size_x = 936.3456
size_z = 234.0864
scale = 30
In Mapview & Tracked only shows left half of map in surface mode
and right half is discolored in materials mode
In 3d mode in mapview,Tracked, and ingame only renders when looking in a certain direction.
I think, for rectangles, only 2k x 4k / 1k x 2k is possible etc. I don't think 1k x 4k is possible.
The straight rhythm terrain is 4097x257 and is correctly rendered.
Please make sure to use the latest version of the track tools.
My bad for spreading invalid information. I didn't know this was possible!
