Download latest isaac assets

I have mount my nucleus to the isaac assets on Amazon S3. It seems that the files there are read only. I am wondering if it is possible to download the latest isaac assets to my pc.

Yes, mounts are read only.
You can mount it to a different folder like “Isaac-mount” then go to the folder select all of it’s contents and right-click it. then select “Copy”.
Next, create a folder called “Isaac” and paste the contents there.
This a work around for the current version. We should have the download asset feature working in the next release.
