Here are a few screenshots of environment rendering in XLE. I don’t have a lot of art I can take screenshots of, so I can’t show a very polished scene… But you can see some of the rendering features.
Look for:
- shallow water surface animation
 - order independent blending for foliage
 - volumetric fog (& related effects)
 - dynamic imposters for distant trees
 - high res terrain geometry
 - terrain decoration spawn
 - “contact hardening” shadows
 - infinite terrain shadows
 
(see older screenshots here)
Here’s a shot of a turbulent ocean (though the indoor environment reflections are weird!). The ocean animation is dynamically calculated on the GPU, and can simulate both small waves on a calm ocean surface and turbulant large waves.
(some of the sky textures in these screenshots are from sIBL Archive)
