Well, this was inevitable.
The dataset could have been better (and I rushed through the tagging process a little too much), so it has some limitations and faults, but I'm still extraordinarily happy with it. Decent chance I'll retrain it in the future, but I'll need to recover an old HDD first.
Main trigger word is gbfSilva.
Each outfit has its own trigger word, but they all still require some additional prompting. I should note that Gentian Blue isn't super consistent, given that none of the fanart is consistent, and her yukata is just too complicated with too little artwork to work with, so your mileage will probably vary greatly with it. It gets the hair right at least, which is the most important part to me. There is also some very minor bleed between her outfits--some basic negative prompting will usually be enough for that.
Don't prompt for hair color; it already gets it perfectly with 100% consistency (statistic based on thousands of generations), including the blue gradient that's prominently in all of her official artwork. It does tend to add earrings by default--I recommend adding that to the negative prompts. You shouldn't need to prompt for her ahoge, but it doesn't really hurt either.
For her original outfit (water):
SilvaWater, very long hair, side braids, crop top, cleavage, midriff, long coat, skirt, thigh boots
Recommended to put collared shirt, frills, lace in the negative prompts.
For her light version:
SilvaLight, very long hair, ponytail, twin braids, crop top, cleavage, midriff, black jacket, black pants, belt
Recommended to put ribbed shirt, criss-cross straps, lace in the negative prompts. It can be inconsistent with her jacket's length, but negative prompting around that tends to make it stick to either extreme, so I wouldn't necessarily recommend it.
For her summer/earth version (swimsuit):
SilvaSummer, very long hair, side braids, blue bikini, midriff, straw hat, hat ribbon, frilled sarong, thigh strap
No additional negative prompts should be necessary. It has a difficult time with the belt, prompting for it is up to your discretion.
For her anniversary skin (Gentian Blue):
SilvaGentian, very long hair, twin braids, ponytail, choker, blue dress, cleavage, highleg, bracelet
No additional negative prompts should be necessary. However, I would recommend adding more detail to the prompts if the less consistent results from minimal prompting annoys you. The sample images could give you some ideas, maybe.
For her yukata/fire version (mileage may vary):
SilvaYukata, hair bun, twin braids, hair ornament, flower, blue yukata, floral pattern, gold trim, purple obi, ribbon, red sash
Recommended to put hair ribbon in the negative prompts. I tried extensively to get the more elaborate elements of her yukata to work (see sample images for that), but it's just too difficult, unfortunately. Sad that fanartists seem allergic to her most beautiful alternate outfit (in my opinion, of course.)
Sample images were generated using SeaArt with a variety of models (denoted in their filenames, if you're curious), with Hand Fixer at 0.6 strength, and the embeddings Pony PDXL Negative Embeddings, Negative Hands, and Negative Embeds for PonyXL.
Settings used for all images:
Sampler: DPM++ 3M SDE Exponential
Steps: 40
Scale: 7.0
Clip Skip: 2
No upscaling or inpainting was used, with the exception of the DucHaiten-Pony-Real sample image (eyes looked pretty bad originally).
I tested primarily with anime models, but it also works well with 2.5D models, and realistic models can also work with some additional effort.
My favorite models to use with it are MeichiDarkMix_Reload, YesMix XL, Faceless Void Mix, and Speciosa 2.5D.
I don't ask for donations or anything--I'm just doing this because I want to. A thumbs up is more than enough for me.
