I just got modo and I was wondering if anyone has been using it with ZBrush. Are the compatible?
Since they give props to Zbrush in the Siggraph video…I reckon so!
Modo is designed to fit in with all major 3D pipelines which includes of course, the one and only ZBrush! Both applications are run by the very best innovative, creative development teams in the world and we the end user are blessed with these fine products. Both companies are continually working to improve and add new functionality to each application and the next few months should prove very interesting. …Just my humble opinion you understand. 
not until 201, which will be out later this year.
you can import your low and high meshes from zbrush into modo, but you wont be able to do much with them with the current version of modo.
YOu can export from modo as OBJ file an then inport to zbrush

The new modo looks impressive it looks like it got brushes to paint directly in 3d 
big video btw
I have been using ZBrush with modo. I use Zpheres to do a basic model, then import the model to modo to tidy up, make changes and add detail to the mesh; then bring it back into ZBrush for fine detail/sculpting and texturing. I find this to be a pretty good combination.
