Draw on a Block

Painting that's fun and productive.

Draw on a Block is a pixel-perfect 3D texture painter. Paint directly onto models, arrange them into scenes, and keep painting until everything fits together. No UV unwrapping. No bouncing between 2D editors and 3D viewers. Just load a model and start creating.

Paint

Paint textures directly on 3D surfaces with tools that snap to the texture grid.

• Pixel-Perfect Tools — Brush, line, shape, flood fill, gradient, magic wand, and blend brushes

• Up to 16 Layers Per Material — Real-time compositing with visibility toggles, merge, duplicate, and reorder

• Multi-Material Models — Paint models with multiple materials, each with independent layers and resolution

• Texel Grid Overlay — See exactly where each pixel lands on the 3D surface

• Explode View — Pull apart complex models to reach hidden geometry

Build

Arrange your painted models on a snap grid to create full 3D scenes — then keep painting them in context.

• Scene Builder — Place, rotate, flip, and duplicate models to build complete scenes

• Shared Textures — Paint any model once, and every instance in every scene updates instantly

• Paint in Context — See how your pieces gel together before you commit

• Fork to Customize — Need a variant? Fork a model to paint a unique version without affecting the original
