Inherits Rotation

Members

Name	Documentation	Type	Description	Optional
Keyframes	A table of keyframes, with keys formatted as YYYY-MM-DDTHH:MM:SS and values that are valid Rotation objects	Table	Table parameters	No
ShouldInterpolate	If this value is set to ‘true’, an interpolation is applied between the given keyframes. If this value is set to ‘false’, the interpolation is not applied	Boolean	Value of type ‘Boolean’	Yes

Inherited members from Rotation

Name	Documentation	Type	Description	Optional
Type	The type of the rotation that is described in this element. The available types of rotations depend on the configuration of the application and can be written to disk on application startup into the FactoryDocumentation	String	Must name a valid Rotation type	No

Table parameters for Keyframes

A table of keyframes, with keys formatted as YYYY-MM-DDTHH:MM:SS and values that are valid Rotation objects
