ComfyUI Node
MiniMax H3 Sigma Scheduler
Builds an explicit MiniMax H3 Base FL2VA or Ref2VA video sigma schedule; the scheduler selector includes experimental ComfyUI-native alternatives that require an already-shifted H3 MODEL; the optional turbo selector is Experimental — community, unsupported and only constructs sigmas. Load any matching community LoRA separately in the host workflow.

| turboopt | COMBO | disabled | Turbo LoRA (Experimental — community, unsupported). Select an exact recipe; the Scheduler does not load or patch a LoRA. |
| recipe_idopt | COMBO | disabled | Legacy recipe_id compatibility alias for the experimental turbo selector; prefer turbo. |
| scheduleropt | COMBO | h3_endpoint | Scheduler (Experimental for native choices). h3_endpoint preserves the Sigmax compatibility schedule; all other choices require an already-shifted MiniMax H3 MODEL and delegate to ComfyUI. |
