Pixologic UV Master
UV Master: UV Creation Has Never Been So Easy!When creating or using a texture map, a 3D model needs UVs. These are 2D coordinates that tell all 3D applications how to apply a texture to your model. Until now, the process of creating those UVs has been a time consuming challenge that requires a high level of technical expertise and has little room for creativity.UV Master is a free plugin which will create very efficient UVs for your models with a single click. Any artist can now quickly and easily create excellent UV maps. This free ZBrush plugin clearly represents the ZBrush ideal of maximum artistic freedom with minimal technical hurdles!With UV Master's cutting-edge technology you can leave all the technical work to the computer. Because the UV maps generated by the plugin can be in one UV island you will be able to understand your model's UVs in any 2D image editor and paint or edit them like you would do with manually unwrapped UVs. Amazingly, what needs mere minutes with UV Master could take hours in other dedicated solutions! Just load your model, click Unwrap and you're done!
If you need more control over this automatic process, use the Control Painting mode to restrict seams creation in specific areas of your model or paint areas which will attract seams. Just a few broad strokes will add more power to the process with minimal effort.In addition, UV Master's density mode lets you define areas where you need more or less pixel space for your texture -- without the need to locally scale or stretch your UVs by hand. For example you can give more density to the face and less on the back by simply painting the areas before clicking Unwrap!
UV Master Provides Several Utilities:
-Flatten and Unflatten the model's UVs for easy visualization. You can even tweak them with TransPose or the ZBrush sculpting brushes.
-Copy and Paste UVs between models of the same topology.
-Create UV islands based on Polygroups.
-Load a model with existing UVs and/or seams to unwrap it using the high quality UV Master algorithm!
-Use specialized Ambient Occlusion calculation to attract UV seams to the less visible parts of the model.
