Grass is not expressed neatly on the border of the material

Grass grows through the wall. How can I fix this? Should I change my sketchup model?

  1. can you provide a close-up?
  2. can be happening that your 3d model is not correct.
    2b. maybe the face of your 3d model is incorrect and need to be switched.

Hello, sorry for your problem. I would suggest you to check your model to see if there is any problem with the model being resurfaced or being interspersed.
