UV Map readability

[agi ridzky]

guys, i've a bit problem with UV here...

i made a mesh and unwrapped it in max and exported it to zbrush... but after i imported it in zbrush, it was like it couldn't read the UV map that was made in max.... Normal map and displacement map weren't active....

i solved this with using UV master... so i have new UV coordinate...

i wanna ask that could zbrush read uv map that previously made in max? or should the mesh is always unwrapped inside zbrush?
