Viggle-Animate — ComfyUI conversions

ComfyUI-native conversions of Viggle/Viggle-Animate — a 33.1 B full finetune of MiniMax-H3's ref2va transformer for character replacement in video: a driving clip provides motion, camera, background and lighting; one reference still provides the character. No text encoder — conditioning is a frozen 362-token embedding. The sampler is DMD2-distilled: 4 steps (3 forward passes).

Workflow Notes

• Custom nodes required: ComfyUI-Viggle-Animate-H3 (Viggle Animate Conditioning + Load Text Conditioning) and ComfyUI-KJNodes (fast preview).
• Load Video: set frame_load_cap equal to the conditioning node's length (e.g. 124) and force_rate to 24.
• Output resolution follows the driving video by default; set the conditioning node's width/height to override (each axis rounds to 32), or pre-scale the clip with Scale Image to Total Pixels. Tested canvas range: 0.4–0.98 MP.
• Sampler: euler, er_sde, exp_heun_2_x0, lcm, simple, normal, beta, bong_tangent, 4-8 steps, cfg 1.0, ModelSamplingMiniMaxH3 shift 3.0.
• Stacks with Comfy Kitchen and block sparse attention patches.

Limitations

• Identity drift on re-entry: when the subject leaves the camera view and re-enters, the re-entry settles toward the driving video's original appearance rather than the reference image. The same applies when the subject moves far from the reference pose or makes abrupt large motions (e.g. a backflip) — the further from the still, the weaker the identity hold.
