Hello @jatoxa, thanks for posting! Can you share a simple reproduction package please. This could include your source data, a revit template file, an fmw workspace, and potentially the version of FME being used? Happy to help, Kailin.
Turns out I did miss a new setting as you have to select a view to get the proper appearances, so they’re still there. Not choosing a view will result in objects having a default appearance named “phase”-something, so I assume it's related to how Revit phases are read in FME.
