When creating a new blueprint using either the Toolbar|Blueprints|New Class Blue Print menu or the Content Browser | Create Browser | new Blueprint menu. The “Pick parent class” dialog boxes aren’t being populated and there are two of them! I get this on Unreal 4.6 built from the gir repo on a linux machine.
Seeing this bug on the master as well
Is there some module I should be building and I’m not?
OK
So I can add a bit of trace to the SClassPickerDialog::Construct() call and I see
Pick class
new asset default clss Actor ClassIdx
adding new asset default clss 0
new asset default clss Pawn ClassIdx
adding new asset default clss 1
new asset default clss Character ClassIdx
adding new asset default clss 2
new asset default clss PlayerController ClassIdx
adding new asset default clss 3
new asset default clss Game Mode ClassIdx
adding new asset default clss 4
Add modal window
So it looks to me like the picker dialog is getting the correct list of things to populate the dialog but the problem has something to do with the dialog itself
I suspect that the second dialog is just the Pick Parent Class being drawn then moved to a new position and redrawn. When modal dialogs are being displayed it’s not redrawing the background window (it’s like working on windows :).
I might also add that I can open the level blueprint fine.
This is fixed in the current master branch, a.k.a 4.7
