Lemme check
You sent me a link to a empty zip file :c
Also, I have some questions about this, here is the coverage code for the 2x2 ramp:
0
COVERAGE: //TBNESW
1 : 2
1 : 4
0 : 6
0 : 6
1 : 6
0 : 6
And here's the same area from the 2x2x3 corner:
2
0 -0.5 0
2 1 9
-0.5 0.5 0
1 1 9
COVERAGE: //TBNESW
0 : 999
0 : 999
0 : 999
0 : 999
0 : 999
0 : 999
What's that stuff BEFORE the coverage section?
