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?

Hi, sorry for the late response. Yes, I only using laser scans for this particular object, And all of them have colors. However, we have limited light when scanning the interior of the house. My texturing settings is Fixed texel size, with texel size is 0.003

What kind of scanner are you using? What were you laser import settings? How do the created LSPs look?
Can you try to use Optimal texels size and not the custom value? Also, which texturing style have you used?
