Hi, first of all sorry for my bad inglish ! :slight_smile:

I have created a little games (KawaiSlender). Everythings is working in editor but when i export my project and i running my games on my computer some texture disappears. I thinks its cause by the foliage editor because its just the object placed with this who don’t work. I don’t now how to fix that i’m a beginners. Thanks for your answers.
