By default Houdini prints messages to this floating Houdini Console:



However its content doesn't persist forever. When you print more lines, the oldest lines just disappear.

How could I output the console content to a file so I can have a proper log?

(on Windows)

One option is to use stream redirection from stdout to the file.
Or errors from stderr to file.

edit: here's also a way to just set an environment variable HOUDINI_ERRORLOG_FILENAME and the minimum error level HOUDINI_ERRORLOG_LEVEL.
