I'm using a good deal of template code. Among that code is display00.wdl.

I have some environments/levels that have solid color backgrounds and different interiors/levels that I want to have no background at all. This is for reasons of optimization. Removing the background helps a bit on interiors. (Fellow noobs, you'll no it's gone if you adjust the sky_color settings and you create a window in your interior and see an odd motion blur-like render effect. (The trick is to have no windows/views of the backgroiund.)
In display change skycolor to all 0s.
sky_color.red = 0;
sky_color.green = 0;
sky_color.blue = 0;


The problem is that display settings of the first level get carried over to other levels.

Help is appreciated.
