I have terrain (ANT Landscape plugin) that I would like to cut up into chunks (don't need to be equal size) for a game engine so that I can do occlusion culling / or load and unload chunks around the player.
I am trying the knife project feature that I saw in the answer here but it doesn't work for my terrain mesh (using the terrain plugin).
I also tried some answers here that contain some Python scripts, but couldn't get them to work.
Any ideas of how I can cut the mesh up quickly in to chunks. I've been doing it manually so far, but it takes forever to do as some terrains can be rather big. I don't mind having to do a little clean up of the mesh after.
Picture below shows the knife project method (following instructions from linked answer).
Example of mesh (terrain is usually much large than this) that I am trying to break into chunks.
How I am manually doing it.
