Hello! I am trying to generate foliage on walls using the given procedural generation tools. It worked fine on the ground and now I’ve tweaked the details following a tutorial that I found on UE4 AnswerHub but it doesn’t seem to work. Here’s what I did:
I’ve created this foliage generator to which I’ve assigned my tweaked foliage actors that I’ve imported from Quixel Megascans. Here’s how one of them looks:
As you can see I’ve set it to be “Aligned to normal” and assigned 180 as the maximum align angle and ground slope angle. This is how I place my generator on the walls:
I have changed it’s rotation to 90 degrees (I don’t know if that is needed however). Clicking “Resimulate” gives me this error:
Keeping the rotation at 0 or -90 gives the same results. What am I missing here? Thanks in advance!
EDIT: I’ve set the values to 180 because later I’ll want it to generate on the ceiling as well.
