This tutorial will show some steps on how to optimize an outdoor level to get better performance.

The terrain is the main part of an outdoor level. It should make out most of the geometry of the level.

Rendering terrain is much faster than rendering multiple meshes. To get good performance it is important to use the terrain to make up most of the silhouette of the level and just use meshes for important landmarks and details.

To be able to use terrain for all of the silhouette it is possible to set a Cliff Texture (soon in the editor). With Cliff Textures it is possible to use terrain as walls instead of having to use meshes. The cliff texture is automatically projected to the steep cliffs of the terrain.

Terrain optimization checklist:

• Unit Size should be 1 or higher
• Geometry Patch Size should be the same size as Texture Patch Size
• Undergrowth Fade End should be 40 or lower
• Don't use too many different undergrowth materials (1x draw calls per material type)
• Use Cliff Texture for walls
