Hand-painted 3D texturing, vertex normal editing, and dynamic symmetry—right in your browser.

Stylized Paint Core is a lightweight, single-file 3D texturing application custom-built for game artists, digital sculptors, and indie developers who love hand-painted art. Designed from the ground up to solve the friction points of traditional texturing pipelines, it allows you to paint seamless world-space brushstrokes across complex UV seams with zero setup time.

Key Features

• World-Space 3D Painting: Strokes are projected dynamically onto your model using a world-space sphere brush. Paint flows seamlessly across UV seams and handles stretched geometry naturally, while back-face angle limits keep paint from bleeding through thin surfaces.
• Pinnable Dynamic Symmetry Plane: Break free from locked world coordinates. Pin a symmetry plane anywhere on your model using volume raycasting, dual-point picking, or edge/edge-loop snapping. Perfect for painting off-center armor pauldrons, gauntlets, ears, or limbs symmetrically.
• Stylized Vertex Normal Editing: Direct light flow and shape custom shading directly on your mesh. Soften low-poly foliage, direct character highlights, or bend vertex lighting without adding geometry or opening complex DCC software.
• Artist’s Color Wheel & Dynamic Harmonies: Features an integrated RYB painter's color wheel with real-time color harmony presets (Complementary, Triadic, Analogous, Split-Complementary) and a value ramp tuned for cool shadows and warm lights.
• Layer Stack & Generator Suite: Includes non-destructive layers with essential blend modes (Multiply, Screen, Overlay, Soft Light, Erase, etc.). Bake foundation maps directly inside the app with one click—including Ambient Occlusion, Light Bake, Edges & Cavities, Height Gradients, and World Noise.
• Dual Viewport & UV Editor: Work simultaneously in a real-time 3D viewport and a synchronized 2D UV canvas. Features cross-highlighting, UV mirroring, and specialized UV gradient fills.
• Zero-Friction Stencil System: Import and place screen or UV stencils directly over your viewport with intuitive scale, position, and rotate controls—no sub-menus required.
• Built-in Starter Presets: Jump right into painting with built-in sandbox scenes, including a flat canvas, an interior diorama room, spheres, cylinders, rounded cubes, and demo models.

Technical Specifications & Export

• Format: Single HTML file (index.html) running locally in modern desktop browsers (Chrome, Edge).
• File Support: Import .glb, .gltf, .obj (with .mtl), and .fbx models.
• Export Options: Export packed .zip archives or individual files including base color maps, normal maps, transparent layer PNGs, and updated .glb models with edited vertex normals.
• Project Saving: Full non-destructive project saves (.spaint) with session auto-restore.
