I looked at this earlier (i might have replied to this topic i can't remember) but i only just realised how cool this is. Ash/Lads do you think its possible to do this?-
In my space game I could have normal and bump maps for all my objects, then have light sources in the game, that appear invisible until they hit an object (as you wouldn't really be able to see light in just black space i believe. Its only when it collides with an object). So we could make some really cool explosions and introduce a sort of flash light feature etc.
I don't even know if i can be bothered after these 5 years of making this game to fully complete everything. I can see it turning into a huge tech demo
But yeah, if that can be done please let me know.
