    Stormfly/Deadly Nadder (How To Train Your Dragon) [PonyXL/Illustrious] - Pony (V1)
    NSFW
    Preview 29528385

    Introduction

    Stormfly/Deadly Nadder from the series How to train your Dragon. A mix of SFW and NSFW pictures were used, especially screen caps from the movies and series. Most pictures were however trained on Stormfly so there will be a bias in generation probably.

    This model is now available on both Pony and Illustrious! Read below for prompts and notes.

    Using This LoRA and want to support me? Use the 'add post' in the gallery below - This gives me a lot of blue buzz to train more LoRAs!


    Illustrious (V1)

    It should be able to generate:

    • With weightage about 0.8 to 1 for best results.

    • Feral and Anthro (Use trigger words "feral" or "anthro")

    • SFW and NSFW

    Prompts

    Trigger Words: Deadly nadder

    Additional prompts: dragon, scales, tail, (wyvern, no claws, one horn on nose, wings, bipedal, feral:1.3)

    Prompts for Stormfly: Stormfly_httyd, female, blue scales, yellow sclera

    Optional Prompts: tail spikes, spikes on tail

    Notes

    • Model is trained on the base Illustrious model.

    • Generation quality should be about 80 - 85%+ accurate. This means you should generate mostly without much problem with proper prompting, but might still face that occasional error.

    • If you want to generate a proper wyvern form without hands/claws, make sure to include 'no hands, no claws' in negatives including the trigger words in brackets. This was the best way I found to generate consistently, but you still face errors from time to time (extra horns, wrong placement for horn, hair, etc)

    • See my images for prompt help if you need since this might be a tricky one.


    Pony (V1)

    It should be able to generate:

    • With weightage about 0.8 to 1 for best results.

    • Feral and Anthro (Use trigger words "feral" or "anthro")

    • SFW and NSFW

    Prompts

    Trigger Words: deadly nadder

    Additional prompts: dragon, scales, wings, horns, tail

    Prompts for Stormfly: Stormfly_httyd, female, blue scales, yellow sclera

    Optional Prompts: tail spikes, spikes on tail

    Notes

    • Model is trained on the base Pony Diffusion model.

    • Not much issues that I've faced except for tail spikes that could be inconsistent if you are using it. Use the prompts for increased success.

    • Stormfly's wing patterns may be difficult to generate. Faced this problem with my Seawing LORA too. Not sure if it's a training issue or my tagging issue. May do a V2 if i know how to 'fix' it.

    • The 'Wyvern' issue is still a problem that I faced with Adine. Will test a bit more with this later. (EDIT: Please see suggested resource for a solution, created a new LoRA that might improve this!)

    • For anthro models, use "hands" and "fingers" in prompts for more proper human anatomy (standard 4 finger 1 thumb) or "claws" if you want a slightly more dragon look (typically generates 4 fingers)

    • For feral models, I tend to include these in negatives: "abs, fingers, belly button, hands, pov, human".

    Want to support me without Tipping? Here's how:

    1. Liking my posts, collecting my images or collecting my models all generate buzz for me.

    2. Generate more pictures of my models. I get a base commission from anyone who generates using my model, even without the tip.

    3. Leave a like on my model. This helps me with the algorithm in reaching more people

    4. Leave a review. I take all feedback very seriously, good or bad.

    5. Consider using the 'add post' under gallery... if you are posting pictures of just my This gives me A LOT of buzz, while you can also complete your daily post quest.

      Thank you very much!

    I see pony still struggling with wyvern wings, just like 1.5

    "The 'Wyvern' issue is still a problem that I faced with Adine"

    OK I see what you meant with this, it tries to generate it as a quadruped dragon, plus wings. When really it should be a biped plus wings. Still a very good lora, but yeah if you want to be a stickler for that aspect of "on-model" it doesn't quite make it.

    I actually created a LORA that might fix this problem: https://civitai.com/models/930651/better-wyvern-form-for-dragons-ponyxl (Not 100% foolproof still, but it helps with generating a proper wyvern for dragons.

    If it's alright, can you make a hungarian horntail?
