UV Master
Using UV Master
UV Master will generate UV coordinates for your ZBrush models in a single click.
When using a 2D map with a 3D model, the model must have UVs, which are 2D coordinates needed for your texture to display accurately on your model. UV Master creates the necessary UV seams,then unwraps and packs the UVs to make best use of the texture area. The result is an optimized UV map which is understandable to the human eye allowing work on the corresponding texture in a 2D painting software like Photoshop.
UV Master is powered by an unwrap algorithm which keeps texture distortions to a minimum. It can create new UV mapping automatically, with guidance for resolution scale and where seams should go. If you want to use other tools to extract data from your 3D models, ZBrush and its free Decimation Master plugin can reduce your high resolution model's millions of polygons by hundreds of thousands without any visual loss of quality. Further, when it is time to retopologize your model and create the low resolution base mesh you can turn to the powerful ZRemesher. A single button click is all that's necessary to retopologize most environmental models, while features exist to easily guide edge loops and polygon density where necessary for animated figures.
