Can we export Geografted parts into Quixel Mixer as one obj?

LoreMistress Izaria

I am looking into exporting creatures like Cthluloid and G8 Centaur, etc to paint them. Does anyone know if it is possible? I have never used Quixel before, just downloaded it, and can't find any tutorials or posts covering geografts.

Would I combine the parts as one obj somehow? Would the UV maps still work after I combine them?

Any insight would be appreciated.
