Stopping after creating chunks

[tholzmann]

Hello,

I have a problem with PotreeConverter and some specific laz files.

When I try to run PotreeConverter, it just stops after CREATING CHUNKS

I tried several minor changes in the laz file with the tool las2las, but nothing helped. I then also tried to run pdal translate without further parameters. This command then converted the file from las format 1.4 to las format 1.2. After this conversion it worked.

However, I really don't know if this was the reason, as we usually always use las format 1.4.

Does someone know what could be the reason for this and how I could debug it in a better way (PotreeConverter provides not a lot of debug output...)?

I'm using PotreeConverter 2.1.1.

Thanks! Thomas
