Python SOP and L-system

[kursad]

Hi

I am trying to generate rules for Lsystems via Python SOP. I created my script, it works fine as a standalone app , it does create what I want. Now I want to integrate into L-System Sop. I figure that I can create a Python SOP and write over the Lsystem rules channel. But I am slowly getting into Python for Houdini. Could someone give me a basic lead on this one?

I know I can create a rules text file via Python and let Lsystem to read it, which is a solution but at this point I want some automation

thanks

Any suggestions on how to change parameters upstream via Python SOP?

I am trying to achieve what I described in my first post. I want to be able to manipulate premise and rule channels of L-system SOP via Python.

[danilo2]

something like that?

lsys.hipnc

pytest1.otl

Thanks for the files. This is quite close to what I was looking for. I originally want to modify the lsystem node without specifing a node path. I am trying to modify an lsystem node that is connected to a python sop. So the Python sop modifies channels of a node that is connected to itself directly.

Thanks for the files again, they have helped me to figure out couple things.

No problem

you want to write:

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

look at the documentation
