Graveyard - Unreal PCG Environment

This is my attempt at using Unreal PCG to create a graveyard. I used the storm setup from my previous project, along with the simple forest PCG setup I created by scattering grass, trees and bushes around a terrain. I also used Houdini to create vertex color masks for the grave stone assets. These were used to vertex paint moss onto the stones inside unreal

I used a spline to loop out an area and made sure that no trees or bushes spawn in within that spline loop. I sampled points within the loop that lie on the landscape. I created another spline to create a road and then filtered the points to get the ones that don't lie on the road. I used these points to spawn the gravestones.

I would like to make the vertex paint generator a bit more detailed and natural. I would also like to try and add more environment props onto and around the graves to make the scene look more realistic.
