Weekend Progress

I mostly messed with some textures this weekend and rendered my first rough animation of the factory itself. I started adding in the emitter as well and I'm currently working with getting my objects to stay inside the basin. However, I'm considering slightly changing my factory. I can't seem to change the color of the clouds I made, no matter what I do and that is super problematic since I needed the clouds to be a dark purple/black/grey. I'm looking for alternatives to clouds that can give me the same effect or considering making my factory a star factory instead of a universe factory.
