After Effects warning: std::exception

[machii6]

I'm using Mac, the app has operated well, but this error showed up while I was previewing my video. 

How can I resolve this issue?

[jenkmeister]

Is it one particular piece of footage/video? What are the steps to reproduce this? 

[machii6]

This issue is not related to a specific piece of footage or video file. The error occurs regardless of which media I use.

It only happens when I add a Repeater to a shape layer to create an infinite tunnel loop effect. If I hide that layer, the preview works fine.

Steps to reproduce the issue:

1. Create a shape layer (e.g. a rectangle or ellipse)

2. Add a Repeater to that shape layer

3. Adjust the Repeater’s transform properties to create a tunnel effect

4. Press spacebar to preview → the std::exception error appears

Please let me know if you’d like me to share the project file or exact Repeater settings I used.

Can you make an AE Project and make that available for me to download. I tried to follow your steps but I'm sure I don't have the repeater setup to reproduce this.

this is my project, you can find the repeater setup in layer 12 around 13 seconds onwards.

Excellent, thank you. I have been able to reproduce the issue. I will figure out what's going on, see if there are any workarounds, and look at getting this fixed in an upcoming AE release.

I'm having this same issue. Have you found anything?

[jenkmeister]

@andrewsriddle Is your issue specifically to do with a repeater being used, or is it a different instance of "std::exception" being shown? 

[jenkmeister]

I have identified the original problem. It is related to the shape repeater internally creating some calculations that cause the downstream rendering to go wrong. You can fix this right now in your comp by changing your "infinitive tunnel loop" final keyframe for offsets to -14.0. Anything beyond that is triggering the issue. 

The fix will be in a future version of After Effects, where it will stop the crash from happening and alert you to the problematic layer, frame, etc.

My issue is a bit different. I'm not sure where to begin finding the problem because it's a fairly loaded project, and I'm an intermediate AE user. Every time I use the text tool in this project, it gives me this error in an endless loop. To get out of the loop, I either force quit AE or spam enter "ok" while trying to click a different layer to get out of the error notification loop. This project contains tracking, keying, pre-comps, etc. Once I'm out of the loop, everything is fine except if I select the text layer, it throws me back into the notification loop.

@andrewsriddle If you're able, try out the AE Beta which you can download from the Creative Cloud Desktop app. There is a fix for the std::exception never ending loop problem, and if you enable Logging (Help -> Enable Logging), that may be able to tell us what is causing the error for you.
