Brush-Based Placement of Meshes
Cluster Editor is a convenient tool for brush-based placement of meshes baked into Mesh Clusters directly in the scene. It allows editing the existing Mesh Clusters and creating new ones.
Cluster Editor is available when the Cluster Paint Mode is selected on the toolbar.
Switching to Cluster Paint Mode opens the Active Tool window:
In the Objects section, there is a list of all Mesh Cluster objects available in the world. Similarly to the World Hierarchy window, you can organize the nodes:
- Select one or several nodes.
- Toggle the nodes on and off.
- Filter nodes by name.
- Rename a node by double-clicking on it.
- Toggle the Spawn When Drawing flag.
To edit the required Mesh Clusters (one or many), select them either in the Objects section or in the World Hierarchy window and specify the Objects settings.
For convenience, the Create New Cluster button, a shortcut to manual creation of Mesh Clusters, is available right in the Active Tool window.
