load render preset with python issue

[Anonymous]

Hey I have an issue with scripting in maya with python. I want to load a custom renderpreset from a txt file but it only semi works.Reading the highlighted text from the notepad txt file

If I select a different renderer and go back to the maya softwarerenderer it has the correct settings.showing it works if I toggle the assigned renderer
The error stops the execution of the rest of the script though so I can't work with this!

Error: TypeError: file D:\Program Files\Autodesk\Maya2018\Python\lib\site-packages\maya\app\renderSetup\model\renderSetup.py line 700: Unknown keys found in the dictionary: mayaSoftware #

Used almost exact copy of this code:

Can someone help me? It's pretty urgent..

Hi,

I tried to reproduce the issue but failed. Could you send me a sample for reproducing the issue? It looks like rendersetup didn't find mayaSoftware render on your system and could be an environment setting problem.

Yours,

Li

from maya import cmds
import maya.app.renderSetup.model.renderSetup as renderSetup

import json

filename = "C:\Users\name\Documents\maya\Presets\TestPreset.json"

def importRenderSetup(pFilename):
    with open(pFilename, "r") as file:
        renderSetup.instance().decode(json.load(file), renderSetup.DECODE_AND_OVERWRITE, None)

importRenderSetup(filename)

 This is what I do in short, thanks for replying!

Hi,

It looks same as my test code.

import maya.app.renderSetup.model.renderSetup as renderSetup

import json

def importRenderSetup(filename):
    with open(filename, "r") as file:
        renderSetup.instance().decode(json.load(file), renderSetup.DECODE_AND_OVERWRITE, None)
 
       
importRenderSetup("e:/rendersetup.json")

The '\' character inside your path looks suspicious, it could escape some of characters in your filename path. Please try to replace them with '/'.

If that wouldn't work, it might be some special use case in the exported template. Could you send a copy of TestPreset.json to me?

Yours,

Li

Fixing the slash direction didn't change anything. Sent the files.

I fixed it by updating maya and adding missing code that cheng.xi.li provided to the preset json file. Thank you very much!

missing code from cheng.xi.li below

{ 
//Adding these into your file.
{
        "renderSetup": {
    "name": "renderSetup", 
    "renderLayers": []
  }, 
  "sceneAOVs": {}, 
  "sceneSettings": {
...
} // an extra bracket
}
}

Is there a solution to this? Tried using your code and still getting TypeError
