Problem with rendering the video, which contains expressions referring to other compositions

[Yunseo5CD5]

Hello, the newest media encoder version in macOS(Sequoia 15.0) has a problem rendering the AfterEffects composition, which contains expressions referring to other compositions. This problem occurs ONLY in MacOS.  (Windows works well)

It works fine in the After Effects preview and the After Effects renderer (lossless). However, as soon as I start rendering with Media Encoder, the plain video(H.264), which isn't applied the expression comes out.

How to reproduce the error

The problematic expression is simple:

Please test using the expression below.

1. referring to other compositions in the object expression

comp("otherCompName").layer("something").position[0]

2. render the composition, which contains the expression above, using a media encoder

(So that you know, I used many expressions in my project under the problematic  situation.)

Additional information: The latest After Effects and Media Encoder versions are 25.1.

I'm sorry for the delay in delivering this information.

Hi Yunseo5CD5,

I just did a test as per your description, and it exported a file using Media Encoder. I am on a Mac with M2 Max. Can you test it in on a new project? If the issue persists in the new project, please share it with us for testing. If it doesn't, it could be a project-specific issue.

Looking forward to your response. Moving this thread from Bugs to Discussions for troubleshooting.

Thanks,
Nishu
