probuilder-delete-faces

You can delete specific faces from a ProBuilder mesh in Unity by targeting them with explicit face indices or semantic direction selection. This streamlines mesh editing workflows by allowing programmatic removal of individual or multiple geometry sections.

Yes, you can remove ProBuilder faces by semantic direction like Up, Down, Left, Right, Forward, or Back. This semantic selection method allows you to quickly target and delete mesh faces without needing to manually identify explicit index numbers.

To programmatically edit ProBuilder mesh geometry, you need access to the Unity Editor API and a target GameObject with a ProBuilderMesh component. These prerequisites allow the Skill to interact with and modify the mesh within the Unity scene editing environment.

The best way to clean up internal wall sections or bottom faces in Unity 3D modeling is using semantic direction face deletion. By selecting faces based on their direction, environment designers can efficiently batch remove unwanted geometry from ProBuilder meshes.

When using explicit face indices to remove ProBuilder mesh geometry, the limitation is that you must know the exact index numbers beforehand. If the mesh structure changes or indices shift, you may need to use semantic direction selection as a more reliable alternative.
