zwcloud: This issue is caused by duplicated name when converting a mesh to mesh-terrain.

  2. Convert another mesh to mesh-terrain and use the same output name
  3. Then try to convert again, see the error below and becomes unable to use MTE converter
  4. Restart Unity won't fix the issue

Environment

Your solution or workaround
Use a different name for when convert another mesh.

We should not allow conversion if target mesh-terrain already exists and notifiy the user about it.

Whatever, the specific exception still needs to be inspected.
