Hi there!
Dynamic lights is a good solution, but then there won't be any shadowmaps. And they also pass throw the walls.. And I can't effort myself to have/write shadowmapping shader to use dynamic shadows (it's too much for oldschool project). I'm aiming to have static shadows, but toggleable (with lights).
About using a shader to manipulate the static lightmap, is there anyone willing to help me out? Maybe even for money (would like to know, how much would it cost).
Best regards!
