LAZ file size

10 Gb LAZ?! How many points are there inside?

You can't go above 1 billion points I guess.

The maximum points in LAZ 1.0 - 1.3 is 2^32 - 1 (4.2+ billion). LAS/LAZ 1.4 supports 2^64 -1, but liblas that ClouldCompare uses doesn't support it. I can try to hook PDAL into CloudCompare if I get some time and that supports LAS 1.4.

If you're crashing on 1 billion points, you're probably having memory/arrangement issues within CloudCompare because it's not a LAS limitation.
