FTransform
Namespace: UAssetAPI.UnrealTypes
Transform composed of Scale, Rotation (as a quaternion), and Translation. Transforms can be used to convert from one space to another, for example by transforming positions and directions from local space to world space.
Transformation of position vectors is applied in the order: Scale -> Rotate -> Translate. Transformation of direction vectors is applied in the order: Scale -> Rotate.
Order matters when composing transforms: C = A * B will yield a transform C that logically first applies A then B to any subsequent transformation. Note that this is the opposite order of quaternion (FQuat) multiplication.
Example: LocalToWorld = (DeltaRotation * LocalToWorld) will change rotation in local space by DeltaRotation. Example: LocalToWorld = (LocalToWorld * DeltaRotation) will change rotation in world space by DeltaRotation.
