Merge polygroups to one zbrush

Since ZBrush supports bit depths, you will get a true bit alpha. It allows you to add details from the alpha to your sculpt without destroying details already on the surface. Note: Alphas are displayed as thumbnail images in the alpha pop-up palette, but are always saved with the full dimensions of the source image from which they were created.
