creator ntp automatic

I wish to create projects of automatic way for some animations.
I always have X layer that mix between if, to add effect in half.

example:

2018-04-30-211349_1600x900_scrot

It exists documentation of the XML or a way to create projects from bash?

See how we do it in the unit tests:

github.com

NatronGitHub/Natron-Tests/blob/master/TestPY/test___01.py

from __future__ import print_function
import NatronEngine

f1 = open('test___01-output.txt', 'w+')

reader = app.createNode("fr.inria.openfx.ReadOIIO")
writer = app.createNode("fr.inria.openfx.WriteOIIO")
blur = app.createNode("net.sf.cimg.CImgBlur")

reader = app.Read1
writer = app.Write1
blur = app.BlurCImg1
print(blur.getScriptName(), file=f1)

reader.filename.set("input1.png")
writer.filename.set("output#.jpg")

writer.connectInput(0, blur)
writer.formatType.set(0)
writer.frameRange.set(2)

thanks!, It is just what wished. I go to test with my project.

Where can download NatronEngine for gnu/linux?

devernay · May 4, 2018, 7:06pm

It’s installed with Natron

bazza · May 5, 2018, 3:24am

I am not very programmer.
As I can test it?

the executable is called NatronRenderer on Linux and macOS, and NatronRenderer.exe on windows. It is installed at the same place as the Natron executable.

Very good. But this does not create an file “.ntp”

You can save the project from the python script:

app.saveTempProject('tmpScript.ntp')

see

github.com/MrKepzie/Natron

Open, save, rename project within Python API.

Hi. I am writing a node (group) that can send jobs to Afanasy render farm manage…r. Node approach has much advantages, you can store different render settings by saving several nodes. You can connect several write nodes with afanasy node to (re-)render all "precomps" at once with a specified dependencies, ( for example "key" and "back" precomps than "final" to compose them together ). It is a good practice for an any render manager (submission script) to store current scene to a temporary file (usually just placed in the same folder with some suffix) just before job creation. This way an artist can continue to work with an original scene and save changes. And there will be no mess with various versions frames in the same sequence. Artist should sure that the result will represent exactly the version at the moment that job was sent (all frames). btw All other CG soft that i used with Afanasy has such scripting functions :) At least any soft can just save scene (this way i can just copy file with a new temp name) ps Nuke has "nuke.scriptSave([scenename])" :)

Already almost i have it, only that no as do a view:

viewer = app.createNode("fr.inria.built-in.Viewer")
viewer = app.Viewer1
viewer.connectInput(0, blur)

And reformat param for 1920x1080

Sorry, I don’t understand your last question?

bazza · May 7, 2018, 9:17pm

I can create a project
I want to add a viewer
I wish to modify the reformat in 1920x1080

Note: I am to automate by that i have to create 100 projects roughly

you could write a python script that creates your Natron graph. You probably know the number of cameras and even the number of frames, so write something like this (or write a script that creates a script like this): Natron-Tests/test___01.py at master · NatronGitHub/Natron-Tests · GitHub and at the end of the script save the project using
app.saveTempProject(‘tmpScript.ntp’)
Then run the script through “NatronRenderer -l myscript.py” and it creates tmpScript.ntp
Doc for writing scripts is here:
http://natron.readthedocs.io/en/rb-2.3/devel/index.html
you could write a “toolset pyplug”, which is a python script that can be executed from the Natron GUI. The python code is in the createInstance function. One example is this one, which is included in Natron: Natron/SplitAndJoin.py at RB-2.3 · NatronGitHub/Natron · GitHub
doc is here: http://natron.readthedocs.io/en/rb-2.3/devel/groups.html toolsets are mentionned at the bottom

I am sorry, but I really do not have more time for this.
