Description de la source

There's few DMD2 upscale/refine workflows on this site but all are overcomplicated. Here's the essential simplest workflow presenting how powerful it is. I'm using this stuff at end of all image generation because its simply free 2-5sec, insane, not only upscale, but also subtle fix for every little thing.

DMD2 lora - https://huggingface.co/tianweiy/DMD2/blob/main/dmd2_sdxl_4step_lora_fp16.safetensors

At KSampler test with "start_at_step" in 60-68 range. Closer you get to 70 the less impact will it have on photo (less steps). Smaller number - more fixes (more steps) but also more intervention from the checkpoint that you potentially would not like. Input image should be in 768-1280 size. Bigger images can produce mutations like double knees.

To avoid that replace "upscale image by" node with forced resize where longest side is not bigger than 2048.

If you want be more aggressive with sharpness - resize image, pass it trough 1xReFocus upscaler and then do ksampler. https://openmodeldb.info/models/1x-ReFocus-V3

Commentaire généré par l’IA

Explication générée par l’IA à partir des détails de la source et de la configuration. Les suggestions sont clairement signalées.

Objectif

  • This DMD2 LoRA workflow takes an image through an upscale and refine pass, aiming to produce an enlarged image with subtle fixes.

Flux

  • ImageCASharpening+ is included from the ComfyUI_essentials node pack.

Entrées et sorties

  • The creator describes using it at the end of image generation; LoadImage and PreviewImage are listed among its nodes.

Dépendances

  • Named model files: 4x_foolhardy_Remacri.pth, bigLove_xl1.safetensors, and dmd2_sdxl_4step_lora_fp16.safetensors.

  • Listed node names: CheckpointLoaderSimple, CLIPTextEncode, ImageCASharpening+, ImageScaleBy, ImageUpscaleWithModel, and KSamplerAdvanced.

  • Also listed: LoadImage, LoraLoader, PreviewImage, UpscaleModelLoader, VAEDecode, and VAEEncode.

Configuration

  • Try KSampler start_at_step values from 60 to 68; the creator says values nearer 70 have less effect, while lower values bring more fixes and more checkpoint influence.

    Suggestion · non vérifié

  • To reduce the described risk of mutations, the creator suggests replacing “upscale image by” with a forced resize capped at 2048 on the longest side.

    Suggestion · non vérifié

  • For stronger sharpness, resize the image, pass it through the 1xReFocus upscaler, then run KSampler.

    Suggestion · non vérifié

Précautions

  • The creator recommends 768–1280 input images and warns that larger images can produce mutations such as double knees.

  • No license information is listed.
