!!!!IMPORTANT!!!! for using this wad you have to open "Light Shadowmaps" function in GZDoom engine, its (if not changed in recent updates) off by default you can find "Light Shadowmaps" at Options > Display Options > Dynamic Light Options Also the first button that gets you to outside isn't working due to Light Shadowmaps'es nature don't worry you can get to outside from the back door.
This version based on CR4ZZY D Productions'es "How to make 3D lights in Doom Builder" projects, so all credits to him for the idea. Go check out the guy, he's cool, he has a youtube channel.
For running this mod smoothly you might need an really good computer, i have gtx 1070 and its still frame dropping jurassicly at the room before the last room.
Using smooth doom actualy helps with frame drops at the last rooms for some reason.
Also if you playing this mod with brutaldoom for the sake of your gpu do not point your flashlight under or over the 3d celing lamps.
