So, I learnt how to make defaults, and promptly forgot to actually make any after learning how. I decided to put my learning to use (finally) after having the ideas sit on a Windows sticky note FOREVER, and made something really small that seems useful, at least to me. Getting rid of that yellow patina (who am I to talk, I own a purple tub) was priority #1. So here's the two basegame showers, with some new, unremarkable, white textures.
Please remember to delete any other defaults of these two objects before downloading mine, or they won't work and I'll be sad! :(
