Trying to make some arenas for me and my friends. It's going pretty good. I've figured out a bit, however I can't seem to use certain things in dev tools. I wanted to add some darkness to a room but I can't move the slider when I place it. I also tried adding a fade pallette but can't use that slider either. Basically most sliders aren't working and I was wondering if this is a common issue, or a result from some mod I might be using.
