Opening file with pro assets without logging in or with non-pro account

I am wondering if it’s possible to open a project file that contains pro library assets while not logged in to the pro account or using non-pro account?

If possible what would happen with those placed assets? Will they be removed or hidden? Reverted back to default material? Locked (not editable) but still render-able?

Hi, yes, it is possible. If the model/assets have been inserted to the scene and saved, no matter what account you use to open them, they can work as normal. They will not be hidden or removed.
But if you do not use Pro account, you are not able to download other Pro assets.

Got it, thanks!
