ComfyUI-MDSNodes

the following custom nodes was build to use with The Ultimate Model Tester Workflow civitai link . They may also be useful for your own workflows.

Nodes

• Load Image (With Path) Loads an image and outputs its decoded IMAGE, MASK, filename, full_path, and directory.

• Top Upscale Models Selector (Auto-DL) Selects top upscale models (e.g., 4x-UltraSharp, 4xRealWebPhoto) and auto-downloads missing files when queued.

• ControlNet Select Selects a ControlNet model and outputs its filename as both a standard string and a wildcard/combo connection.

• Select Diffusion Model Selects a UNET/Diffusion model and passes its filename as CKPT_NAME and UNET_NAME (useful for context routing).

• UNet Name to CKPT Name Routes a UNET model filename into nodes expecting CKPT_NAME (such as rgthree context nodes).

• Ratio Combobox Dropdown of common percentage presets (10%, 25%, 50%, 100%) converted directly into decimal FLOAT values (e.g., 0.5).

• Central parameter hub configures and routes checkpoint, steps, refiner steps, CFG, sampler algorithm, scheduler curve, and denoise values across workflows.

• Load Checkpoint Hub Pro Central parameter hub that loads a checkpoint and routes MODEL, CLIP, VAE, steps, refiner steps, CFG, sampler algorithm, scheduler curve, denoise values, positive/negative prompts, and metadata across workflows.
