It doesn't even give me the option for it.
But I need envelope/cage that I made in Maya (From the transfer maps menu) for baking in xnormal with my batch script.
I've checked manually in xnormal's viewport, it doesn't include the cage when I export the low poly, and it doesn't read the envelope mesh as a cage when I export the lowpoly mesh and envelope mesh together. I really need this step in my workflow to work, and there is no documentation for this on xnormal's site, or anything relevant to my problem that I could find on Maya.
What am I supposed to do? Am I using the right SBM plugin or something?
