A modo kit by @csprance to convert an OSN to a TSN directly inside of modo using xNormal.
xNormal must be installed on the users system in order to convert between the two different maps.
Installation
This is a modo kit so install it like normal. I've only tested this on Modo 12, but I don't think it's doing anything fancy. Let me know if you run into any issues and if it works on other versions of modo!
Extract/Clone into %appdata%/Luxology/Kits
Restart modo
How to use
Select low poly meshes to use
Right Click on the Object Space normal texture in the clips browser in modo and select "Convert OSN -> TSN"
On first run you will need to set your xNormal path from the dialog that opens up
Texture will be converted and imported into the clip browser
Uninstallation process
Delete cs_osn_to_tsn from %appdata%/Luxology/Kits
