Importing a Sitescape point cloud PLY file to use to build environment in Unreal Engine.

[SupportiveEntity]

Hey there @Jack_El_Camino! Welcome to the community! PLY files aren’t natively supported by the engine, it’s recommended to convert them to another supported format depending on your needs.

If you want the scan to be a solid mesh, I would recommend converting it to OBJ or FBX in another software for easy import and handling in engine. This thread goes over the two ideas of either converting to OBJ or FBX or swapping to a Lidar point cloud plugin compatible format.

How do I import and visualize ply files in Unreal?

Hello, It seems ply can store vertices and also triangles not unlike OBJ format. You can modify the header and only preserve the vertex data, then format it as a XYZ, and finally use the Lidar plugin in UE to read those data LiDAR Point Cloud Plugin Overview in Unreal Engine | Unreal Engine 5.1 Documentation If your ply has triangle data and you want to preserve that you will have to convert it to OBJ or FBX using script you can find on the internet or free tool such as blender.

If you want the scan as a point cloud, E57 format would be ideal but there are some others available via the Lidar Point Cloud Plugin:
