Troubleshooting MiniMax H3 in ComfyUI: Output Generates as a Grid of Tiles
Current-Row-159 · reddit · 2026-08-12
A user running MiniMax H3 video nodes in ComfyUI (on an RTX 4090) encountered an anomalous output issue: instead of a normal video, the generation produced a full-frame grid of small square tiles, looking like a mosaic.
Troubleshooting Done:
- Confirmed the use of the official minimaxh3videovaefp16 (not the audio VAE), which loads fine.
- Hypothesis: The author suspects the H3 latents are spatially tiled, but the decode step either bypasses the video-tiler or hits a generic VAE Decode node that doesn't know how to reassemble them. They are asking the community if this is a missing tiler in the chain, a wrong decode node, or a tilesize/overlap setting issue.
