Unity Submission Rules

  • There will be various items in each shop.We would like to line up many gorgeous items and create a lively and fun space.
  • On the other hand, we will set rules for item creation to avoid issues associated with large-scale worlds.
    • Avoiding excessive load on visitor's PC for a smoother experience.
    • Avoid difficulties in checking and managing on the management side due to inconsistent formats.
    • Preventing certain operations that may destroy instances and cause fatal failures such as VRChat crash or being sent to a different world.
  • Before submission, please be sure to check whether it complies with the submission rules. Please use the submission tool (hereinafter referred to as VketTools) distributed from us for checking.
  • Items that fall under the following categories may not be placed.
    • Items that do not conform to the submission rules
    • Items that are judged by the organizer to be problematic such as high load
    • Items that deviate too much from the store theme
  • If you are submitting complex gimmicks or dynamically changing items, we may not be able to guarantee that they will work.

A. Item creation environment regulations

  • Create with Unity 2018.4.20f1.
  • For VRCSDK, use VRCSDK3 + Udon.
  • Use the latest version of VRCSDK and Udon at the time of submission.
  • Use VketTools to submit.
  • All the assets to be submitted should be placed under the exhibitor ID number name folder (e.g. 184) created directly under the Assets folder by VketTools.
  • Create the item on the scene with the same name as your exhibitor ID number inside 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 the files included in the Project should follow the above naming rule.
  • All file paths should fit within 184 characters under "Assets/" in Unity.
  • The mesh should be a file in a format that can be read by Unity standard such as ".FBX".
    • ".Blend" files cannot be read by default
    • Be sure to extract the Textures and Materials of the mesh
  • Total file capacity under the submission folder is within 100.00MB.

C. Scene internal hierarchy format regulation

  • All parents are empty objects with exhibitor ID numbers.
  • Only items in the following categories can use some of the Static settings. Items in other categories cannot be set to Static.
    • housing(prop)
    • housing(World minature)
  • The available Static settings are as follows.
    • Lightmap Static
    • Batching Static
    • Refrection Probe Static

D. Item rules

  • Item space following table.
    • The space should be based on (0.0.0) (example:In the case of 1m wide x 1m deep x 2m high,±1m in XZ direction, 2m in Y direction)
    • Z-axis + direction (Unity's blue arrow direction) is the front
  • Material following table.
    • Unity's built-in materials (e.g. Default UI material) are not included
  • Texture None.
    • Atlasification (integration) is strongly recommended
    • One large size (4k) is preferable to several small sizes (1k-2k)
  • The build sieze of asset bundle following table.
    • File size when only items are built with VRC_World in place
  • In order to reduce the drawing load, SetPassCalls and Batches should be kept to the following limits.
    • Base setting for SetPassCalls at runtime following table
    • Approximate base setting of Batches at runtime following table
  • Lightmap limit following table.
    • Objects with LightmapStatic checked (except for those with a ScalesInLightmap value of 0) that have an overlapping lightmap cannot be submitted
  • When placing, it may be rotated on the Y axis.
  • When the booth is placed, it will be placed in a location where the coordinates are not at (0,0,0)
