Big Thanks to cnov rain for testing BulaR series with his awesome art ❤❤❤

Without him I would have a hard time improving next version

Usage recommendation

Is highly recommended to use Hiresfix or you will get bad results

Sampling Method + Hiresfix

Euler Ancestral + Latent (nearest-exact)
DPM++ SDE Karras + 4xUltraSharp
DPM++ 2M Karras + 4xUltraSharp

Steps : 25+

CFG scale : 7 - 10

Resolution : 512x768 (Portrait), 768x512 (Landscape)

Quality Prompt : masterpiece, best quality, incredibly absurdres, ultra detailed, ultra quality, 8K, sharp focus

Negative Prompt : (worst quality, low quality:1.4), interlocked fingers, bad anatomy, disfigured

Of course you don't have to use all the prompts, just take what you need

This also works well with anime tags, so you can combine them

Hiresfix

use latent (nearest-exact) with Euler Ancestral

hires step you can set as before or 15 - 30

if you use latent (nearest-exact), denoise strength can't be below 0.5 because the image will be broken (if you force it maybe 0.35 is the limit)

use 4x-UltraSharp

if you use 30 sampling steps, the hires step will be 15 or 20

use 4x_NMKD-Superscale-SP_178000_G

use hires step 20 - 25

if you copy image preview please first checking hiresfix setting and seed

ADetailer

use face_yolov8s.pt default setting

if you feel the face doesn't match the style try reduce Detection model confidence threshold around 0.2 - 0.3, also you can reduce Inpaint denoising strength if using LoRa or specific face of the character

you can use ADetailer Prompt for example you want 2 different color eyes input "heterochromia, red eyes, blue eyes" or pupil shape, something like that

ADetailer Negative Prompt functions like a regular negative prompt. you can leave it blank

Note : ADetailer is only used if the person is at a distance or in full body. but it's okay if you want to use it up close

Those are all the settings that I used. You don't have to follow this guide. it's all up to you~
