Vred2019 Pro - what happen to python execfile ?!

Bob.Bon2000 — Fri, 20 Apr 2018 14:46:44 GMT

What is the new replacement for :

s.send("/python?value=execfile('C://test//x.py)'".encode())

All I get is

Couldn't execute command 'execfile('C://test//...'!

Thanks.

Hi,

in 2019 we made some changes regarding the security of some Python calls. However, you can revert it by starting VRED with the command line option "-insecure_python". Hope that helps.

Cheers,

Marcus

Hmm I had a feeling this is going to happen.

Will this functionality remain or it will be removed within next 10 releases?

There will never be a solution that fits for all. But if an IT department of a company with hundreds of licenses sees this as a security issue and showstopper to roll out ... we do these adjustments. Sorry if it broke something else.

Hey

yeah I agree, it was quite a security issue, but at the same time in closed networks, it did not matter and allowed us to build up quite a few systems on it.

In this case, how can we tell vred to execute a script after he finish his startup procedure?

TIA

Hi,

as I wrote, your code will work like in previous versions if you start VREDPro with the command line option

"-insecure_python". You can add it e.g. to the desktop shortcut by right-click on the shortcut -> Properties, there you need to add it to the "Target" which should end up in something like this: "C:\Program Files\Autodesk\VREDPro-11.0\bin\WIN64\VREDPro.exe" -insecure_python.

Another solution would be to use another command line option called "-postpython", which will execute after VRED has launched or loaded a scene (see command line option description: VREDPro.exe --help).

Cheers,

Marcus

Humh... bit tricky. Is there no folder in vred like plugins/autostart or something like that where we could place .py files and let vred auto execute them on start?

No, there is no autostart folder.
