Hi, so you sent me a picture showing that the blue brush marker does not line up with the mouse pointer. Unfortunately I don't know what might cause this (I haven't seen it myself). Can you get any clues by testing any of the following:
- Does anything change when clicking to modify the terrain?
- Does the mouse work correctly in run mode instead of edit mode?
- Does it work when using one of the colored cubes examples instead of the terrain examples?
- Does the incorrect mouse move with a constant offset, or does it change as the mouse moves around?
Not sure these will help, I'm a little stumped to be honest!
