Hello, I recently had this issue where I was building my route and all of s sudden, the trees leaves disappeared leaving nothing but the leaves. The shadows are still cast as if there was leaves. Also when I zoom out a bit, the leaves start showing again but when i zoom in decently close, they vanish leaving just the trunk and making it look hideous. I have this issue on all my trees on very route I have and I am mostly using speedtrees but some other trees are also affected. Can anybody please help me fix this issues?
