Hmn, sounds like a terrain issue, if you go into test mode, change the terrain, then come out again, does the terrain show up then?
Try moving your terrainbank folder elsewhere (to keep as backup), and then checking your files via steam to redownload the now missing files, and see if that makes a difference.
I know you have checked your files etc via steam already, but sometimes if you have a corrupted file steam will not realise and think you have the file and not redownload it, but if you delete or move it then steam will detect it and redownload it.
Also, just to clarify. You say in your earlier post you have the same issue, but ..
OP: His frame rate is less than it was before validating his files, and after multiple validations it is getting lower each time.
You: You validated some time ago and now your editor is corrupt and showing a black screen instead of the terrain, and validating doesn't fix it.
How are these two issues the same? Or do you mean that you are experiencing the same FPS drop after each validation on top of having a black editor?
Just wanted to clarify so that if they are separate issues they wouldn't get confused while troubleshooting.
