Polygon winding order flips on ever other triangle

[magnumpc]

Hi all!

I'm just getting up to speed on Irrlicht and am having a problem loading my simple box level that I exported from gtkRadiant. The 20kdm2.bsp loads fine, but when I load my hollowed out cube, the winding order of every other polygon is pointing the wrong way.

Is there some switch you need to specify during bsp compilation in gtkRadiant? I figure it's a data problem and not an Irrlicht problem because the demo map loads just fine.

I'm compiling with:
bsp_Q3Map2: (final) BSP -meta, -vis, -light -fast -filter -super 2 -bounce 8

I'm using Irrlicht 0.4.2.

When I do a test run, all of the textures are loaded correctly. It's just that every other triangle is flipped the wrong way.
