Substance Painter 2020.2 (6.2.0) is now available and features some of the most requested features to date! For the full details, read our blogpost on the Substance Magazine.

With UV Tiles, you can now load complex UDIM models and use all the tools painter has to offer seamlessly across UV tiles boundaries. This means you can apply filters, generators, smart materials, paint and even throw particles across multiple UDIMs.



To supplement UV tiles and make sure everything runs smoothly, we added a new UV Tile mask, allowing you to quickly mask UV Tiles to apply effects or materials only on some parts of your object.
While painting on a layer with a UV Tile mask, you can now hide all masked tiles, allowing you to focus on the area you want to paint while hiding the parts that are in the way.

To support those heavy UDIM projects, we had to go back to the drawing board and optimize every step of the workflow:

• Project files (.spp) are on average 20 to 30% smaller than before.
  
• Saving and auto-saving is 20% to 50% faster depending on the project
  
• Exporting textures is now up to 10x times faster as well!

A new Pause button allows you to temporarily pause the Substance painter engine, letting you chain multiple costly actions like applying several smart materials on a complex project without triggering calculations until you un-pause the engine.

You can now choose specifically which Texture Set and UV Tile to bake in the baking dialog.

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.

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.



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.



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.

• 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.

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.

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.
