problem multiple UV offset in Zbrush export


#1

I made a model with multuple UV map (0,0 for head / 0,1 for body) in Maya.

When I imported it to Zbrush for sculpting work, the UV retained fine.

But When I make it clone by UV master, The UV map combined as one map layout.
Also the size is shrinked by half.

Is there any way to retain multiple UV layout in Zbrush UV master?

Thank you in advance.
