SMACK — punches, impacts & gunshots

Beta 1 · MiniMax H3 (Ref2V)

MiniMax H3 can already do impacts. It just does them politely.

SMACK fixes that. It takes every kind of impact — fists, weapons, gunshots, car hits, falls and hard landings — and gives it weight, follow-through and consequence. Bodies react like they've actually been hit instead of gently acknowledging it. Pair that with a camera that moves like someone was paid to operate it, and you get a shot that looks staged by a stunt team rather than caught on a $50 phone.

What it does

Intensifies impacts of all kinds: hand-to-hand, weapons, gunshots, vehicle collisions, falls and landings

Stronger, more deliberate camera work — dynamic moves, aggressive angles, real reaction to the hit

Pushes the whole shot toward a Hollywood action grammar instead of flat, generic default motion

Training

Trained on 35 clips of impacts and dynamic camera moves, on MiniMax H3 Ref2V.

Usage

No trigger word. Use it with the REF MODEL. Just load it and describe your shot as usual — the LoRA does the seasoning.

Beta notice

This is Beta 1. It's already good enough to be worth releasing, but it's not finished. A larger, more varied dataset is in the works and the next version will follow once I have more material. Feedback on where it over- or under-cooks a hit is genuinely useful at this stage.
