Paint System is an add-on for non-photorealistic rendering (NPR) that enables users to paint directly onto 3D objects in the viewport. It provides an immediate texturing workflow as an alternative to complex node setups or Grease Pencil techniques.

The tool includes support for ambient occlusion and light layers to assist in developing stylized textures. It also features automated baking and texture exporting functions, streamlining the workflow for transferring painted models from Blender into game engines.
