Скачать или смотреть Auto texturing Unity terrains with CityGen3D made much faster with multithreading.

Using CityGen3D it's possible to auto texture your terrains based on OpenStreetMap data.

Here's a preview showing how this is now much faster in the development build, with a 2km terrain made up of four 1km tiles each being updated in under 4 seconds.
In current release (v0.32) this takes well over 20 secs for each terrain.

CityGen3D performs millions of raycasts to identify how each half-metre portion of terrain should be textured based on the surface and user defined rules.

Code has been refactored to batch these raycasts and process the results across different processor cores using the new Unity jobs system with Burst compiler. So the next update should see these improvements in terrain texturing speed.

Further updates during the beta will implement similar performance upgrades in other modules, making large environments much easier to work with.

The scene in this video was created procedurally from OpenStreetMap data using CityGen3D in Unity.
