# /3dicon
**One prompt in, a looping animated 3D icon out** (with real transparency) an animated WebP you can drop straight into your app UI.
## Install
 [code] 
One OpenRouter key covers the whole pipeline — the image model and the video
model both run through it.
 [code] 
Put your key in `.env`:
 [code] 
Get one at openrouter.ai/keys.
`ffmpeg` must be on PATH. The first run downloads a ~180MB matting model.
## Use
Ask for it in plain words:
> make an animated 3d fire icon using /3dicon
It generates one still, shows it, and waits for you to approve it before
spending anything on motion. Then it proposes the motion and waits again.
## How it works
 [code] 
The trick is in the middle: **the same still is sent as both the first and the
last frame**, so the model returns to where it began and the loop closes with
no visible seam.
The background is removed against a colour we chose ourselves, which means the
original colours can be solved for exactly rather than guessed — that is what
keeps soft edges soft instead of leaving a halo.
