Go to: Related nodes. Attributes.

This node is used to blend between one clip to another. Rotations are handled differently than other types of channels. The rotateBlend attribute determines how rotations are handled. There are three different ways to blend rotations: Quaternion Short is the shortest path between the rotations in quaternion space. Quaternion Long takes a longer path between the channels being blended. Linear causes the rotations to be blended like the other channels. Both quaternion blend types use slerp. The other channel types are linearly interpolated with the weight attribute determining how the interpolation progreses. If the weight is 0.0, then the first clip is used. Likewise if the weight is 1.0, then the second clip is used.

The formula used by the linear interpolation is: o clip1 + (clip2 - clip1)*weight.
