For new map I plan to use new terrain rendering asset.
It supports usage of 256 textures rendered in single pass with height map based blending. (Till now texture count was limited to 8)
That brings interesting possibilities for more realistic ground rendering with comparable performance.
And what is most exciting it supports tessellation too. That’s technique that I want to use for better cliffs, rock faces representation. Without using ton of 3D rock objects.
Tessellation is not an cheap technique and you need to have shader model 4.6 support on your GPU. But it can switch to fallback shader if needed.
Well video is worth a thousand words
