3DS Max Mirrored Objects Broken In Unity

LittleBigAlex

Whenever I mirror any objects in 3DS max and import them as FBX files into unity they appear flipped. Is there something I need to do inside 3ds max to stop this from happening. 
Is this related to the objects pivot when it's mirrored in 3ds max?

In 3ds Max, reset xForm and convert to poly after mirroring the object.

Okay, thanks.

After resetting the XForm, you must go to the Modify tab, click Element, select all and click on the Flip button.

To add to what Ausonian said, before you reset the XForm enable Backface Culling in the Object Properties. This way you'll be able to spot inverted normals before export.

Better yet, never use the Mirror button on the Toolbar. Only use a modifier to mirror your meshes.

The Mirror button uses a negative scale to do its dirty work. Most exporters do not support this.
