MeshCoat

A dedicated 3D texture painting tool for texturing models directly in the viewport. It projects strokes onto UV space without bleeding through thin walls, writing complete PBR material sets in a single pass.

• Direct PBR Painting: Paint Base Color, Roughness, Metalness, and tangent-space Normals simultaneously. Includes material presets and automatic PBR texture-set grouping from standard naming conventions.

• Layer Stack & Masks: Non-destructive layers with live composite blending, adjustable opacity, layer masks, and real-time mirror symmetry along X, Y, or Z axes.

• Painting Toolkit: Full tool suite including Brush (pen pressure, triplanar, UV projection), Eraser, Line, Stamp, Fill Bucket, and an Effects Brush (Blur, Sharpen, Smudge, Pixelate across all active channels).

• Procedural Generators: Built-in Edge Wear and Crevice Dirt wizards for generating real-time procedural weathering, dirt, and edge highlights directly to layers.

• Selection & Stencils: Screen-space viewport stencils, face-selection masking, and whole UV-island isolation.

• Multi-Piece Workflows: Supports multi-object files with dedicated texture sets, layers, resolutions, and isolation modes per piece to prevent cross-painting.

• Import & Export: Loads .glb, .gltf, and .obj formats. Exports native or scaled (up to 4K) maps as individual files or combined atlases, supporting unpacked channels or packed ORM maps.

• Viewport & Lighting: Real-time PBR viewport featuring image-based lighting presets (Studio, Flat, Outdoor, Showcase), wireframe overlays, and isolated single-channel inspection modes.
