First off, if I set the terrain length and width too 2048x2048 and then place a mat over the terrain of 2048x2048 the terrain is going to look pretty good as long as that mat of the original image lets say is of good quality.
Now if I set the terrain to 50,000x50,000
What size do I make the terrain image so I can create the mat file so when placed over the 50,000x50,000 the quality is still pretty good?
Thanks
