MiniMax H3 seed consistency issues across resolutions in ComfyUI
StuffCapital7395 · reddit · 2026-08-21
A user reported a consistency issue with MiniMax H3 (ref2va) in ComfyUI when changing resolutions.
- The Problem: Generating a draft at low res (0.4MP) and then upscaling to 1MP with the same seed results in completely different composition, action, and camera motion.
- Troubleshooting: Swapping image reference sizes did not preserve the composition.
- Technical Inquiry: The user suspects this is due to spatial attention shifts in the DiT architecture and asks if specific latent upscaling workflows exist to maintain consistency.
