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 due 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 another 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 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.
- Under the hierarchy of the object named Static and Dynamic, which are the children of the aforementioned object. Place all objects according to the table below.

Static

Objects to be included

Objects containing non-moving meshes

Static setting (including child objects)

static

Dynamic

Objects to be included

Objects that can be moved or manipulated

Static setting (including child objects)

dynamic

example of objects belonging to Dynamic
- Animated objects (including not only move and rotate but also all changes such as show / hide)
- Pickup object
- ParticleSystem
- AudioSource
- Rigidbody
- Objects containing UdonBehaviour
- Objects that are operated by UdonBehaviour, such as moving and switching Active

※1: If Batching Static causes a distorted appearance, you may choose to remove it.

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 with VketTools.
- Manmaru Sheda MnMrShader3_1_2
- Unity-chan Toon Shader 2.0.8
- Unlit_WF_ShaderSuite_20210905
- MToon v3.7
- UniUnlit in UniGLTF_VRMShaders-0.81.0_5126

- ArxCharacterShaders(AXCS) Build17
- Xiexes-Unity-Shaders v3.0 2p1
- Silent's Cel Shading Shader v1.10
- Mochie's Unity Shaders v1.17
The above shaders do not need to be included in the submission folder.
If you use the above shader with a different version or a modified script, be sure to use a duplicate and include it in the submission folder.
When creating your own shader, you cannot use your own shader keywords other than the Unity standard.
_CameraDepthTexture cannot be used.
When using Emission with the Standard shader, set Global Illumination to Baked.
