Technically, there are bundles, you just need to add them.
How to add them?
First, open the Novetus SDK and go to the Item SDK.
Second, create the item by giving it a name and changing the type to Package.
Third, go to the Mesh Converter. If your body parts are already in .mesh format, you can skip this step. Otherwise, convert your body part files (it only supports .obj files).
After that, go back to the Item SDK window, open the Item Settings panel, and browse for those body parts.
Finally, save your item. You will be redirected to the Player Customization window. From there, go to the Extras tab, and you’ll find your package there.
Have fun with your ARG!
