Hi, is there any chance the input relative path is incorrect? The path was first look up to the drive ( in my case is D:/ ), after that just move into the specific hda file. That would impossibly to be used by other users via version control.

In my case, apparently the correct path should be ../../S1 Content/Houdini/s1__obj__curve__1_0.hdalc

Is there any chance to fix it up at incoming changing or modify it manually?

Houdini: 19.0.435
