I picked a good month to pick up my Substance habit again!
Allegorithmic announced a bunch of new things, and showed some Unity love:

The Substance Painter live-link is a very nice QoL addition. The Substance library directly in Unity further helps my workflow - most of the architectural materials I’m looking for probably already exist.
Also, for you poor students: Free Substance tools.
