Check the Area

  • Select the Vegetation Area. Check that it is enabled and covers the place where you want to paint.
  • Assign a Type Set with at least one valid sprite. Check its material and sorting layer.
  • Paint a few plants near the camera before increasing the amount.

Check the project

  • Use URP with a 2D Renderer. Read the first Console error if vegetation is pink or missing.
  • Keep World Data and its .meta file. Runtime Data and the atlas can be rebuilt; World Data stores your plants.
  • Try a Player build as well as Play Mode. Follow Testing Your Game for a short checklist.
