LiDAR texture doesn't appear at all surface

Hi there,
I am a first-time user working with LiDAR data for texturing geometry. I fully understand that LiDAR data might not produce the best results for texturing. However, I’m curious why some surfaces have color while others do not.
Could someone provide tips or suggestions on how to improve this result?
Thank you in advance!

Hello @yanayuliana
Are you using only laser scans in your project? Do all of them have colors? What are your texturing settings?
