Raylib overlay background not transparent #2

Hi. When I call any of the raylib blueprint functions (draw text, shape, texture etc) the screen is filled with black.

Looks like the ClearBackground(BLANK) in RaylibUE_Render.cpp call is meant to make it transparent but is not working. Does not look like ClearBackground (or maybe the overlay render) supports alpha values at all. I tried with different color values in ClearBackground but alpha did not any difference.

I am using UE 5.6.1 with RaylibUE compiled from source (the release binary throws an error when I try to build).
