Save your rocks and eggs! I'm so used to installing the upgrade and forging ahead using the new version like I did the old one...but with 13 I've had to actually read the new manual! The new rendering process forces me to use the Post features in Superfly in order to get a usable end result for instance. Let's face it. We've got a MAJOR jump in 13.! And one that comes with a BIG LEARNING CURVE! You can send it back if you want to but if you do you will stay stuck in the past. AI is kicking ass in visuals and if we are going to stay relevant we've got to dig in and use our good old HUMAN CREATIVITY! AI can only use the "past". We can leap ahead...or not. I thought I was having problems with Superfly because I kept getting weird results until I stumbled upon the post-effects process. Now, no more black exports of renders, no more half colors on objects I painted gold, and no more glittery skin tones on renders I didn't do post-fx on. And since I mostly do NFTs I'm getting awesome looks! Give it a try. You're welcome!
