When we give custom spacing and levels during PotreeConversion (example spacing 0.5 and levels 5) for different datasets and try to merge their results using mpc-merge, am encountering below error.
Error Stack Trace below:

This was because when merging two hrc files at line here the if condition never passes and it ends up writing empty hrc file of size 0 bytes. In the further merge steps above error would occur while merging the empty hrc file with another hrc file. Please let me know if you wanted a sample converted dataset for you to test the merge error above, I would be happy to provide one.
