[MCC Reach] Issue Previewing/Extracting .render_model LOD #12

Closed Unordinal closed 3 years ago

Unordinal commented 3 years ago

I'm having an ArgumentNullException when trying to preview or extract .render_models with a _lod# suffix from MCC Halo Reach maps.

These _lod models have vertices but they don't actually have any edges. I'm not sure how they are used by the game. The most recent Reclaimer update will now show a specific error message for models with no edges.
