More photorealistic, improved lighting, less saturation, darker
BigLove is a merge of Pony, bigASP and other SDLX models. The Pony releases of Big Love are a hybrid. They produces different images than both Pony & SDXL-based models. Pony tags are understood, but interpreted a bit differently. Some images lean more in the one or other direction depending on the prompt. It works with Pony loras as well as normal SDXL ones. It can turn anime/cartoon into photorealistic images in img2img.
Big Love XL is a combination of 5 different training branches of SDXL: original SDXL, bigASP, RealVis, Anteros and Pony. With a bit of Pony in it, some Pony loras (poses, characters) work too. It outputs a more photorealistic & creative look than the Pony versions and can also do paintings & cartoon.
Use Big Love here to create 60 free images per day with these settings. For discussing photorealistic image generation join me on Discord.
Pony/XL1 versions were optimized for the Lightning lora, XL2/XL3 for the DMD2 lora. Both speed up rendering by a factor of 3-6x and let Big Love produce more photorealistic results.
txt2img Settings:
Civitai: DPM2 a, 30-50 steps, cfg 4-5, 832x1216
Forge/ComfyUI: DPM++ SDE, Normal/SGM Unifom (Pony), Karras (XL), 20-30 steps, cfg 3-10, clip skip 2, 832x1216 or 1024x1536. For faster generation 2M SDE/3M SDE works too, but lower quality with the Pony version.
Higher Quality & Faster Rendering:
Good Quality: For more contrast add the SDXL Lightning 8-step lora with DPM++ SDE, SGM Uniform, 8 steps, cfg 1.5-3 (Pony), 1-2.5 (XL), lora strength 1.0, clip skip 2, 832x1216 or 1024x1536
Best Quality: For a more natural look use the DMD2 lora with LCM Exponential, 8 steps, cfg 1-1.5, lora strength 1.0, clip skip 2, 832x1216 or 1024x1536
Upscaling:
1. txt2img with Lightning 8-step lora: Hires fix, 4x_NMKD-Superscale-SP_178000_G upscaler, 3 hires steps, 0.4 denoise, 1.5x, hires cfg 2, clip skip 2
Higher Quality & Faster Rendering:
Good Quality: img2img with Lightning 8-step lora: same prompt, DPM++ SDE, SGM Uniform, 1.5x (XL), 2x (Pony), 3 steps (ComfyUI), 6-8 steps (Pony), 8-12 steps (XL), cfg 2, lora strength 1.0, 0.3-0.5 denoise, clip skip 2
Best Quality: img2img with DMD2 lora: same prompt, LCM Exponential, 1.5x, 8-12 steps (XL1/XL2) 4-8 steps (XL2.5), cfg 1, lora strength 1.0, 0.3-0.5 denoise, clip skip 2
Please note: Unlike txt2img with Hires fix, img2img offers a seed, so you get multiple image versions to choose from. img2img upscaling also produces better quality in A1111/Forge.
ComfyUI Workflow:
Download the following image and drop it into Comfy:
Lightning Workflow
DMD2 Workflow (recommended)
DMD2 UltraRes Workflow
With the Lightning lora it is better to use Forge. ComfyUI is not able to do as many upscaling steps with Lightning as Forge without adding grain. But if you use the DMD2 lora, ComfyUI does just fine. The UltraRes workflow also requires the UltraRes lora for hires output.
Strengths:
XL: Great fine details, very natural looking photo-like images, lovely faces, creative poses, can also do paintings and cartoon
Pony: Probably the most photorealistic Pony model, very good anatomy knowledge, huge face variety for a Pony model, very short prompts are quite effective & photorealistic
Weaknesses:
XL: Some prompts produce softer skin, multi-person images can have strange anatomy
Pony: Needs rather precise prompts & takes prompt rather literally, still a bit of the Pony look depending on used prompt, it can switch between fully photorealistic and semi-realistic
XL Prompting Advice:
SDXL prompts & prompts from Acorn Is Boning & Lustify work with it. Pony prompts too, but they create a more photorealistic look. Natural language prompts tend to create artistic glamour images with less skin detail while normal tags do more photo-style images. Big Love XL gives individual words more attention, so you don't need to rework prompts like Big Love Pony requires sometimes.
XL1/XL2 has a tendancy towards cuteness and bright skin. If you get too much of it, remove words like cute, sweet, pale/fair skin & flash from the prompt. It also creates realistical analog photos with reduced image quality. Sometimes better to remove terms like analog or grain to increase quality. Decrease cfg to get a more natural look.
XL2.5 can sometimes get too sharp. Reduce cfg or use less steps in img2img to make images softer.
Pony Prompting Advice:
Pony prompts & prompts from bigASP & Lustify work with it. Score tags and fill words like masterpiece or perfect skin have as good as no effect usually. A negative prompt is often unnecessary unless you want to make something vanish or avoid underage, but it can also change the style of the image.
Pure booru tags and some other samplers may produce Pony style. Photographic terms or a simple prompts ensure a photo look. Sometimes it refuses to produce medium shots, portraits or close-ups unless you weigh the term heavily or remove feet, shoes, high heels, boots etc. from the prompt. wavy hair sometimes does not look so great.
If it refuses to do porn, try simplifying the prompt. If you want to do a portrait, don't describe surroundings too much. If you want to do porn, describe the action mainly and don't focus on the people or surroundings in the prompt. The largest part of the prompt should be about the main subject of the image.
If a prompt does not produce the intended image, you often only need to modify it a bit to make it work perfectly.
Using Character Loras:
Big Love Pony supports Pony characters, but they look like real humans. There were some complaints about them not working, but the problem was not the model itself so far. So here are some tips:
* Try Pony as well as SDXL character loras
* Use a lora weight up to 1.5 if it does not reduce quality
* If it is a well known character, add the name in the prompt and also give it a higher weight if necessary.
* Check your negative prompt for problems. Delete it if necessary and rewrite it from scratch.
* Render a lot of images to be able to pick those with the best resemblance.
Higher Ouput Quality:
You can highly improve the images generated with this model by using img2img, upscaling, detailing etc. The Lightning lora enhances the look and sharpness despite only 8 steps. Alternatively, the DMD2 lora produces a sharp, but more natural look with less contrast. Also check out the Subtle Style loras, which nicely enhance images.
