I've discovered a problem with the new version 3.0 of the DebugMode FrameServer in V16 but would like someone to confirm the issue.
In V15 (also V13 and V14), when opening the RenderAs dialog, there is an option to select "Render loop region only" under Render Options as shown here.
However, in V16, the Render Options button is grayed out as shown here.
Could someone please confirm the issue? Thanks.
