backround

I would like to have a backround of one colour (simple) but I would like this colour (of backround) would be lighter in a side and darker on the other side.
Like the backround of solidworks, for example.
How can I do that?
Thanks for your help.

You could probably draw a quad that covers the whole screen and just set the vertices to be the colors you want to blend to. Not sure if it’s the most efficient way, but it’s probably the simplest way.
