v4.x is vpred version, need ".yaml" config with model, see version info. Non vpred version recommend v34 & v36

Example Setting Txt2img Setting

Steps = 40~50

Sampler = DPM++ 2M Karras, DPM++ SDE Karras, DDIM, UniPC

CFG scale = 5~10

Negative embeddings = deformity_v6, bwu ※[SD-WebUI\embeddings]

Hires. fix

Hires steps = 15

Denoising strength = 0.45~0.5

Hires upscaler = 4x-UltraMix_Smooth ※[SD-WebUI\models\ESRGAN]

Img2img Resize

Scale to = 1.5~2.0

Denoising strength = 0.45~0.5

ControlNet0 = softedge_hed, control_v11p_sd15_softedge

ControlNet0 Weight = 0.4~0.5

ControlNet0 Pixel Perfect = true

ControlNet1 = Reference

ControlNet1 Weight = 0.2~0.3

ControlNet1 Pixel Perfect = true

SD Setting

Stop at CLIP layers = 1

Eta noise seed delta = 0

SD VAE = kl-f8-anime2 ※[SD-WebUI\models\VAE]

Txt2img Animated Diff ※no "BREAK", tokens < 75

Steps = 30~50

Sampler = DDIM

CFG = 10~20

ImageSize = 512~768 ※large image less motion

model = mm-Stabilized_mid, motionModel_v03-anime

Number of frames = 10~14

Negative Prompt v2

unusual anatomy, pixel (artwork), mutilated, malformed, watermark, amputee,

restricted palette, mosaic censorship, deformity, sketch, unfinished, monochrome

Version Info v1.0 [2D,res:512~768]

old model, unstable, low resolution

v2.x [2D,res:512~896]

e621 dataset + 30~40% SD5 dataset

v3.0 [2D,3D,res:512~1088]

large dataset then v2.x version, can do 2D, 3D

v3.1 [2D,3D,Realistic,res:512~1088]

more realistic, but loss some concept (e621 tag count lower 1000)

v3.2 [2D,3D,Realistic,res:512~1088]

unstable version, use SNR version FluffyRock, more noise detail

v3.3 [2D,3D,Realistic,res:512~1088]

stable version, more detail, more sensitive to prompts

v3.4 [2D,3D,Realistic,res:512~1088] ※include Fluffy Rock Quality Tags-LoRA

stable version, more detail, clear result, reduce some noise (like bush,pattern)

v3.5 [2D,3D,Realistic,res:512~1088]

unstable version, contrast & detailed enhance

v3.6 [2D,3D,Realistic,res:512~1088]

stable version, more sensitive to e621 tags

v4.0 [2D,3D,Realistic,res:512~1088,CFG Resacale=0~0.35,VAE Baked]

v-pred stable version, remix from EasyFluff

accuracy anatomy and style with fewer prompt,

little dim blue average color with smooth noise, weakly negative prompt issue

recommend refiner [0.3~0.5] with YiffyMix v3.4~v3.6 (requires SD-WebUI A1111 v1.6)

v4.1 [2D,3D,Realistic,res:512~1088,VAE Baked]

v-pred stable version, color and low contrast fix, reduced realistic noise.

some issue:

If batch size > 1, sometime get little fried image (only obtrusive in realistic image).

Just generate again with same prompts with parament, it will return normal.
