    Detail(noise) level between v62 and v61, upgrade character/artist accuracy.

    v6.4 [2D,3D,Real,896~1536]

    Upgrade light quality and average detail.

    Note about NoobXL to create stable furry (v6x):

    use "furry" tag in propmt can let AI create furry not human.

    use "no human" tag in propmt can avoid NoobXL model add human and reduce anthro affect (more original style).

    use "anime style" in negative propmt can reduce classic booru style and more realistic.

    Some SD prompt trick:

    Combine two character:

    characterA \(characterB\)

    Avoid tag bleeding:

    (chain:0)-link fence

    (cowboy:0) shot

    high (collar:0)

    Multi-tag combine, enhance and reduce token use:

    from side + side view = from side view

    Maybe this is an issue specific to Invoke, but when I try to run v41 and v42 with the config in the same folder as the model I just get runtime errors. v36 works fine still at least.

    Most common settings for SD-A1111 or SD-Forge.

    Only SD2.x and some SD1.x furry models use v-prediction.

    But SD2.x vpred setting can't use in SD1.x, Sometimes problem from here.

    There's a InvokeAI vpred branch (didn't test) .

    You can try SD-Forge, same SD-A1111 interface and more faster less vram use.

    (include python+git and bunch of builtin extensions)

    WD-KL-F8-Anime2 already baked in v4.x, but I recommend Furception

    Argon42Mar 23, 2024

    @chilon249 If it's already baked in, does it get overridden when I select another VAE in the settings or are they both used at the same time somehow?

    VAE setting "None" or "Automatic" = use baked VAE

    select another VAE will override it.

    @chilon249 Ok, thanks.

    denis0kMar 24, 2024· 1 reaction

    Small correction: if you rename downloaded VAE as a model name and place it in folder with model, then, if you choose "Automatic" setting, will be used external VAE and not baked.

    Any chance for a pony XL finetuning using your dataset?

    MobbunMar 24, 2024· 1 reaction

    YiffyMix is a merge, not a finetune. It relies on other models being trained in order to merge. There are few XL models and Pony is mostly incompatible with them, so I wouldn't expect a merge anytime soon.

    # V-prediction model has following feature #

    Low-Rescale CFG : low frequency noise, cluster detail, high contrast

    Sometimes less detail but smooth surface color and less mutation.

    High-Rescale CFG : high frequency noise, flat detail, low contrast

    more detail can be shown, but not like EPS (non-vpred).

    You can see the visible halftone dot in "starry night sky" or "grassland".

    try "halftone background" to test it.

    Are you using SD-WebUI a1111?

    If you can't load new model, try remove "cache.json" and restart SD-WebUI.

    SD-WebUI will rebuild model list.

    This model is kickass, I love how I can mix different artist styles to get an eye-candy result. I use v3.6 because newer versions tend to have a weird yellow-ish tint which I don't like. The only significant downside is total incompatibility with AnimateDiff - spent a whole day trying to get it to work to no avail.

    Try removing "detailed pussy" from your prompt and moving your negative embeddings into the beginning of your negative prompt. For example start your neg. prompt with "boring_e621_fluffyrock_v4, EasyNegativeV2 verybadimagenegative_v1.3 ng_deepnegative_v1_75t" and then goes the rest. Also try adding "mutilated genitals" to your neg.prompt.

    RU_BlackPantherApr 15, 2024

    @oaf40 This didn’t help, what other options might there be? By the way, can the emebedding be mixed? Do they not interfere with each other? Can you reproduce my problem or does your vagina look normal in this case?

    Now it looks like this, thanks for the tips!

    Can you suggest a word that would allow us to bring the “camera” closer to the pelvis? So that it would look like she are looking down and the camera is sort of between her legs. I am not a native English speaker

    oaf40Apr 15, 2024· 1 reaction

    @VladossX I'm afraid I won't be able to reproduce your picture because I will face multiple issues, I am running SD on an old AMD videocard and I've explicitly set the "Random number generator source" setting to "CPU" while most people have it set to "GPU" which is not cross-platform and won't yield the same image as yours. And generating a 1024x1024 picture will take at least half an hour. Sorry for not being able to help this way. One of the options you can try is to download some pussy-specific LoRA (search for "pussy" on civitai) and enable it in your prompt.

    > Can you suggest a word that would allow us to bring the “camera” closer to the pelvis?

    try the "foreshortening" token with increased weight and specify "pussy in focus" as well.

    >One of the options you can try is to download some pussy-specific LoRA (search for "pussy" on civitai) and enable it in your prompt.

    I thought about it, but it's mostly human lora or anime, is this suitable for furries?

    oaf40Apr 15, 2024· 1 reaction

    @VladossX yes usually it should work, try playing around with the weight of the LoRA. If it looks too "human", decrease the weight. Also I've just remembered,

    > Can you suggest a word that would allow us to bring the “camera” closer to the pelvis? So that it would look like she are looking down and the camera is sort of between her legs

    Besides "foreshortening" and "pussy in focus", try adding "low angle" or "worm's-eye view". To make your character look down at the "camera" use "looking down, looking at viewer". I recommend you to read this page on angles and perspectives https://e621.net/wiki_pages/10866 , all tags from this page should work in yiffymix model.

    RU_BlackPantherApr 15, 2024

    @oaf40 
    Sorry to bother you, but what word can remove hands? It produces a picture like this, https://civitai.com/images/9953995 I don't need hands reaching for the "camera"

    Thanks in advance for your help. I won't bother you anymore!

    oaf40Apr 15, 2024

    @VladossX You can make her use her hands in some other way instead of reaching the viewer. You can check out my old post https://civitai.com/posts/1955266 and see the tokens I've used for that: "(breasts, fondling, holding breasts)". You might also want to try adding "(reaching towards viewer)" to the neg.prompt.

    > I won't bother you anymore!

    There's no problem with that, I will try to help if I can ;) Cheers!

    Excellent model, but I have absolutely no luck with getting v_42 rid of the yellow tint. No matter what I try.

    I do have:

    - SD - Forge

    - loaded ".yaml" config (at least console says "left over keys: dict_keys(['v_pred'])" when loading model)

    I have tried:
    - Rescale CFG plugin: (0.0-1 with not much success, Auto Color Fix did improve things a tiny bit, but it is inconsistent, and when doing batch size, it applies barely in the first image, much stronger on the second etc..)

    - LatentModifier Integrated (Rescale Cfg Phi) or whatever is there with no desired effect, the higher number of Phi introduces unwanted fractures and artefacts (colourwise it is ok thought)

    - whatever embedding, VAE, or low-contrast prompt there is.

    Anybody has found a solution? Or have a tip? Thanks.

    @chilon249 Am I correct to understand that in v3.6 only the artists listed in the "Species/Artists grid list" are recognized by the model? For example I'd like to use rz54's and skorpdk's style but they aren't in the list, does the model know their styles nevertheless? Tried making few test prompts but ngl it's quite hard to tell. Apologies for highjacking the comments section, I just thought my question isn't worth a dedicated thread.

    Merge model like black box, it contains lot of concepts.

    I don't know what it can do, only test each tags step by step.

    This specie/artist list from old FluffyRock csv tags.

    I think is enough to cover most e621 concepts.
