Hi !
I have faced very strange problem.

I have NAS in my network and everything works fine - i can write and read from any soft...but
I tried to import fbx from this NAS into houdini and it says that there is no such file. But file does exist..it's seen in choose file dialog

and i can export fbx from houdini to this NAS but houdini can not import this fbx back

the same happens with alembics

when i copy this fbx from NAS to local disk - houdini imports it without problems

What could be wrong with my NAS ?????

Hi,
Have you tried the latest daily build version? I meet the same problem with usd format in an older version.

I just tried it here and seems to work. Windows 10 21H1, Synology NAS, via File > Import > Filmbox FBX.

in this link there is the same problem and it can be solved by setting HOUDINI_ACCESS_METHOD

and it works....but

I have another problem - Xsense Animator can not export data to NAS

and the problem seems like happens to specific series of Synology DS

looks like there are some problems with NAS firmware

Ah right, I forgot that I have been testing HOUDINI_ACCESS_METHOD=3, which will be the new default in the next major release:

Changelog
Houdini 19.0.497: Tue Jan 11 08:26:05 EST 2022
For Windows, added experimental access method (HOUDINI_ACCESS_METHOD=3)
that uses the CreateFile() Windows API which hopefully gives better
behaviour for testing whether files/directories have read/write/execute
permissions, especially when dealing with network storage devices.
The default behaviour for HOUDINI_ACCESS_METHOD remains unchanged but one
may explicitly set HOUDINI_ACCESS_METHOD to 3 to test the new method.
