    USE:

    The model uses Danbooru/E621 tags similar to anime models. I would not recommend just generating a character with no follow-up prompts as the results won't look very good. A good negative prompt also helps greatly.

    Limitations:

    Some characters generate less consistently. This problem will be consistently worked on as new versions progress.

    I wonder if a SDXL model is in the works? Mind you, this model is fantastic for being 1.5. I was using SDXL models exclusively for other things but this seems to be the only really good Sonic characters SD model.

    I tried making one at some point but it wasnt very good. Honestly going to wait a while for the ecosystem to mature. Its too expensive to rent GPU's to experiment with.

    100_L128Nov 1, 2023· 1 reaction

    @metal079 Understandable. Main reason for SDXL for me would be the many artistic Lora’s out there.

    Nevertheless your model here is great, I’m having a lot of fun generating Sally art with it! 😅

    I tried the Mobians.ai website and this new V4 update seems noticably more stable than the previous ones, good job. Whatever it is you are doing seems to be working.

    I can't seem to replicate the results from Mobians.ai anywhere else. What settings does the site use?

    The site uses eular a at 20 steps. But it also has optimizations to speed up image generation that make it non-deterministic. So the images can't really be replicated sadly.

    fp16 version when?

    Every time I try to generate something via Stability Matrix, I just get a grey square as my final result instead.

    Civitai is testing a new generation backend, and unfortunately generates more black or gray squares than actual images...

    LeoTheLegend76Feb 29, 2024

    Tell me about it Bro, what are they testing man?

    OmegaArts13156Mar 1, 2024

    Yeah, having the same problem...

    3421505Mar 3, 2024

    Yup

    henseybrian9944Mar 4, 2024

    Same problem here.

    OmegaArts13156Mar 4, 2024

    It's weirder that it seems to be only model from one's I've been using to have this problem, rest work - MOST of a time.

    @OmegaArts13156 You can tell when the problem is on the website's part, and when it's the model's fault

    RikmachMar 8, 2024

    I've not been able to generate anything but black or gray squares at all today.

    OmegaArts13156Mar 8, 2024

    @Rikmach ...Yeaaaah it's been like that for few weeks now.

    Leon_WolfrenMar 26, 2024

    Yeahhhhhhh.... I don't get it either... I wonder if it's broken and they are trying to either fix or replace the model tensors....

    Leon_WolfrenMar 26, 2024

    @LeoTheLegend76  idk... At this rate the answer is meth

    hay! For some weird reason, most of the time when I use this model, it just gives black, gray, or horribly pixelated results. mind figuring out what the problem is?

    jcerritolu24570Mar 10, 2024

    I don't know but I hope it gets fixed

    BlackDiamondAIMar 12, 2024

    adding a VAE seems to fix it

    @blckroughdmnd560 which do you use?

    BlackDiamondAIMar 15, 2024

    @fallendragonwolf115 I stuck to ClearVAE but any of them should work

    Black and Grey images appear for constantly regardless of Lora or vae inserted ....this pains me in more than one way

    You're not the only one that had problem

    DidntiSaySoJul 16, 2024· 1 reaction

    If you're using A1111/Webui-Forge i set the "SD VAE" to"Automatic" and i got clear results instantly. No Black or Grey screens. Hopefully this helps. (Source: I struggled for hours to get this to work lol)

    As an artist myself, I like to use AI more as inspiration. While others say AI is toxic, I see it more as an advantage point. It's really good at helping me come up with inspiration for art and character designs. It's really good, honestly.

    ThinkerTankerApr 19, 2024· 1 reaction

    I feel like ai art has huge potential to be used as a ref that artist can use or like you said used for inspiration. Many artists are against it which is understandable but at the same time it can be used as a great tool help beginner artists and experienced artists with drawing things that could be difficult to find a ref for. I personally have had a hard time finding good refs but i feel that ai art has helped me a decent amount with that. Like I said i believe that ai art should be seen as another tool in an artists arsenal rather than the black plague lmao.

    I saw this in another comment, but I too (when using the model) have it generate within Black and white more often than not.. even after playing around with different prompts/negative prompts. Jump bumping back up to the top of your radar.

    "Error Message

    There was an error attempting to generate your image. Website is possibly down. Try out generating on CivitAi as an alternative. https://civitai.com/models/1493"

    Are there're intentions of reviving Mobians.ai?

    I see no probabilities of this model being elected to be used in CivitAI's generator.
