ComfyUI Node
HiCache Accelerate (Hunyuan3D)
Training-free acceleration of Hunyuan3D shape generation: skip DiT forwards and forecast the flow-matching velocity instead (HiCache Hermite / HiCache++ DMD, via the hicache-pp library).

Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| pipeline | HY3DMODEL | Hunyuan3D shape pipeline from Hy3DModelLoader (kijai/ComfyUI-Hunyuan3DWrapper). | |
| method | COMBO | hermite | Forecast basis on skipped steps: hermite = HiCache (polynomial, arXiv:2508.16984; best measured quality inside ComfyUI) dmd = HiCache++ (exponential / Prony-DMD; worth trying at large intervals on the big 2.1 DiT) auto = holdout-pick the better of the two per compute step |
| interval | INT | 31–12 | Compute one DiT step, then forecast interval-1 steps. 1 = caching disabled (every step computed). Measured sweet spot inside ComfyUI: hermite interval 3. |
| warmup_steps | INT | 20–100 | Always compute the first N sampling steps before any forecasting starts. |
| enableopt | BOOLEAN | true | Off = remove the patch and restore the original DiT forward. |
| max_orderopt | INT | 11–4 | Highest Hermite / finite-difference order (hermite method and warm-up fallback). |
| sigmaopt | FLOAT | 0.500.05–0.95 | Hermite contraction factor in (0,1); keeps high-order terms bounded. |
| dmd_historyopt | INT | 53–16 | DMD snapshot window length (dmd/auto methods). |
