Hey ,
This seems to be related to an issue posted here:
Can you take a look and post your information there so we can track issue in one place? Thanks!
Using UE4.2 now and there is a bug with drag selection marquee not selecting everything inside of it, is this because some items are grouped/in a folder via outliner?
In addition to this, CTRL+RMB and Drag is causing rotation.
Hey ,
Just wanted to give you an update on this. It looks like issue has been resolved internally, and will likely be included in 4.4. There is not an official date for 4.4 yet, but we’ve been doing a roughly monthly update so we’re looking at about mid-August.
In meantime, please be aware that marquee select can be performed in Perspective view by holding Shift+Ctrl+Alt and LMB-dragging. Thank you for your patience while we investigated and fixed this bug!
