I've been trying to figure out the best way to handle lighting in the interiors of the buildings...and this little $39 dollar program was the solution to my problem.
It's very easy to use, and does it's job well...it supports lightmaps, radiosity, and all kinds of other cool stuff.
After a few hours of playing around I was able to generate lightmaps for all the interiors of the buildings I have in the game right now...here's some screens of how it's looking.
So I guess I'm gonna go with static lightmaps on the interiors of the buildings, and use my little shadow hack for the dynamic shadows on the outside of the buildings. For the shadowing of the people/cars/objects I'm just using a quad with a alpha blended shadow texture directly under the character...pretty standard.
I should have some really cool stuff later this week...
