CellPrefabPainter is a tool designed for easily painting Prefab objects. Its main features include simplicity and seamless integration with InstanceCollector. The editing process is as follows: first, generate some brush Prefabs; then, use the brush tool to paint objects on the scatter target, collecting them into a CellHolder. Finally, you can place these reusable CellHolder templates in the scene.
