Hi there,

At the moment I'm modifying the code in a PythonScript Top from running “external” to “in process”.
I was presuming that using: would be the replacement for:
But apparently it isn't as it errors that __PDG_DIR__ is not defined.
The solution can't be difficult right?

…the benefits of using the (default) Evaluate In Process are:
- faster because PDG doesn't need to start separate sessions
- uses same Python environment as your Houdini session rather than a vanilla Python session

I'm using In Process whenever I can..
Just can't imagine the __PDG_DIR__ isn't available in an easy way.

__PDG_DIR__ is the TOP network's working directory, as specified on the scheduler for that node. Therefore, to resolve it you will need to call:

Thanks Brandon,

That will do.

I must say it takes quite some time to get grip on the different modes PDG can run in.
For instance this Python Script Top can run in Dynamic or Static and can run out-of-process and in-process.
Each with their different syntax when it comes to attributes, inputs, results and variables.

But I still like PDG a lot!

The good news is that H18 makes large improvements in this area.

Hi Chris,

Yes I had a sneak peak at H18 already.

In H17.5 I had just figured out I needed to add the following to my script:
(yes that can be more compact maybe and does only copy the first input file)

So I was happy to see I the new Copy Inputs To Outputs parameter in H18.
I don't have time to take a deeper look yet.
