Exporting 3D models from 3ds Max for use in UnrealEd

Preparing your mesh
Ensure that the model is a single object, and is of type Editable Mesh. You may wish to apply a Smooth modifier, so that the exported model will preserve its smoothing groups when imported in UnrealEd.

3rd person weapon tags
If your mesh is for a 3rd person weapon model, you will want to add tags as appropriate. The tags are: Create your tag as a new Dummy helper, and name it one of the names above. Place it relative to your model where it needs to go. Then link it to the model. (Image: 3rd person weapon tags linked to an MP7A1 mesh)
 * TagScope
 * TagMuzzle
 * TagGadget
 * TagMagazine
 * TagCase
