I'm using some of the default shapes provided that are idea for my purposes. Now that you're mentioning the check boxes in the properties I THINK I know what I forgot to do. I'll play with it more in the morning.
I HAVE run into another irritating problem...
I've created (well, modified from a stock model) a new object for my map. It displays perfectly fine in AC3D. HOWEVER, when I bring it into the OE, the "preview" in the corner is missing a VERY visible (and quite important) part of the model. When I add it to the work area, however, it's fine. But again, when I actually add the object to the map itself, it's back to missing those poly's.
I've had this happen once before, and I fixed it by rebuilding the entire model. The thing is, all I did was remake them the same way I did originally and the second time it worked. I HAVE tried flipping the normals, tho not vertex order as of yet (too late, and tired of messing with it). I'm not too familiar with AC3D (used to Rhino) and I THINK it's because I'm really looking at back faces, but I can't find an option to turn view back faces off. Anyone got a clue what's up with this?
