I'm processing terrestrial laser scans by converting E57 files to .las through CloudCompare then trimming and normalizing the .las files in R, but somewhere along the line I'm losing my intensity values. If I load a converted file back into CloudCompare, the values are still there, but after trimming and normalizing, plots with color dependent on intensity are uniform. I've tried using the breaks argument to increase color palette differentiation and filtering for intensity when I load the trimmed file back into R, but neither worked.
How can I check for where I'm losing intensity or how can I prevent this from happening?
