I am trying to import .obj files into Houdini and it seems it takes the numbers in the files names and adds additional characters in the filename. Seems it does this if something is named with a number.

Occasionally it will import the file, but most of the time if fails to load, with a file naming issue.

Just curious as to why Houdini displays the files this way and is there a setting to turn it off? Drives me crazy as I don't what the actual filename is when importing from a large directory of .OBJ files.

Try toggling off the “Show Sequences as one entry” toggle. This option attempts to collapse any file names with numbers down into generic sequences that can are indexed by frame number, hence the $F#.

myfile.01.bgeo > myfile.$F2.bgeo

something_5.bgeo > something_$F.bgeo

That fixed it!

Why I didn't at least try that checkmark I don't know. Never really noticed it there
