Lately I've been using AI to generate character portraits since I'm terrible at art. This actually came in really handy for PaizoCon, since everything was on VTTs. Here are a couple of ones that I've gotten that were good enough to keep. They're definitely not perfect, but you can upload them back into Nightcafe and have the AI keep working on them later
Hokgnath Bladegnawer (Battle Oracle/Mindsmith)
Matu'uk Bladegnawer (Giant Barbarian)
Jerhyn Skorn (Throwing Magus/Rogue)
I stalled Stable Diffusion some time back and have since been using it to make a lot of character art as well.
Was to be my gunslinger character in a just cancelled game:
Was to be my fighter character in another game (Blood Lords) from the same group that just got cancelled (our GM is taking time away from tRPGs):
And my druid from a game that is just hitting it'd fourth session:
Installing Stable Diffusion gives you the ability to do large sized work, and to refine the results a lot more. That said, I work these back and forth between Stable Diffusion and Gimp (open source equivalent to Photoshop).
Here's the gunslinger, with some more refining I did recently:
I'm definitely going to have to check out Stable Diffusion; the stuff you have coming out of it looks great. I'm terrible at GIMP and not a visual artist at all, which is why I'm checking out AI to generate my stuff. How much post-processing work did you have to do in GIMP to get this quality?
I actually use Gimp not for post processing but to make guides.
I can make something very ugly in Gimp, and then run it through stable diffusion a sozen times and it will clean up.
That final image you see there, started as this.
I used a tool in stable diffusion called 'inpaint' to delete the second figure. which gave me a very rough looking background:
I took that into gimp and used smudge and clone tools to make that blur look more like sky. Than I ran it through Stable Diffusion's "img2img" tool that makes an image based on an image and your prompts.
I had to take this back and forth between stable diffusion and Gimp a few times to add in stars and fix the sky there:
(I had several of these where I'd just clone something to a spot, then have stable diffusion smooth it in.)
Finally I had one image with a great sky on the right, but the figure on the left was all wrong.
So I took the original '2 women' pic and my good sky image into gimp, and used a 'layer mask' at the halfway point to put the sky of my good image into the pic of the woman on the left.
So I took this image and ran it in Stable Diffusion's "img2im" again a couple of times and it made the blend natural.
This character was meant to be the cousin of my witch PC - was going to replace the witch with a gunslinger. The game just got cancelled yesterday. But the funny thing is the woman on the right remains in my folder of work images and could be used for the witch if I round out her ears. The gunslinger was a half-elf, the witch was human.
Sadly with that game cancelled both go into my pool of future characters now.
Anyway... the whole process I went through is why I get annoyed when people say AI art is all stolen and not original.
Just like photography you may start with something that came from an existing source - but it is perfectly possible to make it your original piece of art. And just like photography, a lot of people will thing you just clicked a button and got a result and don't deserve any credit...
The only difference is photography's been around for a while now so most people have gotten over themselves on the claims that it's just a snapshot of something that already existed. AI Art will eventually get the respect it deserves, once more people are doing original things with it. There are already people who go way beyond me to levels that would rival hand drawn works of art in their human craftsmanship.
Any advice for prompts or settings? I got stable diffusion installed but have been having issues getting good images out of it
