Some discussions attached:
to init.py file doesn’t produce any result, nor any error message.
Note that every other parameter can be accessed and tweaked using the ‘getProjectParam’ function.
I was wondering how curves work with python scripts. have you somes examples ? Even if i add somes animations on an effect, i don’t understand how i can edit curve, and i don’t see it in curve editor (ui).
Is it even possible ?
I’m trying to get the ‘diskCachePath’ setting.
I’ve tried using the ‘NatronEngine.AppSettings.getParams ()’ for the ‘AppSettings’ class.
But script returns an error saying ‘getParams ()’ needs an argument, although doc says it doesn’t require any.
If anyone has any clue on this.
So I’m learning how to navigate Natron with Python, and having trouble. What I’m trying to do is pick an output format in Natron settings. I’m under the impression that before I pick a format, maybe I need to see what formats there are first, therefore, I’m trying to read Natron’s settings via code. According to the docs, NatronEngine.AppSettings.getParams() “Returns a sequence with all Param composing the settings.”. Yet, when I run that function, I get the following error:
The ‘DiskCache’ has its ‘Last Frame’ parameter to be named ‘LastFrame’ with a upper case ‘L’, instead of lower case.
Seems to me like a bug.
I try to automate Natron for our studio. But I have a problem with printing some message in ScriptEditor console:
how can I fixet this output? Is the onle way use loging for debug scripts

I’m having difficulties getting the app1/app global variable when running a custom python script.
I’m receiving this error:
NameError: global name ‘app1’ is not defined.
Note the script works when running in Natron’s interactive python shell it works.
I tried a few approaches, but none have worked so far:
I receive a different app instance, which has a subset of the functions app1 has.

I am looking for a way to reference existing node from python inside the GUI (script editor). From the examples/documentation, I extracted the following:
from NatronGui import *
app = natron.getInstance(0)
Nice! A node named “Write5” appears on the Node Graph, but when I try to get it later from another script…

AttributeError: 'NatronEngine.App' object has no attribute 'Write5'
So this is the documented way, …
Hey there, simple question. As i am new to natron - is it possible to export a GUI-Node-Graph project as python-script for use on command line? Background is: i want to start an in natron with gui done project, but also with flexibility on give command line based parameters such as tell a text-node what text should be shown?
So for now I really only need command line without GUI. So I Do have my ntp file with a simple text which scales up about 5 percent. Is it with the natronrenderer out of th…
This expression is incorrect. Multi-line expressions look like this:
if frame < 150:
ret = frame * 10
ret = 150 * 10
See the tooltip for the “Multi-line” button:
"When checked the Python expression will be interpreted as series of statement. The return value should be then assigned to the ret variable. When unchecked the expression must not contain any new line character and the result will be interpreted from the interpretation of the single line.
