Yeah the registered commands line is really suspect here, or what came before it. Most likely commands are being fetched from the server/config. Also I see they are being written to xml, which is how Houdini reads them. Check out tk-houdini/python/tk_houdini/ui_generation.py

Edit: from a cursory scan of the file, it seems not to change between context etc? This means the fix in the engine should be relatively simple - just do not regenerate the file every time if it exists.

Locate your houdini.env file (should be in C:\Users\pablo\Documents\houdini18.0) and make sure the PATH and HOUDINI_PATH contains the HTOA folders only once.

It should look like if you are using the HtoA installer:

After this, go to control panel / system / advanced system settings / environment variables and make sure PATH or HOUDINI_PATH does not contain any htoa specific folders there. (and logout/login if you do remove something from there)

I have gotten the same error. I have tried using the recommended version that City sample was created for and now even in 19 it fails at the same spot. Tracing the error it shows that it does not have access to read the BDF_Data.bgeo which is under the Freeway construction part of the Houdini script to cook. But it should have read access as i have my project set to that folder. I know City Sample had an update like 3 months ago, not sure if the code got changed.

Copy the content inside SMALL_CITY/houdini folder DIRECTLY INTO MyCity folder. For sanity I kept both the folder and the content inside this houdini folder in MyCity. I guess the content itself is enough.

Make sure your curve lines are not messing with your project, I disconnected one of the curves from the merge which connects to the arterial splines and I still had a warning sign displayed, then once I clicked process city base it started to work.

Yes, as I found - you need to copy all files and folders inside Small_City/houdini/ to your project folder. I could see the city shape after that but still get this error if my city shape is non-rectangular (if I make my curves extra smooth or change some properties like density).
