I’ve created an environment with Houdini and imported the heightmaps in to Unreal to create an UE environment. I’ve filled a PCG volume with foliage and they appear for the first 30 frames of the animation and then they disappear. This happens with path tracing and lumen. Creating a new level without importing the heightmap renders without issue.
I have done lots of trouble shooting but yet to find an answer. Has anyone had this issue before?
Thanks!
