Hello,

I've just started going over Jeffs' recent pyro webinar tut.

And as usual I try to look for ways to do equivalent expressions in python when I see an HScript expression being used.

Python in Houdini is my weak spot as I still have difficultly in utilizing the docs hou references in utilizing python in new ways.

In the tut Jeff is using the expression in a SOP Path parameter field of a gasresizefluiddynamic node.

Oddly enough when I switch the node preference to Python from Hscript, the expression still works as is.

But this is an exercise to learn a bit about Python.

It seems hou.parent() maybe with the combination of input() somehow could accomplish the same thing.

But after searching through docs and the net I haven't been able to figure this one out.

Help is appreciated - thanks

opinputpath(“../”, 0)

opinputpath(“.”, 0)

Thanks very much for this pezetko.

I like that you also give an example for the argument of “.”

This helps me go through the docs again as I saw reference to the equivalent of that also.

path() is a new one I didn't think/come across as well.

Thanks again.

opinputpath(“../”, 0)

hou.pwd().parent().inputs()[0].path()

opinputpath(“.”, 0)

hou.pwd().inputs()[0].path()

Hi,

I am not sure how to get similar result with path provided for example


I see the first option with ‘parent’ is relevant to my situation but I did not find how I should stick my path

I will be so glad for help, thank you

is this node

You can replace it with:

pezetko

pwd()

is this node

You can replace it with:

node('/obj/geo/Wood/dopimport2')

Thank you for replay

so the right code looks like this?


I tried different options but seems I do something wrong or I miss understand.

I would like to set soppath for ‘hero object’ which is in AutoDopNetwork Node and apply a correct path

Which node's inputs are you trying to get, ‘/obj/geo/Wood/dopimport2’ or ‘/obj/geo/Wood’?

Adding .parent() to the end will give you the parent's inputs, which in this case is the node called ‘Wood.’

Omit ‘parent()’ if you actually want the dopimport node's inputs.

I am trying to get ‘/obj/geo/Wood/dopimport2’ as input in soppath ‘rbd hero obj’ in AutoDopNetwork to achieve that result


The ‘Wood’ node is a ‘Subnetwork’ which contain other ‘dopimport’ nodes. I would like to specify that this need to be as soppath for my ‘rbd hero obj’

I still didn't find solution for my problem,

one more time

I have two nodes


(this hero object)

I would like to add this into soppath of my rbdobject which is and achieve the final results as .

Anyone know how to do it? I am stuck with this a bit

Thank you
