That wasn’t possible in the version on GitHub, I’ve updated it with a new version that makes this possible, just toggle “showDebugColors” in the material.
I’ve also updated the way tiles get rotated if “rotateTiles” is turned on, now each tile gets a random rotation (before it was fake rotations which were basically just mirroring the texture coordinates on different axis and it was always the same for each kind, so all green tiles used to be rotated 180 degrees for example).
I also wanted to try using this with virtual textures, but the current implementation of virtual textures is not yet suitable for landscapes which is my main use case for this material.
