I have a CSV that is generated through Unreal Engine, and Houdini generates points based on the information.

I cannot further edit this once it has been loaded into Houdini or a HDA in UE because it is being used still by a Houdini process.
Are there any methods to break this lock on the file inside H, I can't think of anything at the moment, and creating a copy will just retain ownership of anything referenced in a node.

does it still happen if you close the csv file when you're done reading it, or use a "with" block in python when opening the file?

How would you close the CSV file - I don't know of a way to do that. It does run partially through Python and a C++ file generates a file dependent on the points in UE, but I know the HDA is 'locking' the file as I've checked in windows and it's being possessed by a Houdini process.

I added a toggle switch linked to the table import exposed in UE and it seems to work, but needs to switched manually everytime.

The author of 'table import' needs to fix the code to close the file.

Edit:

I guess that's a sidefx node. Submit a bug.
