What is Draw on a Block?

Paint pixel-perfect textures directly onto 3D models — then arrange them into scenes and keep painting until everything fits together perfectly. No more exporting, tweaking, re-importing, and hoping colors match. Build cohesive modular kits by painting in context, seeing how pieces gel together before you commit.

No bouncing between 2D editors and 3D viewers. Just load a model, paint, and watch your art snap crisply to every face. Whether you're texturing game-ready assets or just playing with blocks, the workflow vanishes so you can focus on creating.

Paint

• Pixel-Perfect Precision — Clean lines, magic wand selection, flood fill, gradient tools, and blend brushes that respect the texture grid
• 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

• Scene Builder — Arrange your painted models on a snap grid to create full 3D scenes
• Shared Textures — Paint any model once, and every instance in every scene updates instantly
• Fork to Customize — Need a variant? Fork a model to paint a unique version without affecting the original
• Export Scenes — Take your creations into Unity, Godot, Unreal, Roblox, or any engine

Import Anything

• Supported Formats: FBX, OBJ, glTF, GLB, Blockbench (bbmodel)
• Per-Material Control — Set resolution and opacity type (opaque/translucent) for each material on import
• Textures Auto-Detected — Existing textures are imported as your base layer
• Export Anything — Export just textures, or include your model in FBX, OBJ, glTF, GLB, and Blockbench (bbmodel).
