3dsmax 2012 I can't upload any mirrored meshes!

[BlackHeaven1983]

I'm using 3dsmax 2012, I export my meshes as fbx, then use the autodesk fbx converter to make them into dae files.  I've noticed that if I mirror my mesh in 3dsmax and export/convert/upload it to SL, I get the error "missing level of detail".  Yet I can make clones of my object and they work just fine.

 

Has anyone else experienced this issue or might know what's causing it?  ..Is there more than one way to mirror an object in 3dsmax?  

 

Thanks in Advance!

Ok....apparently when you create a mirrored object it trianulates some of the polygons which SL doesn't like.  So you have to use a "Symmetry Modifier" to mirror the mesh.

Either that or reset XForm after mirroring.

The problem is the mirrored geometry has some odd values: negative volume and an incorrect center off mass, even in 3ds max itself. (Utilities -> Reset XForm).

 

Alternatively you could attach the mirrored mesh to the nonmirrored mesh. (so the attach button with the original selected).
