Hi,
would be great if you could add a possibility to set sky_color to total black.
It´s always bugging me that when additively blending light volume geometry I lose some precision due the non-zero background color values.

Thanks

This indeed would be a nice addition. The ability to completely turn off the background color should be implemented in a separate fashion. For example, why don't you just let the user wipe the screen himself, or create a new engine variable that controls this?

Black switches off the sky color, but a simple workaround is a 32 bit black sky cube or sky cylinder.

But the native skycubes are rendered last and therefore don´t help me with my additive blending problem.
