No time for going through tutorials, sorry. Apologies.
does the mouse cursor show for you once you clicked on the widget?
because i’m kinda having the same issue in 4.26 which i’m pretty sure didn’t exist in 4.25, my only workaround so far is to set “show mouse cursor” in the player controller to true and to use any cursor as default (if using none as default it wouldn’t work either)
and as soon as i click on the widget the fricking cursor shows up for me, so there might be some issue in 4.26 where going from 3D to 2D space with disabled cursor won’t activate the widgets cursor either. (as from my understanding widget cursor should show up even when “show mouse cursor” is disabled in the player controller)
