My foliage will not cull since 4.15.0
Foliage isnt culling anymore. My foliage tries to render for miles even though it is set to 10000 units max. This drives my editor to useless mode. 4-15 FPS.... All i did was update to the new engine... The bushes are set to cull at like 3000 units which worked fine in 4.14.3, now those bushes you can see a long ways off....
First Screen Shot shows low FPS Second Screen shot Shows Shader Complexity showing Foliage not culling Third Screenshot Shows Foliage Setup
Video shows severe Stutter when and poor FPS when foliage is in the viewport This was not a problem in 4.14.3 i would get between 80-120 FPS at all times. https://www.youtube.com/watch?v=aEyKTACW_Ko
This happens because your foliage material(s) do not have the "Dithered LOD Transition" checkbox checked. Without it in 4.15 instances will not fade out. Previously if this checkbox wasn't checked, dithered LOD transitions would occur but would render an ugly black artifact as well.
The flag is under the "Material" category in the advanced properties rollout.
Note that this flag must be set on all materials used on all LODs of your foliage mesh for the dithering and fading to work correctly.
I opened the content you linked above and confirmed that fixes the issue.
