Submission Rules(General)

• 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.

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 4m wide x 4m deep x 5m high
• ± 2m in the XZ direction and 5m in the Y direction with respect to the origin
• Z axis + direction (the direction of the blue arrow in Unity) is the front
  
• No limit on the number of textures
  • However, atlasing (texture integration) is strongly recommended.
  • One large size (4k) sheet is preferable to multiple small size (1k-2k) sheets.
• AssetBundle build size within 10.00MB
  • 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.

E. Shader regulations

• The shaders listed below will be distributed by the organizers along with VketTools.
  • Manmaru Sheda MnMrShader3_1_2

• When creating you submit with shaders other than those listed above, please follow the below restrictions.
  • Global keywords like (shader_feature, multi_compile) cannot be used. Please use local keywords like (shader_feature_local, multi_compile_local) instead.
  • Shaders with _CameraDepthTexture cannot be used to avoid issues of VR camera display.
    • Scripts inside the Editor folder should not be put inside the submission folder.
    • When using the Poiyomi Shader, Lock the shader and submit the generated shader file only.
• When using Emission with the Standard shader, set Global Illumination to Baked.
• When using Stencil, keep the number of Stencil buffer to be not more than 200.
