render .aep data-driven mode with aerender

[Guest]

Hi every one. I want to make data-driven after effects project (.aep) file that the data are stored in json file. so that i can change the data in the json and the .aep get updated wuth new data. so far i made this with mamoworld plugin.

now i have a data-driven aep with json. if  i open the project in the AE, every thing is good an  if i make a change in the json, the opened project in the AE get updated.

the problem is that i want to render the project with aerender. when i use aerender, the aep in NOT getting updated data from json and get rendered with the initial data(the data that inserted in the project while in was built.).

sorry for bad english. it's not my primary language.

here is my aerender code:

aerender -project D:/latest/new/pr1.aep -comp "Comp1" -output D:/latest/new/video.avi

is there any thing that i missing? or some thing i'm doing wrong?

any guide or reference or anything that helps will be great.

That's a bug/ limitation. The expressions don't correctly update unless you open the project in the full AE. No way around it for the time being.

Is there any Other solution ???

Maybe launching AE by script to open and close it automatically and update everything by doing so?
