Browser-native visual tools for 3D & texture artists. Runs locally — nothing leaves your machine, no telemetry, no upload.
3D & UV
- Texture Editor — paint decals, clone-stamp and blur directly on FBX models.
- UV Checker — inspect UV layouts with checker / grid / density / stripe patterns. Optional flatten-to-UV-space view.
Texture pipeline
- Normal Map — generate tangent-space normal maps from height or diffuse. Sobel filter, configurable strength and blur, X/Y invert (OpenGL ↔ DirectX).
- Seamless Maker — turn any photo into a tileable texture via offset-blend or mirror-tile.
- Channel Packer — pack up to four images into R/G/B/A. Presets for ORM, RMA, MRA, HRGM.
- Atlas Packer — bin-packing or grid layout for sprite sheets. Exports PNG + JSON (Agni / Phaser / generic).
Image processing
- Background Remover — local AI background removal.
- Color Replacer — swap a color range. HSL, LAB ΔE, or GPU WebGL shader.
- Resizer — batch resize with Lanczos / Mitchell / Bilinear / Nearest. Modes: longest-side, exact W×H, scale %, power-of-2.
- Mask Generator — compose B&W masks with layers and noise generators (Perlin, Worley, Voronoi, fBm, stripes, dots…).
index.html ~6 KB shell + menu only
css/agni.css ~25 KB shared design system
js/router.js ~6 KB lazy-loads each tool on demand

Initial download is roughly 37 KB (vs. the 216 KB single-file build of v0.4). Each tool then loads its own bundle on click; visited tools stay cached for the session.
Each tool has a hash route — links open the tool directly:

The shell uses ES modules and <script type="importmap">, so it needs a real HTTP server (not file://):
python3 -m http.server 8000
