I decided to abandon trying to create PBR materials for TRS2019. When I imported my own NYCTA subway system that was created for TANE into TRS2019, the colors are not correct. Using Edit
Environment - Lighting window didn't help a bit. You have to click on each button around the clock and then edit the lighting. For the next version of TRS2019, when users import content that use legacy materials into TRS2019, the user should be asked if he/she wants lighting to be set for legacy materials instead of PBR materials.
