Meet Hydra+: The Same Animation, Finer Detail#
Hydra+ is a new animation model in the Sprite Generator. It animates exactly like Hydra - the same motion, the same timing - and adds a final pass that keeps your sprite's fine detail sharp from the first frame to the last. Already have a Hydra animation you like? Improve Details gives it that same pass in one click.
The key facts
- Hydra+ is in Animate, Keyframe Animation and New Direction, at 4 credits per second, for animations from 3 to 5 seconds. Like Hydra, it generates a sound track timed to the motion, and it takes a little longer to generate.
- Improve Details runs the Hydra+ pass on an animation you already made with Hydra, for 1 credit per second of animation. There is no prompt to write, and the motion stays exactly the same.
- Hydra plus Improve Details costs the same as Hydra+ in one go: 3 + 1 = 4 credits per second. So you can keep animating on Hydra and add the detail only to the animations that need it.
Same animation, finer detail
To show the difference with nothing left to chance, we animated a knight once on Hydra, with the prompt "very subtle idle, standing perfectly still, chest rises and falls slightly, cape barely moves", then ran Improve Details on that exact animation. Same frames, same motion. The only thing that changes is the detail.

Freeze a single frame and the difference is in the small things: on Hydra+ the face under the helmet has a drawn eye and brow, the cheek guard picks up its engraving, and the scrollwork on the shoulder plate comes back crisp.

It works the same way on a swordswoman in a patterned kimono: separate strands of hair, crisp line art around the eye, the wrap on the katana's handle.

Which animations gain the most
How much Hydra+ adds depends on your sprite. The more fine detail it carries - engraved metal, patterned fabric, thin line art, small faces - the bigger the difference. When Ludo spots fine detail that got softened during a Hydra animation, Improve Details moves up to the main buttons on that animation's card, so you can tell at a glance which ones are worth improving. On every other Hydra animation, it waits in the card's ⋮ menu.

Try it
To animate with Hydra+ from the start, open the Sprite Generator, pick Animate, Keyframe Animation or New Direction, and choose Hydra+ under Model.

To improve an animation you already have, hover over any Hydra animation in your grid and click Improve Details, on the card or in its ⋮ menu. The improved version arrives as a new animation in your grid, and the original stays as it was, so you can compare the two.
