fortheday / UE4 Animation Subsystem Architecture

Created January 30, 2019 07:12 — forked from ikrima/UE4 Animation Subsystem Architecture

Mapping Out The UE4 Animation Architecture Flow

	Animation Subsystem

	AnimInstance is the runtime animation class that maintains runtime data & plays shit
	- This is the parent class of the animation blueprint
	- Get Bone Transforms from a specific time t:
	○ Sequence->GetAnimationPose(Output.Pose, Output.Curve, FAnimExtractContext(CurrentTime, Sequence->bEnableRootMotion));


	UAnimationAsset is the classes that contain the actual data and also calculates bones & curves
	- UAnimSequence
