The Development Project is a HL2 modification made out of manipulated Dev textures as a project for those that enjoy the simplicity of the original measuring textures created by valve scattered throughout the map but also enjoy all the effects, adventures and creativity of regular mods.
A template I made today in hammer until its made into a 3D Model that one day will hopefully require an item such as pliers to use on in order to open a door or other things.
The 3 wires indicate power, lock and unlock to a door, at some point I wish to make it so when pliers are used on the wrong wire, it will open different accesses to get past a certain area.
Black will be for power of which if cut will throw the player half way across the room and disable the door all together.
Red will for the locking mechanism of which will unlock the door when cut. Blue is for the operations and will stop the door completely much like the black.
These ideas are of course in the works as it was a day make and a day post.
