3DS to Maya Layers
Previously, 3DS Python Script to JSON external file but 3DS revised their API (i.e. removed the MaxPlus library). So workflow is:
- exporting FBX.
- importing FBX to Maya. The layers info are retained.
- importing FBX to C4D. The layers info are NOT retained.
- Rebuild the Layers Info to a Grouping in the Outliner.
