I have just made a copy of my 4.7 project and wanted to look at some of the new cool features of 4.8 when I noticed that my project somehow didn’t convert my foliage correctly
4.7
4.8
Seems like the setup of the LOD’s have changed, but I didnt activate the new Hierarchical LOD feature nor have I changed anything in the setup compared to the 4.7 project, but it looks much worse in 4.8. 
Have I done anything wrong? I hope someone can help me.
Thanks in advance
