Hello all!
I am making this post here for others to post under this thread and share some assets, scripts, and whatnot that they find helpful to speed up the development process. Some of mine (in chronological order) are the realism mod because they make it easy to add some very sought-after things like day and night, advanced lighting, and head movement. In addition, I also love using the F3X tool because it speeds up the process of tedious building.
Remember, everything here is not limited to plugins, and share away
