Glb file previously worked in 3D Capture, now fails with SIGSEGV

Cesium ion

Hi Cesium team,

I’m currently encountering a critical issue when uploading .glb files to Cesium ion.

Previously, I was able to successfully convert several terrain-based .glb models using the 3D Capture tiling option without any problems. However, starting this afternoon (KST), the same files are now failing to tile and return the following error:
Error: Internal Error Details: Process exited from signal: SIGSEGV

To confirm, I re-uploaded several terrain .glb files that were successfully tiled in the past using 3D Capture — but now they also fail with the same SIGSEGV error.

As a workaround, switching to the “3D Model” tiling option allows the files to process successfully. However, since these mesh-based models are intended to represent terrain surfaces, I would prefer to continue using the 3D Capture pipeline, which is more appropriate for this type of data.

Could you please confirm if there has been a recent update or regression on the Cesium ion backend, possibly related to the 3D Capture pipeline or 3D Tiles 1.1 support?

Thank you in advance for your help.

I’m sorry that’s not working for you.

I need an asset ID to look at a failing job; can you upload one of the failing GLB files, and provide me the asset ID that is created?

I have the same problem too. The Asset ID is 3481629. (I am not sure if this ID is private to me, but please let me know if more information is needed).

Thank you for the asset ID; that’s all I needed. I’ve created an issue for the tilers team to address.

Trying @sagarb’s asset, it tiled as expected. @junhochoi, can you provide an asset ID I can try?

Unfortunately, on my Cesium Ion, the asset ID 3481629 shows an error. A different asset that is just stuck at “14%” tiling progress is 3481660.

The Asset Id is 3475749. I appreciate your reply and assistance.
