Submission Rules(Quest Vket Academy)

• A large number of spaces will be set up at each venue. We would like to have many gorgeous spaces lined up in a lively and fun venue.
• Meanwhile, to deal with the problems inherent to large-scale worlds, we will set rules for space creation.
  • To maintain a comfortable playing environment for visitors by avoiding high load on the PC
  • Avoid inconsistent formats that will cause difficulties for the organizers to check and manage the spaces
  • Avoid fatal bugs such as instance crush resulting in VRChat crush or returning to other world
• Before submission, make sure to check the compliance with the submission rules. Please use the submission tool (hereinafter referred to as VketTools) distributed from the organizer.
• Please note that if the submitted space does not comply with the submission rules, the organizers will take measures such as resubmission request or non-placement.
• Even if the space complies with the submission rules, if the space is deemed problematic such as taking up a high load, a resubmission may be requested by the organizers.
• When submitting complex gimmicks or dynamically changing spaces, we may not be able to guarantee reproduction.
• In the case of space with a significantly small amount of information, the exhibitor may be asked to confirm after the submission period, and the space may be removed only if the confirmation cannot be obtained.

About Quest Venue

• Quest Venue world will go through two separate builds for PC and Quest. Due to texture compression issues, the submitted space may look a bit different in PC build and Quest build.
  • In particular, smaller texts may become illegible by the compression. We recommend to use Text or TextMeshPro components.
• In Quest build some gimmicks may not function or have different behavior.
  • The VketWebPageOpener will not launch webpage in the Quest.
  • To play a video in Quest you need to set the URL to be a direct link to .mp4 format video file.
• The Quest venue world will be visited by players playing the VRChat with Oculus Quest. Please avoid such a situation that your main exhibit is available only on PC-version VRChat or SteamVR.

A. Space creation system regulations

• Create with Unity 2019.4.31f1.
• For VRCSDK, use VRCSDK3-WORLD.
• Use the latest version of VRCSDK and Udon at the time of submission.
• Use VketTools for submission.
• All assets used in the space should be placed under the [exhibitor ID] folder (e.g., 184) created directly under the Assets folder by VketTools.
• Create the space on the [exhibitor ID] scene found in the above folder.

B. File & Folder regulations

• Only half-width alphanumeric characters,-(hyphen), _ (underscore), (half-width space), .(Dot), and () (parentheses) can be used for file & folder names.
• All files included in the Project should follow the above rule.
• All file paths should fit within 184 characters under "Assets /" in Unity.
• The mesh should be in such a format that can be used in Unity by default, such as ".FBX".
  • ".Blend" files cannot be read by default.
  • Be sure to extract the Textures and Materials of the mesh.
• Total file size capacity under the submission folder is within 100.00MB

C.Scene hierarchy structure regulations

• All objects included in the space should be arranged and set according to the following regulations.
  • Every object should be children of the [exhibitor ID] object.
  • Objects should be placed under the objects named Static and Dynamic, which are the children of the aforementioned parent object.

Static object

• Objects with the below property should be placed under the "Static" object.
  Fixed object with unchanging mesh
• All objects inside the "Static" object should have the Static settings defined below.

Dynamic object

• Objects with the below property should be placed under the "Dynamic" object.
  • Objects with animations, including all changes like Enable/Disable as well as movement and rotation.
  • Objects that can be Pickup
  • Objects with ParticleSystem
  • Objects with AudioSource
  • Objects with Rigidbody
  • Objects with UdonBehaviour
  • Objects controlled by UdonBehaviour like movement or Active switch
  • Any other objects that may move or be subject to controls
• All objects inside the "Dynamic" object should have the Static settings defined below.

D. Space regulations

• Your space must be contained within the boundary of 2m wide x 2m deep x 2.5m high

• ± 1m in the XZ direction and 2.5m in the Y direction with respect to the origin

• Z axis + direction (the direction of the blue arrow in Unity) is the front
  

• The number of textures is limited to 8

  • However, atlasing (texture integration) is strongly recommended.
  • One large size (4k) sheet is preferable to multiple small size (1k-2k) sheets.

• Texture limitation

  • Please set the pixel size of each texture to be multiples of four, both vertically and horizontally.
  • The pixel size of all textures must not be larger than 4096 * 4096.
    • e.g. single texture of 4096 * 4096 size: acceptable
    • e.g. two textures of 2048 * 2048 size and two textures of 1024 * 1024 size : acceptable
  • Please disable Override for Android on the texture import setting.
    • On the Quest build, the organizers will impose a uniform texture compression setting.
    • We are planning to use the ASTC6x6 format for compression, but depending on the drawing load we may opt for stronger compression formats like ASTC8×8.

• AssetBundle build size within 5.00MB

  • This is the file size when building the space with only VRC_World in place

• SetPassCalls and Batches should be lower than the following values to reduce the drawing load.

  • Run-time SetPassCalls reference value 20
  • Run-time Batches estimated reference value 30

• Lightmap limit: not more than 1 sheet of smaller than 512 x 512 pixels

• Among the objects with ContributeGI checked (except those with ScalesInLightmap value of 0), those with overlapping lightmaps cannot be submitted.

• Upon placement, the space may be rotated on the Y-axis.

• Upon placement, the coordinates will be different from the origin.
