HELP! Landscape Target layers wont show and preview is always black

Hello,

I’m currently taking an environment course and the instructor wont respond. I have 2 major issues and I cannot continue on the course until they’re figured out.

  1. Landscape target layers will not show up at all in the paint section or any where on the main level for that matter.

  2. Materials in preview mode show as being black and will not change no mater what I do. I do have preview weight turned up.

Thank you any help is appreciated.
