That back lighting was a total fluke. Was flicking through different materials to try and find "the visual", the thing that made it start to come to life. I came across the goop material in the Apocalypse Wasteland pack and, immediately was sold and began carving out a visual that captured my imagination.
The water reflection bit was a last minute change. So the water surface is 'SM_Env'OceanPlane' in the Dark Fantasy pack. The largest green on the water is from the directional light (Moon) in my case, and that night shimmer ( wish there was more), is from the 'SM_FX_Electricity' asset in the Dungeons pack. It was close enough to the water to get picked up which was just great cause I wasn't liking the lack of detail in the water.
Appreciate you, thanks for the comment and question!! :)
