[fixed] Exporting models with holes doesn't work.

[Nova]

Exporting models with holes in 2.1.5 doesn't work at all. Every time I import these the holes will be filled back in. It seems as if the holes gets treated as hidden faces instead of actual holes.

I tried with .3ds, .obj and .dae and all exhibit the same problem. If I export with 2.1.5 holes are not exported. If I export with 2.0.4 everything works as expected. To reproduce:

1) Make Cube
2) Make any face a hole
3) Export
4) Import

For me, this is a huge problem as I use holes to lower the tri count of many of my models. With the holes not getting exported correctly, I simply can't use the models because of flickering, non uv'd faces as well as the increased tri count.

Nova, the cause is the same as the one for the other bug you reported.
I took a look on it and I found I introduced it by fixing a bug related to hidden faces.

So, late today I'm going to replace the wings_we.beam into the bug fix zip files since this crash seems to be more critical to the hole one.

The complete fix is out of my possibilities, so we need to wait for Dan to check it and don't get the hidden faces bug anymore.

Nova, please replace the wings_we.beam file I updated in the Some fixes to be applied to the current version: 2.1.5.

That should solve your problem, but will bring back the Hide bug reported by Hank.
