I have an issue with my foliage on UE 4.27.2, it just disappears from nowhere… which is very frustrating. I searched on Google already but i can’t find anything who works for me on google so i’m posting here in case someone knows.

I’m following a course so i’m still a beginner on Unreal maybe it’s something easily fixable ( i hope )
Thanks to everyone by advance.

If it can help some people, the problem was the instance count of the foliage who was too much important ( 1M3 in my case ), i managed to reduce it around 350k and seems to work fine for now.
