Lidar not hitting Unity Terrain #145

Description

Hey all, I've created some custom offroad terrain using the Unity Terrain editor, but unfortunately the lidar does not register hits on the terrain. My terrain has a Terrain Collider, but I guess that doesn't seem to work - can anyone suggest a smart workaround for this problem?

Just a small update, I currently worked around the issue by exporting my terrain as a mesh to a .obj file, and then reimporting it, overlaying it with the terrain and assigning it an invisible material. It works for now but I really don't like it ^^

Good news! We are currently working to support terrain by LiDARs (by RGLUnityPlugin). I am sharing some early results. The feature will be merged into the main branch soon.

That is hardly a remedy, I did the same temporarily, but what about other objects, e.g trees or plants ? Great news that they are working toward it.

Good news, terrain is now supported as our pr has been merged. RGL supports now terrain heightmap and trees, but not detail objects, such as grass.
