At GDC Unity showcased a lot of terrain features including hydraulic/thermal/wind erosion brushes as well as other improvements like different brush UI, distance normal maps being generated on the fly and so on. They were specifically called out as something already included in 2019.1 - but they are nowhere to be seen in the 2019.1 beta releases. I'm assuming they might be distributed in some repository or package, since simply holding them back for a later 2019.1 release would be a little strange now that it's no longer in an alpha stage. Am I missing an unlisted package somewhere, or are these tools and terrain system improvement absent from 2019.1 after all? Talk I'm referring to can be found on the first page of GDC Vault that went live today: https://www.gdcvault.com/browse/gdc-19#page-1 and is called "Hot New Terrain Features and the Road Ahead" (by Chad Foxglove). I'd appreciate any info on this!
