Hey guys, how are you today?
Well, I’m using UE 4.24.3, my scene was exported from Sketchup using Datasmith and until here is everything ok!
The issue is when I build my foliage that I place in my wall (to make a Green Wall 
) and those artifacts comes up.
I’ve searched here, there and youtube but nothing solved this.
The weird thing is that only in the wall it appears. I have some others foliage on the floor but they are ok!
I’m using assets from “Temperate Vegetation: Fern Collection” that I downloaded form the marketplace.
Thanks a lot and sorry if I’m missing informations. This is it!
