One of the less inspiring things about jumping into Blender is that I've found environments and setpieces aren't quite as commonly shared as, say, character models. There are some, but not as many as you'd think. Thus one thing I find myself needing practice on is doing environments. For many of my sets, I've borrowed assets from other sources. The fact of the matter is that doing everything from scratch frankly doesn't make a whole lot of sense. All your time, especially when working solo, can be eaten up by environmental design.
This little strip club is a thing I've been working on. I've used an earlier version of it previously, but I'm working on making it complete enough to share so that others can have a nice, dirty environment to do their nasties in. You know, you gotta have fun with it.
