The beta branch has been updated with the following changes:
- Added preliminary shader support for PBR materials and parallax corrected cubemaps. No map compiler support for the latter yet.
- Updated Source Engine libraries to the versions added to Alien Swarm in August 2020 (other than the two that were already updated then).
- Added a preliminary version of the Reduction campaign.
- Yet another attempt to get dedicated servers to update workshop addons to the latest version.
- Misc. code cleanup. (Thanks kablooey123!)
