Hi,

What I'd like to do is the following:

- I have an L-system that generates an L-system string, as usual
- I want to take this resulting string and use as a Premise in another L-system

Is this possible somehow?

Cheers,

imre

While very dirty:

opinfo = hou.hscriptExpression('run(“opinfo /obj/geo1/lsystem1”)')
lsysStart = opinfo.find(“LSystem string:”)
lsysEnd = opinfo.find(“_______”, lsysStart)
return opinfo

this will grab the expanded string from one lsys and then you can have that in the premise parameter of the 2nd lsys. Remember to keyframe this since otherwise the python wont work in the string parm. Not sure if there is a cleaner way of doing this, maybe a custom expression function via the hdk could wrap this up nicer. There are some re-cooking issues so if you need it animated keyframe one of the rules on/off checkboxes in order to force string-reevaluation on the 2nd lsys.

Best of luck,
Fabian

Well… That's what I was afraid of… Anyhow, thanks (maybe I log this as an RFE)

I suppose it might be a bit cleaner if you dumped the string into a spare parm on lsys1 and then just do a channel reference in lsys2. But yeah, nothing nice and in-built there. I think generally feeding lsys into each other via the additional inputs is a better way to go.
