Striving for Photorealism in UE4

I will make a breakdown on a new scene soon Still figuring out new ways to approach creating the tree geometry!

The tree in that scene (duplicated about 30 times) has about 85K triangles, which is definitely a lot, but I have been experimenting more since then and can get a similar looking tree at about 35K tris. Keep in mind that I originally create these scenes for fun, without optimization in mind for games- since I get a lot of questions about performance, I’m working on creating a super optimized scene with a comparable amount of quality now. There were no LOD’s for the trees, and everything was dynamically lit- loads of room for improvement in performance! The trees in the background are simple SpeedTree billboards of the other tree model in the scene (that one has an extra LOD for super distant trees)- so they have very little cost!

The lighting setup is a dynamic skylight and a single directional light with a very low intensity- that’s it

Much appreciated and looking forward to it
