Hey thank you so much! I wandered on your page and saw really cool concepts! I don't like people gatekeeping knowledge so here, I'll give you all you need for "basic" character generation. I use AI for concepts and then redraw everything piece by piece so I'm able to animate them.
Here's the workflow:
CKPT: catCitronAnime_v10 / VAE: Grapefruit
sampler: DPM++ 2M Karras / sampling steps: 30
res : 512x768
HiRes.Fix:
Upscaler : 4x-UltraSharp / Hires steps : 15 / Denoising strength : 0.35 / Upscale by: 1.5
[If you want to make characters older you'll have to redraw their faces manually btw. ]
I got better at Live2d! Next update will feature eye, mouth and hair animations! If you want to I can give you tips.
Hope this helps!
