So, I had a bit of time and really wanted to play around with my main RealCartoon3D checkpoint. I still love the way my primary checkpoint that started it all runs prompts and updating it is getting to be a really picky process lol; but I really enjoyed the outputs and figured I would share it with you all as version 18. I hope you all enjoy V18 as it is more likely the last one for awhile.
