unity-probuilder

Use probuilder_create_shape with a shape type like Cube, Cylinder, or Stairs plus size and position parameters. For multiple shapes, probuilder_create_batch accepts an items array and an optional default parent in one call.

Query the mesh first with probuilder_get_info or probuilder_get_vertices to identify indexes, then apply probuilder_extrude_faces, probuilder_delete_faces, probuilder_move_vertices, or probuilder_weld_vertices with the target name or instanceId.

Yes, the com.unity.probuilder package must be installed. When it is missing, every skill in the module returns a package-missing diagnostic instead of executing any mesh operation.

probuilder_set_material assigns a material or quick RGB color to the entire object, while probuilder_set_face_material targets selected face indexes or a submesh. They are separate skills and not interchangeable.

probuilder_combine_meshes is flagged with Modify and Delete operations, which blocks it in SemiAuto modes. It only runs under Bypass mode or after the user adds it to the Allowlist; the grant flow returns MODE_FORBIDDEN otherwise.

Use ProBuilder when you need editable topology for blockout, level geometry, or mesh refinement. For ordinary primitive objects without editable topology, use gameobject_create instead, since regular meshes do not become ProBuilder meshes automatically.
