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.

Looks cool. Does it also improve the sound effects for these things? I couldn't tell in the clips but it seems the gunshot sounds are still lacking. H3's sound effects for certain content (like this) are laughably weak.
Do punches actually sound like punches? Slaps like slaps?
I haven't added any sound Effects into the training of the beta, so there is no improvement, still stock Sounds. It was mostly Impacts and Camera Move related Training Material. But that could be a good Idea for the next Version. Thanks.
would be cool to get a lora for slaps/smacks/claps for.. reasons!
@snake88 since this is an impact lora, it could already make the claps and smacks better.
@Leechtm Would be awesome to hear proper sound effects to go along with these proper impact effects! Hope you'll consider it. Either way, great job. Super fun LoRA!
@drowai443 yeah, proper sounds are on the list for the next version :) glad you enjoy it.
getting 'one step closer' to creating an anime music video of ai vids.
Didn't test it but your description is very fun XD
finally , the era of anime battle power scales with animations
This works really well for making bodies collide with each other in other ways outside the realm of punching and kicking...
well, impacts are impacts, haha.
Did you train this on civitai? Mine keeps failing, it defaults to like 3000 steps and 10 epochs. I feel like 3000 is wayyy too high. what do you recommend? im training with just 6 videos.
this has been trained on runpod / Ostris Aitoolkit on a A6000 with 48gb VRAM. So, not the biggest, not the smallest card. took about 14 hours. 35 Videos, ranging from 5 to 15 seconds. 4000 steps. The Lora is step 3250. After that it was overcranked.
@Leechtm ty
It works alright but getting kinda blurry result. What strenght do you recommend? Did you use it with or without turbo lora? This information would be appreciated.
Its still an Alpha. If you stack loras, it gets blurry. I used turbo lora with the ref model, 1.0 Megapixel, 10 steps. Bf16
Incredible, thank you!
Any example workflow?
no need, just add the Lora in its normal place, start with 0.75 strength and work your way up.
Looks good! Looking forward to this evolving more to capture fight physics.
not sure if i add fight physics into it. Theres a Lora called Combat which does that really well already.
This is already works, pretty well. Looking for the next version. Thank you!
working on it :)
Amazing, it makes every dynamic interaction, well... more dynamic, lol.
it does :)
Thanks for sharing! I also noticed that this LoRA works surprisingly well for sex scenes—it makes the sexual movements much more intense, and even seems to enhance the fluid effects. What a magical LoRA!
I actually haven't tested it on sex scenes. But if this works, I can see 🙈 f the next version can have a bit more spice in it.
