Analysis of Access Control Mechanisms in VRChat Avatar Distribution

Date: October 26, 2025

Subject: Feasibility of "Whitelisting" and DRM for User-Generated Avatars

Abstract

This paper examines the technical feasibility of implementing "Whitelisting" or Digital Rights Management (DRM) systems within VRChat avatars. Specifically, it analyzes the efficacy of external Open Sound Control (OSC) applications acting as authentication keys, internal PIN systems, and platform-native permissions. The findings indicate that due to the client-side nature of avatar rendering and the lack of logic scripting (Udon) on avatars, true "whitelisting" is technically impossible to secure. The paper concludes that Server-Side Access Control (Private Uploads) remains the only robust method for limiting avatar usage.

Speeding Up VRChat Development: Unity Accelerator Guide

Baking lightmaps and switching platforms between PC and Android (Quest) are the two biggest time-sinks in VRChat creation. Setting up a Unity Accelerator (the modern version of the Cache Server) allows you to offload asset processing and store multiple versions of the same asset simultaneously.

1. Why use a Cache Server for VRChat?

• Instant Platform Swapping: Stop waiting 20 minutes to switch from PC to Quest. The server stores the compressed textures for both.
• Faster Re-imports: If you delete your Library folder to fix a bug, the Accelerator re-populates it in seconds over your local network.
• Multi-PC Sync: If you work with a team or use a desktop and a laptop, you only "process" an asset once; every other machine just downloads the result.

// Mass Book Markdown Downloader for 5etools
//
// This script automatically downloads all books from the 5etools data directory
// as Markdown files. It loads the necessary rendering library, fetches each book's
// data, converts all chapters to Markdown format, and triggers individual file
// downloads. Each book is saved with its original name as a .md file.
//
// Usage: Paste this script into the browser console on books.html
