🧩 Assemble Splat Patches

The last stage of the splat-repair pipeline, and the one with the least glamour. The POC nodes find holes and render repair views; you take those repair images and run them through an image-edit model to fill the holes; and VNCCS_SplatPatchAssemble merges the results back into a single consistent set of images and cameras, ready for a final reconstruction pass. It's the "put it back together" step - without it, you'd have a pile of patched views with no coherent geometry.

Required inputs are exactly what the POC nodes emit: patched_repair_images, repair_camera_poses, repair_camera_intrinsics. Optionally you can also pass in base_repair_images (the unpatched renders, for blending), hole_masks (so the blend knows what was repaired vs original), and the source_images + their cameras if you want the originals included in the combined output.

The two toggles

• include_source (default true) - whether the combined output also contains the original source views. Keep it on if the combined batch is going to drive a full re-reconstruction; you want the originals in there.
• use_mask_blend (default true) - blends repaired and original content using the hole masks, so the seam between "patched" and "already fine" is soft rather than a hard cut. Turn it off if your masks are noisy and are causing visible blend artifacts.

Outputs: combined_images, combined_camera_poses, combined_camera_intrinsics - the coherent, camera-consistent batch you feed into WorldMirror3D/V2_3D (or the WorldGen Build-GS-Data node) to regenerate the splat with the holes filled.

The honest workflow

The full loop reads: POC → render repairs → edit model fills holes → Assemble → re-reconstruct. It's a real pipeline and it can genuinely close gaps in a scene, but every step is experimental and the seams are where it falls apart - if your edit model invents inconsistent content across views, use_mask_blend can't save you. Do a quick sanity render of the combined_images before spending a reconstruction pass on them.

Install

Pack standard:

cd ComfyUI/custom_nodes
git clone https://github.com/AHEKOT/ComfyUI_HYWorld2
cd ComfyUI_HYWorld2
pip install -r requirements.txt
python install.py

Or ComfyUI Manager → HY-World 2.0. The pack's vendored gsplat_maskgaussian fork (from install.py) is required by everything that renders - don't let upstream gsplat sneak in.
