Roughness is zero

[bigbang21]

Hello,

I am using CC ver.2.10.2. I tried to get roughness value of two dense point cloud models.
One model shows a specific range of roughness with scale bar.
However, another model shows only blue color and roughness shows zero...
Any advice??

Thank you.

This is not super clear: do you use the same radius to compute the roughness on both clouds? And do the clouds have the same density (more or less)?

Also mind that the colors are dynamically mapped between the minimum and maximum (roughness) values, therefore they might not have the same meaning on both clouds (you have to defined your own 'absolute' color scale to get the same color for the same value on both clouds).
