Foliage Optimization in Unity [wayback-archive]
- requires your forest to be built from the ground up with your optimization strategy in mind
all assets share a single 2048x2048 texture
-
hex grid for grouping
- LOD and culling on the hex groups
- occlusion query against the hex groups to see if visisble (only check against terrain)
-
super hex grid encompassing multiple smaller hex groups,
- switch to combined model for all meshes when at the lowest LOD
