Command below works, log file looks correct, but nothing will be created with non root user under linux.

DensifyPointCloud \
--input-file $(pwd)/model.mvs \
--working-folder /path/to/images \
--output-file $(pwd)/model_dense.mvs \
--verbosity=3

So I check the Save code.

Is there a possibility, the save return false, but it be ignored?
