I have left the same message on the preview announcement, but I felt that it isn’t the right place for reporting bugs.
Enscape is not displaying an element that has been ‘unhide’.
You simply reproduce this by choosing ‘hide’ in SketchUp and ‘unhide’ afterwards, then Enscape does not show this whilst the viewport on SketchUp does.
? I can’t reproduce the bug - it works for me. (SU - Hide then un-hide an object/face/group)
what about a group?
oh, you said group is okay.
I will dig further.
I can reproduce this again.
@josephkim626 thanks for reporting, I can reproduce the problem.
Ah - I have a shortcut to view hidden geometry (H), then I un-hide again via the r-click menu - it may be to do with the menu item rather than “unhide” it’s self. (Until it’s fixed you can use this method)
Oh wow, I tried everything to remedy this issue. Your method indeed works!
I will stay with it until the fix. Strange how it behaves different to ‘unhide all’. The wonder of API and programming i suppose 
Thanks!
FYI Just tried to hide/unhide geometry by turning layers on/off and it has the same issue.
Fixed in 2.2.3.1625 preview version
