Additionally, do TG shadows not even grow? At 25 meters, the shadows scale with the height and stay tight, instead of cascading. IRL shadows would cascade out at a distance, grow larger, and more blurry. Especially off-center shadows the lightsource.
Also, I have visible to other rays disabled on both the surface, and the shadow map, but can't get the shadow map to stop projecting on the surface card. May be the transparency. Also can't seem to get any displacement to show with transparency and reflections. Even if I use just the reflection layer with the displacement shader, there seems to be no wave definition, even with disp at 20.
