(Updated) Image in UMG painted black after upgrading to 4.13.0

I am using UMG inside Pawn’s 3D widget to implement a crosshair in VR environment. (Just FYI this image’s color preset is set to white, doesn’t seem to do anything with the result though)

And, I attached this UMG into my pawn’s widget, to implement the 3D widget for VR view.

It works like a charm up to UE 4.12.5 but in the latest 4.13.0, the color just became black, with the alpha channel working somehow.

My assumption is, that this kind of 3D widget is receiving lights from 4.13.0, judging from the other UMG widgets with texts shining bright.
How can I make this work like prior versions? Is there any way to ignore lights for a specific widget?

Finally solved it myself.
I just rotated the widget 180 degree around Z-axis, then a magic happened – now it works just as I wanted!
I definitely checked again that the widget is rendered “two sided”, but it doesn’t seem to work in 3D widget yet.

Hope this helps those who are suffering from the same problem! :wink:
