Substance Painter 2018.1.2 is out with a number of improvements, fixes, and tweaks.
First of all, the update brings a significant improvement of the baking speed – the tool is now up to 5 times faster, and the team keeps working on future updates.
The save system has been rewritten becoming more transparent. It is now crash-free, and you can now choose between fast iterative saves (larger files), and slower (compact saves).
What is more, the new version lets users control the slider values with the keyboard arrows. You can also activate a “precision” mode pressing the Shift key.
To improve the padding situation, the new version lets users select which padding to use on a per-Texture Set basis: UV Space Neighbor padding or 3D Space Neighbor padding.
