【Unity2019】Methods for Resolving Issues that Occur in Developed Scenes Converted from STYLY to STYLY 2.0

In this manual, we will explain in detailed steps how to resolve the incompatibility issues when converting scenes created using Unity2017 from STYLY to STYLY 2.0.


With the latest update, STYLY will officially upgrade its supported Unity version from Unity2017 to Unity2019.

Through this update, STYLY will be upgraded to STYLY 2.0.

Users and artists can read more details regarding this update in the following article.


Most of the uploaded Prefabs and Scenes, which have been developed using Unity2017, will work correctly in STYLY 2.0. However, a few of these developed Prefabs and Scenes may encounter compatibility issues with the latest update. These issues may include incorrect operations or abnormalities in appearance.

Users and artists can find more detailed information regarding these issues in the “Resources Incompatible with STYLY 2.0” section from the article above.

Artists and users should load and re-upload their developed Prefabs and Scenes using Unity2019 should they encounter these compatibility issues.

Below, users can find detailed steps for fixing these issues.


Regarding the Publish Function and Positioning Assets within STYLY Studio

Users and artists should take note that assets created and uploaded from Unity2019 may not be compatible with the old version of STYLY. Therefore, artists and users should only retry positioning their assets and use the Publish function in STYLY Studio after STYLY 2.0 has been officially released.

(All of the announcements will be made via STYLY’s official Twitter account and other similar platforms)

Editing STYLY Scenes Which Have Been Published Via the Publish Function with STYLY Studio

Users and artists who do not want to change the URL of their developed STYLY scenes because these URLs are being used on an external site (for example, embedded on a particular page) can directly edit their published scenes.

However, please note while assets uploaded and replaced directly from Unity2019 may immediately take effect in published scenes, these assets may not work correctly in STYLY 2.0.

As specified previously, users and artists should only reposition assets in STYLY Studio once STYLY 2.0 has been officially released to ensure that all of their assets will work correctly in this latest version.

Testing with STYLY Studio 2.0 (β Version)

Our team will provide all users and artists with another URL leading to STYLY 2.0’s β Version with which they can test their projects for any compatibility issues using STYLY Studio.

However, users and artists should not directly edit their published scenes. It’s recommended that artists and users should copy their published scenes and try to reposition their assets in these newly created scenes to verify compatibility issues.

Please note that any scenes whose assets were repositioned using this β version will not work correctly with STYLY (Official Version) before STYLY 2.0’s official release.

Detailed Steps for Transitioning Using Unity2019

The overall flow for transitioning to the new engine is described below.

Creating Backups for Your Projects

Before opening your projects using the newly installed Unity2019, it’s recommended to create backups for them while retaining their conditions as when created using the previous versions.

This action ensures that no errors could cause harm to your projects. As projects created using Unity’s earlier versions are opened in the latest versions, they will be automatically converted into the newest file format to ensure the best compatibility with the latest editor. This also means that your created data will be altered.

This alteration will also cause the previous editors to be unable to open your projects should it be necessary to edit your projects using earlier editors.

Even in other cases, especially when it’s necessary to come back and make extensive changes to your projects, it’s a good habit to create multiple backups.

Even though we called it backups, all you have to do is to simply make a full copy of the folder containing your projects.

However, since we are making a full copy of a folder, it’s necessary to check beforehand to ensure that your computer has enough free space for further operations.

※It’s recommended closing Unity first before making a full copy of your projects’ folder

※Users can skip this step in case they are managing their projects using distributed version control systems such as git, or in case they believe it’s unnecessary to create backups.

Opening Your Projects with Unity2019

Next, proceed to open your projects using Unity2019.

Open the “Projects” section in Unity Hub’s panel. At this stage, your list should still be empty.

To open created projects, click on the “Add” button.

Unity Hubでプロジェクトを追加

Adding projects to Unity Hub

From the newly opened dialogue, choose the folder containing your project to add it to Unity Hub.

You can now choose the “Unity Version” to open your added project. In this case, select Unity2019.3.3f1 as your desired version.


You can choose the version of your Unity editor with which to open your projects



Choose the version of the editor to open your projects


The displayed Unity Version will be changed into the version you’ve selected

After having changed into your desired version, open your project by clicking on the row containing your project’s information.

You will receive a warning similar to the following. Make sure that you’ve created a backup for your projects before clicking on the “confirm” button to proceed.

Unity Hub’s warning

The project should now be opened with your newly selected Unity’s editor.

Most of your project’s data will be converted into the latest format. This process may take some time.

Script Errors Occurred After Opening Projects with Unity2019

After opening your projects with Unity2019, you may encounter script errors (compiler errors) that prevent you from running your created scene.

For example, if the error was caused by PlayMaker, you can resolve this error by reimporting the PlayMaker.

To reimport PlayMaker, first, close the current Unity session. From Explorer, navigate to the “PlayMaker” folder, go to “Plugins,” and delete the “PlayMaker” folder here. Then, restart your Unity editor and reimport PlayMaker.

(Please take note of any additional PlayMaker templates that you may have inside your PlayMaker folder before deleting it)

Upload Your Projects with Unity2019

After launching your project with Unity2019, check for any errors and issues that may occur with the data to be uploaded.

Repair and readjust any data and parameters that may require adjustments using Unity2019.

There’s also a version of the STYLY Plugin for Unity2019 to upload.

You can download and import from the download link in the article referred to in the “Overview” section.

After importing the latest plugin, users can follow the usual steps to upload their projects.

Once the upload process has been completed, typically, you can begin positioning the uploaded assets in STYLY Studio and confirm their operations.

However, as mentioned previously, our team advice all users and artists to refrain from positioning your assets before the upgraded official version of STYLY Studio has been released. At the moment, please stop at uploading your projects to STYLY.


Users and artists who have forgotten the steps for uploading their projects can refer to the article below.

Editing Scenes in STYLY Studio 2.0 (β Version)

As mentioned in the caution section, users and artists should create a copy of their scenes in STYLY and replace the assets in these scenes with the newly uploaded assets to test their operations in STYLY Studio 2.0 β Version.

Testing your projects with STYLY 2.0 (β Version)

Now, you can continue to verify your created scenes for any compatibility issues with STYLY 2.0 β Version’s VR Application and Web Player.

Waiting for STYLY 2.0’s Official Release

Please kindly wait for the announcement of STYLY’s official release.

Editing Your Scenes with STYLY Studio 2.0

After the newly upgraded STYLY has been officially released, users and artists and proceed to edit their scenes using the officially released version instead of the provided β version.

Only after this step can published scenes be edited.

Delete all of the old STYLY assets, which are now incompatible with the new release, and start positioning and developing your projects using the newly updated Unity2019 compatible Prefab and Scene.

Also, at this point, you can publish your developed projects with the Publish function.

Testing Operations in STYLY 2.0 (Official Version)

With the latest official release, the latest version of STYLY Application (VR Application) will also be released. Update your current application and use this to test for various operations if needed.
