Filling in the package details

When you create a package draft, the Create new package window appears, containing several sections where you can fill out information about your package. These sections are also available every time you edit your package draft, but you must complete all required sections before submitting your package for approval.

The topics on this page provide instructions on how to fill out these sections:

Package Detail

The Package Detail section lets you set the version (with description), category, and price for your package.

Note: Although the package title appears in the Package Detail section, you can only change it in the Metadata section.

Information: Description:
Status Current status of the package (including Draft, Published, Declined, and Pending).
Version The version number for your package (such as 1.5, 1.6, 1.7). New Asset packages should use the default version 1.0.

When you release updates for your Assets, you can increment the version number here. For example, if you need to fix a bug, change the minor version number (1.3 to 1.4). If you introduce a big change, change the major version (1.3 to 2.0).
Version Changes Describe any updates that triggered a version change, such as bug fixes, new Assets, or changes to match a new version of Unity.
Category Choose a category that best fits your package, because when customers look for Assets on the Asset StoreA growing library of free and commercial assets created by Unity and members of the community.

Price USD You can set a price of $4.99 or any higher amount in US dollars. For any lower price, enable Free instead.

When you are finished, click Save.

Metadata & Artwork

The Metadata & Artwork section lets you set the name of the package, and provide marketing images, audio, and video to add branding for your package.

The artwork (key images, audio/video, and screenshots) are shared across all languages.

You must set an English name and description, but you can also specify a name and description in Japanese, Korean, and Chinese; to do this, click the links under the Language column. When you add a language, a new Edit link appears under the Metadata column for that language.

You can only edit Tags after your package has been accepted for publishing.

Metadata

Metadata includes the name, description, and keywords for your package: that is, anything to help customers find your package while they are browsing or searching the Asset Store.

To edit the name and description of your package:

  1. In the Metadata & Artwork section, under Metadata, click the Edit button.

    The Metadata page for a specific language appears:

    Set the Title, Description, and Keywords on the English Metadata page

    and the user needs to import them separately.

You can decorate this text with any of the following HTML tags:

  • EM (for italics). For example: This is for <EM>italicized</EM> text.

  • STRONG (for bold). For example: This is for <STRONG>bold</STRONG> text.

  • A (for hyperlinks). For example: This links <A HREF="http://www.example.com">here</A>.

  • P (to define a paragraph). For example: <P>This is a new paragraph</P>.

  • BR (for a line break). For example: This is the first line.</BR>This text appears on the next line.

  • You can optionally add a list of Keywords separated by whitespace to influence your Asset’s results in Asset Store searches. There is a limit of 255 characters.

  • Click Save when you are finished and then click OK when the dialog box appears.

  • To return to the Package window, click Go Back.

Key image

Key images should indicate what your Asset package does and help it stand out. You can set four different resolutions so that your key images appear as icons or thumbnails when customers browse or filter the list of packages available in the Asset Store, and as larger images on the main product page or on social media. These also might appear in promotional material.

Here are some general requirements for the images you upload in this section:

  • The images cannot contain the following:
    • Unity logos
    • Sale banners
    • The default Unity SkyboxA special type of Material used to represent skies. Usually six-sided. More info
      See in Glossary
      (for example, as a background)
  • The images must not be blurry, stretched, or cropped.
  • The images cannot only be screenshots of the Unity Editor.
  • You should make different designs for images of different sizes so that the objects or visuals in the icon and card images are legible and separate.

This table describes the different images, where they might appear on the Asset Store and specific requirements for each:

Key Image Type: Size (in pixels): Description:
Icon 160 x 160 The Icon image is visible while users are browsing the Asset Store using the icon grid layout. This image should not contain text.

Note: Icon images must be 160x160, even though the actual display size is 80x80. At 80x80, image text is not readable, but uploading the larger size lets the Asset Store display icons clearly at the smaller size.
Card 420 x 280 This is the main thumbnail visible on your Home page and the default view while browsing the Asset Store. This image can have only the following text:
- Title of the Asset
- Logo or name of the publisher

Note: Like icon images, Card images must be uploaded at a larger size (420x280) than the size of image that ultimately appears on the Asset Store.
Cover 1950 x 1300 This is what customers see on the main product page for your package. This image can have only the following text:
- Title of the Asset
- Logo or name of the publisher
- A tag line

Note: Like icon images, images must be uploaded at a larger size (1950x1300) than the size of image that ultimately appears on the Asset Store.
Social Media 1200 x 630 The Unity community team might post these images to social media, or on the Asset Store home page. This image should not contain text.

For more information, see the Asset Store FAQ.

To set one or more key images:

  1. In the Metadata & Artwork section, under the Key Images column, click the Edit button.

    The Key Images page appears:

    Set the Icon, Care, Cover, and Social Media images on the Key Images page
    Set the Icon, Care, Cover, and Social Media images on the Key Images page
  2. To upload an image, click Choose File or drag and drop the image onto the gray box.

    Note: The image must be the exact size as indicated.

    The uploaded image appears with a Remove button under it, which you can click if you need to remove that image.

  3. To return to the Package window, click Go Back.

Audio/Video

You can upload audio or video files that demonstrate what your Asset Store package does or contains. These are available on your main product page (as thumbnails you can click on to play).

Note: If your package contains audio or video files, you must upload samples of your media Assets here. If your package contains tools, scripting, or other technical Assets, include a video tutorial explaining the setup process, and give an overview of your Asset’s functionality. If your package contains animations, include a video of all the available animations.

You can embed uploaded files in the show reel with the screenshots of your package. Audio and video files can come from either your local computer or device, or you can specify links to any of these services:

To set one or more key images:

  1. In the Metadata & Artwork section, under the Audio/Video column, click the Edit button.

    The Audio/Video page appears:

    Add audio or video files or a link to online media on the Audio/Video page
    Add audio or video files or a link to online media on the Audio/Video page
  2. You can upload audio or video files using any of these methods:

    • Drag-and-drop the file onto the gray box.
    • Click Choose File to select the file from a file browser.
    • Enter a link to an online file in the text box and click Upload link.

    The uploaded image appears with a Remove button under it.

  3. To return to the Package window, click Go Back.

Screenshots

You can upload screenshots of your package’s Assets in action. These are available on your main product page (as thumbnails you can click on to enlarge).

Screenshots are just as important as key images when trying to sell your package. Screenshots showcase your package, showing users how it works and what it can do. Users often use screenshots as a kind of package preview before they actually buy it. Asset Store curators prefer having screenshots for most Assets. For example, if it’s a Model, add images that display the Asset from different perspectives, both fully textured and in wireframe.

To set one or more screenshots:

  1. Click the Edit button under the Screenshots section.

    The Screenshots page appears:

    Add screenshots from your package on the Screenshots page
    Add screenshots from your package on the Screenshots page
  2. You can upload one or more screenshots using either of these methods:

    • Drag-and-drop the file onto the gray box.
    • Click Choose File to select the file from a file browser.

    The uploaded image appears with a red X icon (to remove it) under it.

  3. To return to the Package window, click Go Back.
