OK, here is the .ter file moved over and opened in TG2, wow its really different!
But this is so fun, I had no clue you could move a render from TG1 to 2 and open it up!
David clued me in.
I have to move the renders over to the new Mac, as the old one has TG1 on it and the new Mac has TG2.
Now I need to figure out why the actual topography is so different? Camera angles, whatever, heavens this is fun!
