--- Legacy description

• Sequence Blender component is used for easy blending between "mood states" of the world during the game. Setting of a day-night cycle or weather state are examples of such a "mood state".
• Sequencer is used as a WYSIWYG editor for these states. Every world state is represented as a single keyframe.
• Problem to solve: what if we need to jump between non-consecutive keyframes? We can't simply play the sequence. Player would see transitions through many states.
• Solution? Let's use custom code for reading a new state from Sequencer and nicely blend world objects to this state!

Most of the code is universal and it's easy to customize component for a specific game.

• Blending supports object properties: float, color/vector, transform.
• Component also blends Material Parameter Collections.
