    Illustrious is great, except it is very "clean" and "bright"- grunge, dirt, darkness and atmospheric horror details are not its strong suit. This LoRA is designed to turn your bright, plastic-smooth and pretty images into gritty, grungy, horror-esque visions of urban decay and haunted nature. This style LoRA enhances edgy grunge characters, zombie apocalypse cities, eerie Halloween wetlands, Eldritch cursed shores, grimy apartment interiors, and more!

    Please read below for important usage details:

    Trigger Word: Please start you prompt with either the indoors, outdoors, city or grunge tag, this will activate the LoRA and help guide the image depending on which kind of scene you want. Add the tags night, grunge, dirty, damaged and/or gritty texture as desired to ensure consistent results.

    LoRA Strength- use 1 (full). You can go lower, but do not go over. Full strength keeps the style looking its best, but lower it a little if a certain concept isn't working. I had to use 0.8 strength to get raining weather to work (I'll remember that for a future update).

    Sampler: DPM++ 2M SDE is strongly recommended, or DPM++ 2M (cheaper onsite), but avoid Euler A! I normally prefer Euler A, but on this it "smooths" details too much and tends to look bad.

    All showcase images were made using the *Plant Milk Model Suite- Walnut" checkpoint. I linked it here under "suggested resources". I really recommend it, it's my favorite, and works best with this, but feel free to experiment.

    Because Hires-Fix will try to "clean" the roughness out of this I recommend skipping the Hires Fix step entirely. Even just 0.1 denoising strength removes some noticeable grit details. You can improve image quality by generating at a higher (SDXL supported) base resolution, adding more sampling steps, or using adetailer/face-fix options, but a full image-to-image Highres fix will scrub some of the "dirty" details away. Please look closely at the comparison below for an example:

    Finally, I want to thank my friends, too many to name, for all of their help testing and getting this model ready- I love you all! Feel free to peruse the showcase images and gallery for ideas and example, and if you find the model helpful, please consider leaving a review with an image post- it really helps me out 💕

    My Review!

    This is a great LoRA! It really does turn my bright and clean images into dirty more darker images! I really had fun generating 20 images with these LoRA and pushing it to its limits. It makes warfare images I’ve created into actual warfare with dirt and grime on my characters. It seems to handle cityscapes very well and looks amazing! This LoRA also handles many different types of anthros and outfits no matter how complex they are. The only issue I can come up with is that it is rather difficult to generate guns. Other than that! A great LoRA to try and spice up your details!

    Peak utility, I love this. And Walnut is a superlative model. You have good tastes.

    Totally agree! Before this LoRA came out, I was literally trying to figure out how to make the images look dirty almost every day XD

    Yes! Thank you so much for saying so! At first I was just trying to improve grunge, but as I kept going, I thought of so many things I wanted to see done better- rusted cargo containers, rotting wooden walkways in the swamp, dark paths that never see the sun winding beneath the shadows of trees and more... No LoRA can handle every possible scenario, but this surprised me with what it can add even to things I didn't teach it, and I'm so, so grateful and happy to hear other people are finding it useful, too!! 💀💗

    Okay this LoRA is unreal. The transformation it brings — the moon, the fog, the embers, the whole shift in lighting and atmosphere — it feels like it adds a completely different world to whatever it touches. Genuinely stunning work.

    (also kind of feels like you packed the "RTX On" toggle into a LoRA file 😭 the difference it makes is wild)

    Thank you for sharing this, you're so talented. 💛 I know I didn't quite respect what it was made for (dark environments), but I can't help praising its versatility. I'll definitely play more with this.

    Thank you so much, and your images are amazing!! I love seeing the variety this can do, and I pinned your images to the showcase to keep forever!! Although this had a focus on cities and nature darkness, its effect on lighting in general and realism boost really came out way better than I'd even hoped, and seeing it used in all sorts of images makes my day. Thank you again for trying it and that incredibly kind comment ⚞^◕⩊◕^⚟

    With Freija's LORA's they all have a deceptive multi-use. Through experimentation, I have devised multiple ways to sow EEEEEEVIL.

    So you're not getting one function out this, but multiple. Excellent work.
