Substance Painter 2020.1 is here!

This new version comes with a ton of updates to make your life easier when texturing your assets: new Exporter, updated Bakers, new Python scripting API, improved Decal workflow, improved Automatic UV and brand new Mesh Export options!

Here are some of the highlights of this release. For the full details, head over to our blogpost.

[h3]New Exporter[/h3]
We rebuilt the export dialog from the ground up and you now have lots of new options to customize your exported textures with overrides per texture set or even per texture, as well as better feedback on what exactly is being exported.



[h3]Updated Bakers[/h3]
Bakes are at the core of the Substance Painter workflow, so these 2 updates should make creating stunning materials much easier:

The brand new Curvature baker delivers unparalleled quality, for what is arguably the most important mesh map to get Smart Materials to look just right. It's also RTX accelerated!



The Ambient Occlusion baker is also getting an update with better and smoother default settings and a new Ground Plane option.



[h3]Improved Decal Workflow[/h3]
A new shortcut (Alt) allows you to drag and drop a material from the shelf to your mesh and will automatically create a planar projection for you, allowing you to quickly add decals to your assets. The shelf is also getting a sample of XX decals from Substance Source's latest drop.



[h3]New Mesh Export Options[/h3]

• Tesselation and displacement export
  

When exporting a mesh, you will now be asked if you want to retain the tesselation and displacement, making it easy to export your asset to a 3D printing service for example or to a 3rd party renderer with just the right amount of details.

• FBX and N-Gons Export
  

You can now export in FBX format, and we will now retain your original topology (quads and n-gons) as well as the original hierarchy of the scene. OBJ export will also keep your original topology.

[h3]Automatic UVs Improvements[/h3]
New options are available when creating a project to allow you to force the Auto UV process, or to only run a part of it, if you only want the UVs to be repacked for example.

[h3]New Python API[/h3]
We are transitioning Substance Painter's API from Javascript to Python for more flexibility and better interop with other tools, and this release is the first step in that direction.
