MiniMax H3 Ecosystem Roundup: ComfyUI 0.36 and a 4.5GB VRAM Text Encoder Swap
optimisticalish · reddit · 2026-09-17
A community roundup of the MiniMax H3 ecosystem from r/comfyui (Sept 16):
- ComfyUI Portable 0.36.0: fixes H3 Fun Controlnet with the Comfy Compiler, adds a Video Concatenate node, and optimizes MiniMax H3's Video VAE memory usage; two official workflows for the 'Fast H3' DMD2 variant.
- FaceSwap LoRA: for MiniMax H3 Ref2VA, swaps the reference video's identity face using reference images (trigger word faceswap), requires the updated CRT-Nodes pack.
- ClipProj v3.1: projection matrices let a small Qwen3-VL replace H3's 32B text encoder, cutting VRAM from 15.7GB to 4.5GB with 29% fewer phoneme errors (60–74% fewer in Spanish/French/German/Italian).
- Screenplay prompt engine v1.0: multi-format timeline exports (.EDL, .FCPxml, .CSV, .MD) for DaVinci Resolve and Final Cut Pro.
- New LoRAs: retro 70s cel-animation style and a Halloween 'ghost out of thin air' effect.
