I’m sorry for the issues you stumble upon! Can you please share the job URLs? They hold the job IDs which we’ll use to locate the jobs in our backend system and investigate the cause of their failure. If it’s more convenient for you, you can share the URLs in a direct message to me here in the forum.
The error which causes the job to fail is out of memory. Can you please share the scene with us so we can have a look and advise you if there is a way to optimize it and avoid this error? You can do this in a direct message to me here in the forum.
The best way to share the scene with us is to send us a ticket from here - there is an option to upload a big archive with the scene and its assets as well. If you go this way, please mention this forum thread in the description. Please let me know if this works for you.
