This is cool software. However I'm concerning over the practicality of this. Don't get me wrong I would love to use this in my games. I think the effect of dynamic lighting like this is gorgeous and adds depths. BUT.
1. This is PC only tool. The result is 4 images per frame of any given sprite. 1 Diffuse and 3 Maps base on the light system. I have a demo game that has the PC where one animation has 60frames. That's 240 frames with SpriteLamp. memory and storage wise this is shot.
2. Developer needs to create the base light maps to be processed. The guide shows that while it exports 3 maps it needs 2 to 5 light inputs. Again that's going to be for just one animation 60 frams where I need to create these light inputs. Can't imagine what this would be like over the entire characters animation.
3. This seems impracticale due too number 2. HOWEVER this would work SUPER well for static parts of the level. Wich means that use of spritelamp only works best in games where light moves. Which is often dungeon games, dark exploration games where the ligth source is carried by the player.. though shooting blasters would look super cool too :D. But again only the terrain gets' the beenfit.
4. The Only practical way to make this work for moving characters is to use Spriter/Flash like tween based animation. That's why dynamic lighting works for 3D models. 1 Light map and it's MAPPED over the 3D model. Spriter based animation would still require more. but at least it's not based on the sprite's angle an not per frame.
BUT OH WOW. I would love this in my games.... super coool. WANT WANT WANt.
