Asset Brush is an add-on that enables users to populate scenes by painting objects and assets directly into the 3D Viewport. It features seamless integration with Blender's native Asset Browser, allowing assets to be sent directly to the active brush tool. The tool includes multiple placement modes such as paint, line, grid, and scale.

Assets can be organized into categories to streamline the painting process, with options to randomize placement from an active category or specify targeted deletions. The tool applies global asset settings to control distance, scale, randomness, orientation, and offsets. It also supports pen pressure input, stroke-direction object alignment, and displays a visual brush cursor overlay.
