Substance Painter's largest release to date this year is now available!
This is the last major release for owners of the 2019 version.

This new version of Substance Painter is getting game-changing updates on many fronts:

• An improved Painting Engine, featuring Photoshop Brushes (ABR) support, improved tablet pressure handling and tons of new brush parameters to make your painting more enjoyable.
  
  
• A brand new Automatic UV Unwrap feature, allowing you to import any model in Substance Painter and get a high quality UV unwrap, even if it had no or terrible UVs in the first place!
  
  
• The Roll Brush, a new tool for which the content of the briush bends and curves with your strokes, extremely useful for adding organic as well as hard surface details!

Last but not least, full support for UDIMs is upon us, and a closed beta will start next month, fill out this form to register[www.substance3d.com], but hurry up! The beta will be limited to 500 users at first.
