Reflectance calibration does not produce the results shown in the tutorial

Hello,
I am trying the tutorial for ALTUM spectral camera's reflectance calibration.
https://agisoft.freshdesk.com/support/solutions/articles/31000148780-micasense-rededge-mx-processing-workflow-including-reflectance-calibration-in-agisoft-metashape-pro
I got reflectance values CSV from micasense and loaded it into Metashape.
In the tutorial, generated dense point cloud and orthomosaic is RGB colored,
But when I tried same procedure in the tutorial, always I get "Black" orthomosaic and pointcloud.
Do you know to solve this phenomenon?
Best Regards,

Hello t.h,
If you need to get the good-looking RGB output, then you can adjust the coefficient in the formulas and then use Index Color option in the Raster Transform section of the Export Orthomosaic dialog.
