My development experience goes back about 30 years (Spaghetti programming in BASIC, if you can believe that).
In the end, it’s back to what I had it. I restored my computer using a saved image file from before I installed 4.5 (I do a full image every week - I run an IT business, after all). The funny thing was when I went BACK to my downloads page, I saw the 4.0 AND the 4.5 versions available for download with NEW SN’s. They hadn’t been there before I did the restore.
Long story short, I lost a day or two getting my library restored the way I wanted it and then re-doing the files. I’m not using 4.5 and don’t plan to. I didn’t take my own advice and not fix what ain’t broke.
I did discover that rendering large files (I require a 300 DPI resolution for book cover art and prefer not to cause too much pixelation by jamming in a 72 DPI image on it.) is VERY problematic. I can get it to render to about 8X10, but books being 9X12, plus spine, makes them too large. Beefing up the RAM didn’t help. So I ended up using a 200 DPI back-scene image (which worked, pixelation was minimized and it’s the background, after all) and the full 300 DPI for the main characters.
Instead of creating the whole thing in DAZ, I created each part separately - seven characters and a main background that was smaller than the whole thing, and then the back-scene at 200 DPI - and layered them in Gimp, then added the titling, spine and description. If I needed a slightly different pose, I just repositioned and re-rendered. It would have been faster doing most of it in DAZ, but given that I had about 300 objects between the characters and backgrounds, and still needed to add titling, authorship and the description on the back, it was just simpler to get the renders, cut out the characters, layer them and finish it that way.
I appreciate the help. Apparently someone at DAZ heard, got me my 4.0 Pro with a new SN and I’m back up and running, so all is right with my world.
