No need to download/activate the Lora separately.DMD (Distribution Matched Distillation) allows you to generate fairly good quality images in as little as 4 steps with the LCM sampler. It cannot produce images equivalent in overall quality to a non-DMD2 checkpoint, so please keep this in mind. On the other hand, with 6-10 steps, this thing is fast as hell and outputs more than reasonable generations—which is great for anyone without a high-end graphics card.No PAG needed for this one. Just ~8 steps, LCM w/Exponential at CFG ~1-2.0. A convenient workflow is provided that will get you off the ground running with text-to-image, an additional DMD2 fast upscale with a Tile ControlNet (to keep things intact while adding detail), and a bonus FaceDetailer node that also takes advantage of the speed of DMD2/lcm. A major weakness of DMD2 is that the low-cfg requirement eliminates attention to the negative at cfg=1.0. My workflow adjusts the noise tonemap and rescales cfg so that you can boost cfg a bit and still have that negative prompt perform somewhat functionally.

If you decide to generate at this resolution, the upscale and facedetailer portion of the provided workflow will be overkill.</li><li>Sharp</li></ul> DMD2 Bad:<ul><li>LCM isn’t great. Background details are a bit blurrier/painterly</li><li>Low steps means less attention to prompt and less fine detail overall</li><li>Slightly less creativity in terms of pose and composition</li></ul> Some options:<ol><li>Download the XXX-Ray DMD2 checkpoint, download the workflow (<a target="_blank" rel="ugc" href="https://civarchive.com/articles/13329/xxx-ray-dmd2-basic-workflow">https://civarchive.com/articles/13329/xxx-ray-dmd2-basic-workflow</a>), get the custom nodes + CN models required for that flow (links in the workflow), generate.

It was tailored to produce slightly darker and grungier images, which is my own stylistic preference. I'm primarily releasing this for friends who've been asking for it, but also anyone else who is looking for a "moodier" realistic model that has good skin texture, lighting, and prompt adherence, but doesn't want that "Pony" look. No Pony derivatives were merged into this mix (v1.0). If you like the types of images that I generate, you'll probably like this model too. Good for both sfw and nsfw.Many of your favorite realistic models are included in this merge to some degree, so expect similar results. It has been tested against other popular merges with X/Y plots and is able to generate unique output. Great for selfies, polaroid-style images, and analog shots in general. Good for upscaling too, though perhaps not as good as the incredible <a target="_blank" rel="ugc" href="https://civarchive.com/models/573152?modelVersionId=1094291">Lustify </a>at the latter. It gets skin color/tone right most of the time. Its weaknesses are eyes (which is an easy fix with a detailer) and the occasional floating wang. Also not great for anything too fantastical. Overall its pretty good, and once in a while knocks it out of the park. Have fun with it. And remember, you get what you pay for.The example images include a basic Comfyui workflow that I whipped up to help you get off the ground. XXX-Ray has been tested in ReForge as well and works as intended with the suggested settings below.Some advice for its use (V1/V1.1):<ul><li>Use PAG (Perturbed Attention Guidance) at ~1.5-2.0.</li><li>Asp tokens were kept intact as best as possible in the merging and work well: (<a target="_blank" rel="ugc" href="https://gist.github.com/fpgaminer/0243de0d232a90dcae5e2f47d844f9bb">https://gist.github.com/fpgaminer/0243de0d232a90dcae5e2f47d844f9bb</a>).</li><li>The Detail Daemon sampler (~0.04), like PAG, will boost output quality.</li><li>Using score tags (e.g. score_7_up) will affect your generations slightly, but they are not strictly necessary.</li><li>Use the included comfyui workflow if you're having issues: <a target="_blank" rel="ugc" href="https://civarchive.com/articles/9981">https://civarchive.com/articles/9981</a></li><li>Upscaling is your friend. This is also included in the provided workflow.</li></ul>Settings that have worked well for me with this merge (V1/V1.1):<ul><li>DPM++2M sde Karras at 23+ steps, DPM++ SDE Karras at 18+ steps, or DPM++2M sde AYS at 14+ steps.</li><li>CFG ~4.0-4.5.</li><li>PAG (strongly recommended) at 1.5-2.0.</li><li>If you'd like to use DMD2, use the 4-step LoRA, LCM w/Exponential at 8-steps, CFG = 1.0-1.5.</li></ul>Note: Credit to @nutbutter, @erotes_anteros, @coyotte and @ndimensional for their masterfully trained checkpoints.

XXX-Ray

Keeps the same texture, lighting and moodiness from v1.0 but is now slightly better at generating consistent and coherent anatomy. Also has better eyes, more fine detail (e.g. skin), and better contrast and shadows. Does not improve all aspects of v1.0, so you'll have to experiment to see which you like best.
