## Optional

### LOD Name Suffix

Parameter ID: `FBXEXPORT_LOD_SUFFIX`

If this option is enabled, the objects under the LOD object will be given the suffix **_LODx**, whereby the x represents a consecutive number. Unity 3D, for example, requires this naming convention.

Note that FBX only supports the **LOD Mode** Children, whereby **H/V Screen Size** and **Screen Surface** is output as a percent value, which can, for example, be read by Maya.
