Delete0AreaFaces

Script for Unity ProBuilder + RealtimeCSG mapping that deletes faces with 0 area (containing NaN tangent coords).

• RealtimeCSG writes NaN to tangent coord space of mesh, causing shaders using normal maps + directional lightmap to spread NaNs everywhere.
• All these faces NaN faces have an area of zero, so this script walks through all faces and deletes them.

Requirement

(Made in Unity 2022.3.13f1)

• RealtimeCSG (used 1.601)
• ProBuilder (used 5.2.2)

Usage

• Put script into any "Editor" folder in Unity (else you can't build).
• Export the RealtimeCSG Model as Unity Mesh.
• ProBuilderize all exported mesh.
• Add the Delete0AreaFaceScript to GameObject that all the meshes are a child of.
• Click the buttons and ez!
