Why are the colors shown as black in Cesium? #52

Hello,

I'm calling with the following command, but the 8-bit part is returning false, even though my LAS file has RGB and intensity values. I converted my RGB values to 8-bit using Laspy. However, when I visualize my points in Cesium, they appear black.

What could be the cause of this issue?

Hello @kbratsy, the 8-bit flag needs to be manually selected as color depth is not detected automatically. Provided you are feeding a 8bit color LAS, try adding the --8-bit flag to your command and see if this fixes the issue. If this doesn't help, I'd need a small sample to troubleshoot the issue locally.
