i was playing around with shaders, as the font material shader uses az older (i’m guessing IMGUI) shader which doesn’t zwrite and/or ztest and so looks bad on worldspace ui-s, and i copy-pasted a custom uitext shader from the builtin shaders, and somehow it started working (you can change text colors, tested in b18/b20), altough i dunno why, as it is the same as the UI-Default/UI-DefaultFont shaders.

i’m also including the .mat file, as the parameters it contains from other shaders before i set this one may be of relevance to the devs.
