Submission Rules: Space Exhibition

This page contains the submission rules for Space Exhibitions.
Please review this information when applying for an exhibition or submitting materials.

• For Udon regulations, please refer to Udon Regulations: Space Exhibition.
• The contents of this page may change or be updated due to rule revisions. Please review the information again before submitting your work.

Worlds for Space Exhibitions

• PC Venues
  • Deep Mist
  • Ohh-Edo! MECHANICA
  • VOLTAGER
  • Cocoon Art Aquarium Redive
  • Argdella Rediscovered
  • SKY PARK-Renew
• Space Exhibitions will be open on each PC Venues listed above.

Submission Rules Overview

• 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 PC hardware
  • Avoid inconsistent formats that will cause difficulties for the organizers to check and manage the data
  • Avoid fatal bugs such as instance crashes leading to VRChat crash, or returning to other worlds
• Before submission, make sure to check the compliance with the submission rules. Please use the submission tool (hereinafter referred to as VketTools) provided by the organizer.
  • VketTools will be distributed on your Submission Management page once the Submission Period begins.
• If the submitted space does not comply with the submission rules, the organizers may request a resubmission or decline placement.
• Even if the space complies with the submission rules, if the space is deemed problematic such as taking up a high load, the organizers may request resubmission.
• When submitting complex gimmicks or dynamically changing spaces, we may not be able to guarantee reproduction.
• In the case of spaces 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.
