Lets look at just one face for now:
Code: Select all
vertex -18 -47 0
vertex -18 -47 26.5
vertex -18 -51 0
vertex -18 -51 26.5
face
vertices 4 5 6 7
drivethrough
shootthrough
matref wall
endface
You have to imagine the square in your mind...you start at one corner, and move along each edge.
The way you have it, the face starts at vertex #4, -18 -47 0.
Next, it moves to vertex #5, which is directly above vertex #4.
The problem arises with the next vertex. It is diagonally across from #5. This means the program will try to connect #5 and #6. This would be fine if you wanted a triangle, but when you are making a square, the points have to be in order.
So: if you switch vertices #6 and #7, it should work.
