I must say that GoZ is better than sliced bread, it makes moving data back and forth from Zbrush a breeze.
Had a chance to play with Zbrush 4 in combination with Modo 401 this weekend and wow i'm in love with it all.
The smoothness of the workflow this gives and the power of the combination of tools just blows my mind.

Not often that happens with a 3D application but this is really like being able to perform magic.
Sorry about all the big words but i feel they are necessary because it excites me so much! it makes me all giggly about 3d again hehe
Here's a quck test i did today, it was based around the basemesh 'Man Body 01' included in Modo 401.
I added a extra pair of arms, and a horsies backbody to the guy and then did a quick test of layered texturepainting in Zbrush,
one click of GoZ moved all my data including textures back to Modo.
