Choosing an application to communicate with
On the first click on a GoZ button, located in the Tool palette, ZBrush will search for supporting applications and when validating an application, ZBrush will install in the target application, the needed files. Please refer to the GoZ installation chapter for more information. Then, a window will ask you to choose between the detected application.
This application will be kept in memory by ZBrush and will be used each time you click on one of the GoZ buttons (GoZ, All and Visible).
If you need to change the selected application, please press the R button which will reinitialize GoZ. Click on one of the GoZ button to make the application selection box to choose a new application.
Note about Photoshop
GoZ supports Photoshop CC. The CC versions of Photoshop allow use of 3D models created in ZBrush, making it possible to paint directly on your texture rather than using PolyPaint.
Photoshop isn’t designed to support large polycount models. This means that you will always need to send low polygon models to Photoshop. You can of course use Decimation Master to reduce polygon counts if necessary. Try to avoid sending models with more than 20,000 to 50,000 polygons to Photoshop unless you have a powerful computer that includes a high end graphics card.
ZBrush will send only the low polygon model and the associated color map (located in the Tool >> Texture Map menu). This means that you must have UVs on your model and must have applied a texture to it before using GoZ to send it to Photoshop. A blank texture is fine.
Once the model is in Photoshop, paint on it however you like. You can use layers, blend modes, unwrap to paint directly on the flattened map and can even display the wireframe on the flat map. When your painting is done in Photoshop, send the texture back to ZBrush by clicking File >> Automate >> GoZPlugIn. Unlike the ZAppLink plugin for ZBrush, you don’t need to save your Photoshop file before performing this step. In fact, you don’t even have to flatten layers. (If you’ve turned on the wireframe view in Photoshop be sure to turn it off before returning to ZBrush or the wireframe will become a part of the texture as well.) Your texture will automatically be updated in ZBrush. Any PolyPaint beneath the texture will be unaffected.
