,1 )	Yes
RenderBinMode	This value specifies if the renderable should be rendered in the Background,Opaque, Pre/PostDeferredTransparency, or Overlay rendering step	String	In list { Background, Opaque, PreDeferredTransparent, PostDeferredTransparent, Overlay }	Yes
Tag	A single tag or a list of tags that this renderable will respond to when setting properties	Table, or String	Value of type ‘Table’, or Value of type ‘String’	Yes
Type	This tells the type of the renderable	String	Value of type ‘String’	Yes
