Minimax H3 local runs full of artifacts: ComfyUI workflow troubleshooting
Dendwdls · reddit · 2026-09-09
A user with 16GB VRAM / 64GB RAM locally generating a 10s Minimax H3 video (woman playing with a cat, then zoom to a phone) reports heavy artifacts, broken faces, and a background that drifts with camera movement, taking 20+ minutes per run. The workflow uses rf2va plus an 8-step LoRA with a character sheet and location image as references; they posted the full workflow link asking whether the workflow or the prompt is at fault.
