i'm having some troubles finding the way to play with a black background on Android/OpenGL ES 3 GKGL.

is it still an option?

/set rHiRezBK 0

YAY ME!

You can also hide the space junk:

/set rDoSpaceJunk "0"

Or you can use the Background Toggler plugin to do both:

yeah,
i can do it by typing some console command or by editing my wgaf.conf file or by installing that Rin's plugin...
what i CAN'T do is set it from the "Graphic Options" panel of my VO client...
Funny thing is i got it reversed as soon as i confirm the changing of any other value in that panel.

Prolly this belongs to the Bugs section.

DUH!
