Missing geometry

[Skavengur]

I've got a problem with faces missing. I'm creating multiple models with 2000
or less polys. All the geometry gets exported successfully. (I've tested this
by creating a new movie and importing my model. All geometry is there.)

My actual movie(a space sim that dynamically loads all models using filename
meth) culls some faces - most of which are on an edge of the model. I also
sometimes have what look to hairline cracks between to faces at the edge. The
weird thing is....to clear this (mostly-not completely) I have to lower my
geometry setting on export. If I crank it up, the problem worsens. Also, it's
always the same faces, as long as the geometry setting is the same. I thought
I had this fixed (thanks to Hondo for the great tip about enabling
visibily=#both for testing), but it turns out it actually wasn't normals. I
just was seeing the back of another face that looked similar to what should
have benn there. I'm also using a simple, non-transparent shader. Although I
have tried multiple textures, the problem is always the same. I've tried
disabling LOD, and enabling it but at a bias of 100. Still occurs. It seems the
only thing I can do is adjust geometry on export, but it's not a complete fix
and I know there must be something wrong somewhere. I AM using
clonefromcastmember, and I've heard that can cause issues, but I'm not sure if
their related.

Please, if anyone has some thoughts, I would love to hear them. I've wrestled
with this for two months now, and I'm just about at my wits end. :-(

Thanks guys!

Ok....I just made a new discovery (for me anyways). If I scale up one subset of
polygons (I'm working with modular pieces) that subset gets the higher detail
with no or little geometry missing. However, the others then suffer from worse
quality.

Still dazed and confused.............
