Avatar & Wearable Submission Guidelines

This document outlines the requirements and best practices for submitting avatars and wearables to OpenPage (:OP:). These guidelines are intended to help creators self-validate their submissions before publishing, reduce compatibility issues, and protect the broader OP ecosystem as it scales.

​
Overview

OpenPage is designed to be an open, creator-first platform. To maintain a safe, legally compliant, and technically compatible environment, certain technical and content constraints must be respected. Following these guidelines helps:
  • Reduce submission issues and delays
  • Avoid post-publication restrictions or removals
  • Maintain long-term compatibility across supported environments

​
Common Submission Issues

​
Avatar Height Requirements

Supported height range: 1 meter – 2 meters (Z-axis) Avatars must be at least 1 meter tall and no taller than 2 meters. Avatars outside this range may:
  • Not load reliably in OP viewers
  • Create compatibility or performance issues
  • Trigger restrictions or removal after submission
Best practices
  • Measure avatar height prior to submission
  • Confirm the Z-axis dimension is between 1m and 2m
  • Use Sideload resizing tools if adjustments are needed
  • Re-export and validate dimensions before publishing
⚠️ Submissions outside the supported height range may be restricted or removed at any time to preserve platform compatibility.

​
Intellectual Property (IP) & Originality

All submissions must use original names, thumbnails, and branding. Not allowed:
  • Using protected or unauthorized IP in names or branding
  • Reusing third-party NFTs, characters, or artwork as thumbnails
  • Implying official affiliation, partnership, or endorsement without authorization
Allowed:
  • Original characters inspired by general aesthetics
  • Parody or stylized inspiration that does not copy protected identity markers
  • Fully custom thumbnails and titles
Creators are responsible for ensuring they have rights or permission to use any referenced material.

​
MML Hosting & Valid URLs

Submissions must include a valid, properly hosted MML URL
(not a direct GLB file link). Common issues:
  • Temporary editor-hosted MML links
  • Links that expire or change ownership
  • Incorrect file type submitted
What to check
  • Confirm URL resolves to an .mml file
  • Ensure hosting is stable and long-term
  • Test links in a logged-out or private browser session
OP is actively exploring creator-friendly hosting options. More guidance will be shared as solutions mature.

​
Platform Content Standards

To maintain a healthy ecosystem, certain types of content are not allowed on OpenPage.

​
Prohibited Content Includes

  • Content that infringes intellectual property rights
  • Stolen or unauthorized digital assets
  • Misleading or impersonation-based content
  • Content that violates applicable laws or regulations
  • Harmful or abusive content, including hate speech or exploitation
  • Spam, malicious links, or deceptive distribution tactics
Creators are encouraged to report content that appears to violate these standards.

​
Potential Platform Actions

If content is found to violate guidelines or platform policies, OpenPage may take actions including:
  • Reducing visibility or feature availability
  • Disabling monetization or transfer-related functionality
  • Removing platform-level discovery or promotion
  • Fully removing or disabling content access
These actions may occur at any time to protect users and the ecosystem.

​
Misleading or Impersonation-Based Content

Content designed to mislead users is not allowed, including:
  • Impersonating brands, creators, or public figures
  • Fake verification indicators or trust signals
  • Content designed to trick users into interacting with malicious links
  • Collections or avatars presented as official when they are not
If content is unofficial or inspired by something external, it should be clearly positioned as original or fan-created.

​
Reporting & Rights Protection

OpenPage respects applicable intellectual property and copyright laws. If you believe content violates your rights, reports should include:
  • Proof of ownership or authorization
  • Clear identification of the content in question
  • Contact information for follow-up
Repeated or intentional infringement may result in broader account-level restrictions.

​
Submission Checklist (TL;DR)

Before submitting, confirm:
  • ✅ Avatar height is between 1m and 2m (Z-axis)
  • ✅ Name and thumbnail are original
  • ✅ MML URL is valid and properly hosted
  • ⚠️ Submissions may be restricted or removed if guidelines are not met

​
Creator Responsibility & Platform Integrity

OpenPage aims to remain open and permissionless and does not act as a proactive gatekeeper for all submissions. Creators are responsible for ensuring their content:
  • Meets these guidelines
  • Does not introduce legal, technical, or ecosystem-wide risk
  • Remains compliant with applicable laws and platform policies
Submission acceptance does not guarantee permanence. Content may be:
  • Restricted
  • Disabled
  • Removed
    if it is later found to violate policies or introduce risk.

​
Why These Guidelines Exist

These guidelines are designed to:
  • Protect creators from unexpected removals
  • Maintain a safe and trusted creator ecosystem
  • Preserve an open, self-regulated creation environment
By optimizing for these constraints upfront, creators help ensure a healthier and more sustainable platform for everyone.
Thank you for building on OpenPage and helping push the edge responsibly.
