Load PSD

ComfyUI's built-in LoadImage can't read a PSD, and until recently nobody was too bothered - you'd just flatten and export. But once you've got a 40-layer document from a designer, flattening before you even start is throwing away the one thing that makes the file useful. Load PSD is the front door for the layered half of the Photoshop Bridge pack: it pulls a .psd, .psb, .tif, or .tiff straight out of ComfyUI's input folder, gives you a flattened IMAGE + MASK to run your generation on, and hands you the file's actual layer stack as a LAYERS output you can rearrange, process, or write back out as a real layered PSD.

What you get

• IMAGE - the flattened file (via the PSD's embedded Maximize-Compatibility composite, falling back to psd-tools' own recompositing).
• MASK - transparency as 1 - alpha, all zeros if there's none.
• LAYERS - the real stack: every layer's pixels, name, position, opacity, blend mode, and visibility. This is ComfyUI 0.31+'s first-class LAYERS type, so it plugs straight into core's Create Layered Image node (the full-screen layer editor) or into this pack's own Compose Layers to PSD to write a layered document back out. On pre-0.31 ComfyUI it's still just a socket type, so Load PSD → Compose round-trips with nothing else installed.

A few honest notes on the layer output: text and smart-object layers arrive rasterized, adjustment layers are skipped (both logged), and ComfyUI composites blends in linear space while Photoshop uses sRGB - so arrangement carries over exactly, but partial-opacity and non-normal-blend pixels render close to, not identical to, Photoshop. The written PSD in Photoshop is always the authoritative render. And 16-bit/CMYK/Grayscale/Lab files get converted to RGB8 on the way in.

The widgets that matter

• psd - a dropdown of every accepted file in the input folder. TIFF loads fine; .ai and camera raw deliberately don't (they route through Photoshop itself).
• edit_original - off by default, edits save to a safe copy and your original is never touched. Turn it on and right-click Edit Original in Photoshop to save back into the very file you loaded.
• on_save - what a save does: Re-run workflow (default), Update only (don't re-run) (picks up the edit without firing the graph), or Ignore - useful when you want to open the PSD, shuffle layers, and push one back without the graph re-running on every save. It's enforced server-side, so it governs the plugin's Send button too.
• flatten_groups - off lists every layer individually (group opacity/visibility applied to its members); on collapses each top-level group into one layer.

Install

Same as every node in this pack - Manager → Install via Git URL, or:

cd ComfyUI/custom_nodes
git clone https://github.com/ericpaulsnowden/comfyui-photoshop-bridge.git comfyui-photoshop-bridge
pip install -r comfyui-photoshop-bridge/requirements.txt

…with ComfyUI's own Python, then restart. The plugin is optional for loading - that's all server-side. Round-tripping an edit back uses Tier 1 (file watch) without it, instant + cross-machine with it. Pre-1.0 and actively developed, so expect the odd breaking change; the author ships annotated example workflows including a load-psd-start-a-workflow.json and a layered round-trip you can load straight into ComfyUI.
