With InstantUV 1.1, textures atlases can be built with prescribed padding and minimum chart size.
The new version of the MOPS Command Line Interpreter makes this possible by providing new settings for the respective values. In cases where the prescribed values are not possible to keep due to large or badly shaped (elongated) charts, v1.1. of the instantUV C++ library allows you to automatically create as many atlases as needed. This way, you will get more control than before over the quality of the resulting textures.
