🎬 Studio42 PatchDrop

Studio42 PatchDrop is the second half of the pack's lift-and-drop pair: it takes a patch image and places it onto an original image at pixel-precise coordinates, with masks, blend modes, opacity, feathering, scaling, rotation, and shape-aware placement. It's the node that makes a pasted-in element look placed instead of pasted.

The classic workflow: lift a patch with PatchLift Loader (which hands you x/y/width/height), do something to it, and wire the coordinates straight in here. But it also stands alone - drop a logo, replace a face region, composite a cutout from the Background Remover. If you're building a workflow where "put thing here, exactly" is the requirement, this is the node.

What you set

• original_image and patch_image - the base and the element.
• patch_x / patch_y - drop coordinates, ±2048/4096.
• patch_mask - optional MASK for transparency control (essential for non-rectangular patches or cutouts).
• patch_width / patch_height - target size (16–1024), with resize_patch controlling whether the patch is actually resized to fit and preserve_aspect to keep proportions.
• patch_shape - rectangle, circle, or rounded_rectangle, with corner_radius.
• blend_mode - 9 modes (normal, multiply, screen, overlay, soft_light, hard_light, difference, lighten, darken).
• opacity - 0–1.
• feather_edges - 0–50, the "make the seam disappear" control. This plus a soft blend mode is how pasted things stop looking pasted.
• scale (0.1–3) and rotation (±360°).
• position_mode - use_coordinates, center, or manual (the last two override with presets or manual_x/manual_y).

What comes out

result_image (the composite), placement_mask (the mask of where the patch actually landed - great for debugging or reuse), and preview_image (with overlay indicators).

The honest tips

• Feather 5–15 and soft_light/overlay are the pack's own recommended starting point for integrated patches; normal + opacity for straight placement.
• Keep resize_patch off when you want the original quality preserved.
• position_mode: use_coordinates is what respects the PatchLift outputs; the other modes override them.

Installing it

Same pack, 24oiduts-ComfyUI:

• ComfyUI Manager: search 24oiduts, install, restart.
• Manual:

  cd ComfyUI/custom_nodes/
  git clone https://github.com/GeekyGhost/24oiduts-ComfyUI
  pip install -r 24oiduts-ComfyUI/requirements.txt

  then restart.

Pillow/numpy only. The GitHub README is a stale Studio42 template with a "WIP" banner - ignore it.

Troubleshooting

• Patch lands in the wrong place - position_mode isn't use_coordinates, or you're feeding manual x/y that override it.
• Hard edges - no feather, or the mask is missing for non-rectangular shapes. Add feather_edges and a proper patch mask.
• Patch stretched - resize_patch on with preserve_aspect off; either is fine, just know which you want.

The drop node you'd actually keep in a workflow - coordinates in, placed-and-integrated image out.
