Substance Painter 2018.1 introduces a brand new interface with a lot of improved behaviors. Performances have been improved as well in a lot of areas.

Release date : 15 March 2018

Major Features

New interface and behaviors

Substance Painter 2018.1 introduces a complete rework of the interface, ranging from color and icons to widget behaviors. 

  • The new interface focus on bringing a brand new design, making it easier to read and less cumbersome to navigate.
    We reworked all our icons to be more explicit. We also reworked our color scheme which should now be more consistent.


  • We improved many widgets, especially our sliders, to be more easy to use with a Tablet Pen.
    You can click on the bar to move the slider or use the value field to more precisely edit the numbers. 
     

  • We have a new toolbar that allows to open Docks on the fly. 
    Clicking on one of the buttons in the toolbar will display the Dock next to its button and floating above the rest of the interface, re-clicking on the button will close it.
    If the dock move away from its button, it becomes a regular floating window which can be docked in the interface. If closed, the button will be available again in the Dock Toolbar.
    This new dock system works more easily with fullscreen. There is no need to have every dock always present in the interface anymore. 


  • Docks now use our new Tab layout which organise items into sections while still being able quickly scroll inside it. 
    This Tab layout allows big windows and can present all the information at the same time, contrary to regular Tab systems that hide information.
      

  • There is now a Quick Menu, which makes Tool properties available directly in the viewport.
    To open the quick menu, simply right-click in the viewport. To close the quick menu, click again in the viewport.
    The menu will only close when clicking into the viewport, allowing the drag and dropping of resources from the shelf directly into the quick menu.


  • There is now a new Contextual Toolbar at the top for the viewport.
    This toolbar change its parameters depending of the current tool used. It's a way to quickly access basic tool features (like the brush size).


  • It is now possible to reorder effects using drag and drop in the layer stack


  • While the shortcuts "C" and "B" allow you to quickly vizualise the Channel and Baked textures into the viewport, it is now possible to use the unified dropdown to change the viewport display.
    At the top right of the viewport there is now a dropdown listing all the Channels and Mesh maps (previously Additional maps). This unified dropdown is also available in the Display Settings dock. 


  • The Display Settings and Viewer Settings have been merged into a single Dock.
    Environment, Camera and Viewport settings are now grouped together, while Shaders parameters have been moved into a dedicated Dock instead.
    The Display Settings now takes advantage of the new Tab layout to quickly navigate the window. 

Drag and drop of Materials and Smart-Materials into the Viewport

You can now drag and drop Materials and Smart Materials directly into the viewport
This new action will highlight the geometry of the of the target Texture Set at the same time. This action will create the new layers at the top of the layer stack of the Texture Set.

Improved tablet pen behavior

In this version we improved the way we handle Graphics tablet pen movements and inputs, especially when Substance Painter is under a heavy load.
We no longer lose the inputs anymore while we are doing consecutive computations. This should allow precise brush strokes in any situations.

Improved seam padding

We reworked the way we generate our padding outside the UV islands. Instead of taking the current pixel and dilating it on a certain distance we now look for the neighboring pixel on the other side of the UV seam and interpolate the two values.
This gives a much better end result and reduce the visibility of the split between UV islands even when the textel ratios don't match.

 

This new padding is automatically generated after each brush stroke, resolution change or layer modification.

Improved performances

We also improved performances in this version on multiple levels :

  • Opening and saving project should be a bit quicker than before.
    We reworked the way we encode/decode our painting data. This especially affect projects with a lot of paint information (brush strokes).

  • We now support lot of sub-objects with meshes.
    It isn't mandatory anymore to merge a mesh into one piece before loading it in Substance Painter. Performance should stay good even with 8000 sub-objects in a project.

  • We changed the way our viewport is refreshed to reduce the load on the GPU when painting.
    This means we no longer update the whole image but instead a small region where you are currenlty working.
    You can feel the difference on less powerful GPUs or when using a high sample count in your shader.

  • The shelf system is now faster to discover resources when launching the application.
    Substance materials with embeded bitmaps are twice as fast to discover (if cooked as non-solid). Presets should also see improvements.

Global scene position baker

We now have a new setting that allows to bake a position map per Texture Set that take into account the full scene size. 
This new behavior allows to use triplanar projections in Mask Generators that will match across the whole scene instead of creating seams like before. This is really usefull with projects that have a lot of Texture Sets (like UDIM based projects).

In the position baker settings, change the the parameter "Normalization Scale" from "Per Material" to "Full Scene" to enable this new behavior.

New content

We also added some new content in this release :

  • New 3D noises.
    Imported direclty from Substance Designer, 4 new 3D and totally seamless noises have been added to the default shelf.
    These new noises rely on the posiiton map of the project to generate a result without any seams.

  • Non-square noises
    The base noises have been updated to the latest version from Substance Designer.
    This means that the non-square expansion feature is now available in the noise parameters.

    The 2D view still display non-square resolution as square at the moment.

  • New mask generator 3D Linear Gradient.
    This new mask generator allows you to create a linear gradient in any direction in 3D space.
    The direction can be defined with two 3D positions, which can be picked on the position map directly.
    Example : 
    1. Create the mask generator 3D Linear gradient in one of your layer
    2. Switch the viewport display to "Position" (via the viewport dropdown or by using the "B" key)
    3. Click on the "3D Position Start"  parameter to open the Color Picker pop-up
    4. Pick a color on your mesh in the viewport
    5. Repeat the process for the second parameter "3D Position End

  • New template Lens-studio (Snap Chat 3D app).
    We have a new template to easily create projects that target the Lens-Studio application created by Snap.
    A dedicated shader and export preset are also available. For more details about Lens Studio see : https://lensstudio.snapchat.com/

  • Smart Materials and Smart Masks have been updated with the latest version of our Mask Generators.
    Our Smart presets now all support the micro details feature which can be used with Anchor points.

New sample project

There is now a new sample project named "TilingMaterial" that you can open via the "File > Open Sample" menu action.
This project use a simple plane mesh with overlapping UVs which allows to paint seamlessly materials and brush strokes to create tiling materials.
