MiniMax H3 local full-body shots suffer face distortion, likely due to VRAM limits
Loud-Guitar1920 · reddit · 2026-08-12
A user testing MiniMax H3 locally in ComfyUI reports severe face distortion in full-body shots. Running the model on an 8GB RTX 4070 Laptop GPU, the faces become soft and unrecognizable during movement.
Despite extensive troubleshooting—including testing both I2V and Ref2VA workflows, adjusting resolutions (480p and native 1344×768), and using static cameras—the issue persists. The user noted that a paid 2K API test preserved the face correctly, suggesting the local problem stems from resolution constraints or model precision (like int8 quantization). They are seeking advice on viable local workflows to maintain face integrity.
