If you are not tired from me... I want to discuss another shader practice - scene lightning.
At ideal it will look in editor as:
1. User drags spot light on scene from palette
2. Set it properties
3. All around is lighted.
I want to use that practice in my game and try to make some demos of what I mean. I will post light demos here - and may be new idea will appear - how to make automatic scene lights in framework. Such simple - that anyone could use it.
