This is a tiny resource mod that allows to cast multiple dynamic shadows on both Software and Hardware renderer without need of shaders or any special stuff, pure DECORATE and ACS! You can use it for your own projects without asking for permission.
The thing is that right now is somewhat primitive and needs some revision. If you want to contribute for it's development, feel free to do it and i will update the post. The code is documented so you can understand how to make it work, but remember that you need some .wad/pk3 edition tool like Slade if you want to do proper testing.
NOTE: To test it on-the-go on default Doom 1/2 maps, just type on the console:
summon shadowbrain. And if you want to see your own shadow: summon shadowplayer
Here's a video explaining how it works:
