All, For my scenery project I used the LIGHT_SPILL_CUSTOM light to create an omni directional light that easily can be adapted in color by using the RGB parameters. This works great however these lights are always ON, day and night. Is there a way to let these lights be switched together with all other lighting in X-plane? I know there is a dataref involved in this light parameter but I'm not sure if that is the way to control it. Anybody her knows how to do this? Thanks Lizz
