I don’t think it’s possible, but I’m using the new LAM from the marketplace and it’s beautiful! It brought my scene to life in a way I could not, and it’s seriously flawed. Rocks are added using Grass Layers which means they have no collision. Any way around this without removing them?
I don’t think Epic will add that ability to Grass Layers because it may be too expensive, but it would be awesome because the results you can get from them are amazing!
