Hi, We also need to change the intensity of LiDAR scan.
You mentioned, "You can try adjusting the reflective intensity of the material to see if you can get the desired result", Which properties should I change? I did not find any properties about "reflective" in material settings. Or any update for chrono codes? Thanks.
