How to make trees and folliage interact with object (stop it from going through walls and roofs) & Black Meshes and foliages when using hdri backdrop

[Krissttiian1 (Krissttiian)]

How do you make so trees and foliages bend when it has contact with walls etc, or at least stopping it from going through walls and roofs ?

Edit #1:
And why my house and foliages are black when using hdri backdrop, I use real 1:1 scale in centimeter to model the house in blender, when i import it as fbx to ue5 it’s so much bigger than the default floor object in archviz blank template

You need to recode the material to use ‘mesh distance fields’. Just like they do for avoiding the player

There is no ‘tick box’ for this

Sorry to ask for more, but why my house and foliages are black when i use hdri backdrop and goodsky, but it’s fine when using sunsky

[ClockworkOcean]

I can’t recall, does Goodsky have a skylight?

[Krissttiian1 (Krissttiian)]

I guess not, so i need to add sunsky on top of good sky ?

[ClockworkOcean]

No, just put a skylight in the scene
