Blender users who enjoy procedural tinkering and material painting but dread shader graphs, UV unwrapping, or node spaghetti might want to peek at a tool that skips all that. A new, free tool by Manuel de Jorge enables painting PBR materials directly in Blender’s 3D viewport—without needing UVs, textures, nodes, or even lighting setups. The painter’s playground is immediate, shader-free, and aimed at creative speed, not technical overhead.

The tool uses MatCaps (short for Material Capture), a long-standing method in 3D to display materials based on captured lighting and surface information. While typically used for viewport shading, Manuel’s tool takes it further by letting you blend multiple MatCaps together, in layers, using a brush-based interface. Think of it as painting with lighting and material response baked in—ideal for concepting, prototyping, and lookdev work.

PBR without the pipeline

This tool bypasses the conventional PBR workflow, ditching texture slots and node setups. Instead, you paint directly onto the object in the 3D viewport, and what you see is what you get. The approach is non-destructive and designed to be artist-friendly, with each brush stroke adding to a stackable layer of material behavior. The MatCaps come bundled, and you can add your own.

No shader graphs. No UV maps. No BSDFs to troubleshoot. Just pick a MatCap, paint, blend, repeat. The idea is not to replace proper texturing workflows for production—this is clearly a conceptual tool for look development and exploration, not a final delivery solution. But for rapid prototyping or quick shading mockups, it saves time by cutting out setup overhead entirely.

Brush-based blending and fast feedback

The system allows you to blend MatCaps using custom brushes, offering a painterly way of designing complex material appearances. Since everything runs directly in the viewport, feedback is immediate, even for more complex materials. Think speed-painting with photorealistic materials—without fiddling with node graphs.

The tool is free, but where’s the catch?

No catch. The MatCap painting tool is free to download in beta and available on Gumroad. It’s “a quick and dirty” solution, with no UVs, no lighting, no shaders—just results. The author notes that this is a one-man project, so expect some rough edges, no tech support, and a lot of freedom to experiment.
