It denoises directly in high-resolution pixel space and produces a super-resolved image in one pass. This repository hosts the released decoder checkpoints, plus the encoder/decoder ("VAE") weights they depend on. To install the ComfyUI-PiD custom node and utilize its automated model downloader, follow these steps specifically tailored for the ComfyUI Windows Portable environment.<h3 id="1.-custom-node-installation">1. Custom Node Installation</h3>Do not just drag and drop files. For a portable installation, you must use Git to ensure the node's internal structure and submodules remain intact.<ol><li>Navigate to your <code>ComfyUI_windows_portable</code> root folder.</li><li>Open a terminal (CMD) in this folder.</li><li>Navigate to your <code>custom_nodes</code> directory:DOS<pre><code>cd ComfyUI\custom_nodes
</code></pre></li><li>Clone the repository:DOS<pre><code>git clone https://github.com/Merserk/ComfyUI-PiD
</code></pre></li><li>Return to the root folder:DOS<pre><code>cd ..\..
</code></pre></li><li>Install the required dependencies using the embedded Python:DOS<pre><code>.\python_embeded\python.exe -m pip install -r .\ComfyUI\custom_nodes\ComfyUI-PiD\requirements.txt
</code></pre></li></ol><h2 id="link-to-z-image-base-model-files:">LINK TO Z-Image Base Model Files:</h2><a target="_blank" rel="ugc" href="https://civarchive.com/models/2342907/rebels-z-image-base">https://civarchive.com/models/2342907/rebels-z-image-base</a><h3 id="2.-using-the-auto-download-feature">2. Using the Auto-Download Feature</h3>The PiD nodes are designed to pull models automatically upon the first execution of a prompt.<ol><li>Restart ComfyUI completely.</li><li>Load a workflow that utilizes the PiD Decode or PiD Prepare nodes.</li><li>Ensure the <code>auto_download</code> parameter is set to <code>True</code> in the node properties.</li><li>Queue your prompt.</li><li>Monitor the Terminal: Watch the CMD window. You will see HTTP requests appearing as the node validates and begins downloading the required weights from Hugging Face.</li></ol><h3 id="3.-troubleshooting-&quot;stalls&quot;">3. Troubleshooting "Stalls"</h3>Because there is no progress bar, a silent CMD window can look like a stall. However, if the download actually hangs (no new <code>INFO</code> lines for 5+ minutes):<ol><li>Kill the Process: Close the CMD window completely to force the download attempt to terminate.</li><li>Restart ComfyUI: Open the terminal and restart ComfyUI to clear the failed request from your GPU/Network cache.</li><li>Disable Auto-Download: Before queuing again, go into the <code>PiD Decode</code> node settings and set <code>auto_download</code> to <code>False</code>.</li><li>Verify/Retry: With <code>auto_download</code> set to <code>False</code>, the node will skip the network request and attempt to load existing files. If you suspect the download partially finished before stalling, check <code>ComfyUI\custom_nodes\ComfyUI-PiD\vendor\PiD\checkpoints</code> to see if a folder has been created. If it is empty or incomplete, remove that partial folder before trying the download again.</li></ol>Pro-Tip: If the auto-downloader consistently fails, it is usually due to network timeouts on large files. If this happens, you must perform a manual download once to place the <code>.pth</code> file into the <code>vendor</code> directory as described in the repository's documentation. Once the file exists locally, you can keep <code>auto_download</code> set to <code>False</code> permanently.
