ComfyUI 0.33 Breaks H3 Motion Context, Fix Released and Upstream Changes Explained
Sad_Berry_4621 · reddit · 2026-08-15
After updating to ComfyUI 0.33, the H3 Motion Context plugin fails with 'layout patch could not be applied'. The author confirms it's a plugin issue and has released a fix.
Upstream changes: 0.33 natively supports anchoring keyframes at any frame, adds Add Guide for MiniMax H3 node, and fixes a bug where reference images wiped keyframe latents. Some plugin features are now redundant.
Features still worth installing: Latent passthrough to avoid color drift, and audio continuation across joins.
Future plans: Rebuild on the new public keyframe format to stop monkey-patching internals.
