Thanks Daniel, that explains everything!
I'm not bound to E57 for output so I guess I'll switch to PLY or BIN, that should work.

Hi All, I'm trying to export the Z coordinates to a new scalar field using the command line interface: CloudCompare.exe -AUTO_SAVE OFF -O C:\CloudCompareIO\test.e57 -COORD_TO_SF Z -C_EXPORT_FMT E57 -SAVE_CLOUDS FILE C:\CloudCompareIO\test+Z.e57 The script runs without any errors and the console ackn...

You could try remapping SF values to a smaller range:

Calc icon or Edit > Scalar Fields > Arithmetic:

SF 1: Intensity
operation: divided by
SF 2: [Constant Value]
put in a large number, ie. 1000 or 100000

You could try a workaround:

1. scale the pointcloud along the Z axis only: x(1.0) y(1.0) z(5.0)
2. apply subsampling (0.5)
3. scale the cloud back: x(1.0) y(1.0) z(0.2)

This should give you a point cloud with 5 times higher density in Z than in XY
