Hi,
I have accidentally deleted a scene in my project (id: 736977)
By chance, i have done a backup download using the REST API of the deleted scene 1 hour ago (id: 1070754).
I have downloaded a backup of the entire project. I have tried to re-add the deleted scene in the project, but i have an error during the import “Invalid hash for scenes.json”
Is it possible to recalculate the hash of this file and give it to me ?
Thanks by advance
Regards
What you can do is import your backup to a new project. Open up the deleted scene, copy the entities in the deleted scene, create a new scene in the actual project and paste the entities.
TLDR, you can copy and paste entities between scenes and projects.
The backup i have is only a scene, not the entire project…
What i have understand is that i can only import previously exported project, and not scene…
What i tried to achieve, is modifying an exported project by re-adding the backuped scene, and re-import the project. The problem i have is the hash of the scenes.json file due to deleted scene added in it.
Do you have any checkpoints in version control of the scene?
No 
, just the initial one.
Hi,
it sounds like you haven’t downloaded a project archive but rather a build. We cannot recover a scene from a downloaded build - you can recover a project if you export it (from the dashboard) and then import it into a new project. You cannot download a backup of a single scene - it can help if you tell us which route of the REST API you used?
I have use this REST API : https://playcanvas.com/api/apps/download
and after this one for downloading the job : https://playcanvas.com/api/jobs/
This is for downloading an ‘app’ or a build of your project so you can self host it on your server. That’s not a project backup unfortunately. But you can view the json file of your scene to recover values you have set to components etc…
