Publishing error: You are attempting to publish a world with pre-release features.

Hi,

I have a World and I want to participate in the Creator Competition: Elevate Your Mobile World. When I try to use new features—such as importing an FBX file or inserting assets with the new format—there is no problem in previewing the World. However, since my World was originally created in 2022, I receive the following error message when attempting to publish:

"You are attempting to publish a world with pre-release features."

It seems that new features are recognized as pre-release features in worlds with older original metadata or internal structure.

Even if I delete all entities and scripts in the World except for the imported FBX or inserted asset, I still receive the same error when I try to publish it.

On the other hand, if I create a brand-new World and import the same FBX file or insert the same asset, publishing works fine.

Additionally, in my older World, I can't assign custom textures to shapes, and the Build > Shapes menu lacks newer items like Cube Beveled or 10 x 10 Plane.

Since the competition requires updating a previously published World, what would you suggest? Can I recreate and update my World from scratch to avoid the publishing error? If I do that, the new World would not meet the requirement of being originally published before June 30, 2025.

Any guidance would be greatly appreciated.
Thank you in advance!

Hi Navid.64​, I'm sorry you're running into issues with publishing your updated world.

It sounds like your original world was a Primitive world, and you now need to convert it to a Custom Model Import world in order to publish with your new imported models. You can follow the instructions in this article, to replace your existing world with the changes you have made and still retain likes and visits from the original world.

Be sure to make backups and duplicates of the original world and the new world before starting this process in case you run into any issues.

Thank you Ben.SH​  for your guidance. When I follow the instructions in the article you sent, at step 7, there is no "Import World" option. Only the following 4 options are available:

Duplicate World,
Delete World,
Preview World,
Shutdown Server

Could you please let me know how to proceed?

Could you send a screenshot of your view?
Also, make sure you are in preview mode of the primitive world when attempting the import.

I tried both preview mode and outside editing mode. In preview mode of my Primitive world there are 3 options and "Import World" is missing again. Here is the screenshot of the preview mode:

Thank you again Ben.SH​ for your guidance! It was my mistake—I opened the Primitive World menu instead of the CMI menu. Now it has "Import World" option.
