Im not sure if this is a Maya problem or Zbrush problem, but i would guess Zbrush. Because, i have exported all my subtools from Zbrush into Maya, except one. When im trying to export the last subtool in Zbrush, there is absolutely no sign of it when i try to import it in Maya. I thought its strange, but im guessing its something wrong with it in Zbrush?
Could anyone please help me with this, if somebody have a clue?
