Animation blending in Castle Game Engine
Animation blending means that the transition between animations is smooth. Without animation blending, the old animation instantly stops and the new animation plays. With animation blending, there is a short time during which the old animation "fades out" (it's applied with decreasing strength) and the new animation "fades in" (analogously, it's applied with increasing strength).
The movie shows this technique in action in new Castle Game Engine ( https://castle-engine.io/ ). Notice how animation changes are sharp when TransitionDuration is zero, but they are smooth when TransitionDuration is larger. This is especially visible when switching between "Idle" and "Attack" animations on the 3D knight model.
