Custom Mesh Volume

The Custom Mesh shape uses a Static Mesh asset as the selection volume. The plugin extracts the mesh's convex collision hulls to define the selection boundary — perfect for non-rectangular selection shapes.

Activate​

Press C or select Custom Mesh in the Shape dropdown.

Setup​

  1. A Source Mesh asset picker appears in the control panel.
  2. Select any Static Mesh from your project.
  3. The mesh's collision geometry defines the selection volume.
warning

If the selected mesh has no collision setup, the plugin falls back to using the mesh's axis-aligned bounding box (AABB). A warning is displayed in orange in the panel:

"Warning: mesh has no collision setup. Using bounding box as fallback."

For best results, make sure your mesh has convex collision set up in the Static Mesh Editor.

Selection behavior​

  • In Intersect mode: selects if the actor's bounds overlap the convex hull(s)
  • In Contain mode: selects only if the actor's bounds are fully inside the convex hull(s)
