ZBrushCentral

Im having trouble getting going (but i am installed )

Ok so my problem is that i am just not quite getting it yet in the way of ZBRUSH controls.
I have been trying to keep up with the tutorials and such but its proving to be very difficult for me

so

i do have another program i use which has been mentioned here

RHINOCEROUS

Im learning very quickly with it however i want to take my files from there
and import them to ZBRUSH
but i just cant seem to get a file type saved that ZB will recognize

so here is my question

what filetypes or methods should i be using to import to ZB?

I do know that for example Rhino can save a file type of .OBJ
and i though this would be good enough for ZB to open

Any ideas?

ZBrush will import .obj files using the Tool / Import button.
