AI image generators are a powerful tool for Roblox creators, allowing you to design unique textures for clothing, detailed decals for your games, and eye-catching icons. However, many creators run into a frustrating roadblock: asset rejection. Your carefully prompted image gets denied by Roblox moderation, often with a generic reason.
While Roblox's moderation process can seem opaque, there are common patterns in AI-generated art that tend to trigger rejections. By understanding these pitfalls, you can adjust your prompts and editing process to greatly increase your chances of approval.
Problem: Unintelligible or Garbled Text
AI image generators are notoriously bad at creating readable text. They often produce imagery that looks like letters but is actually meaningless gibberish. From a moderation perspective, this is a major red flag.
Why it gets rejected: Moderation systems can't read the 'text,' so they can't verify that it doesn't contain inappropriate language, slurs, or personal information. To be safe, the system often rejects any asset with text-like symbols it cannot parse.
How to fix it:
- Prompt for no text: Add phrases like 'no text,' 'textless,' or 'no writing' to your negative prompts.
- Edit it out: If an otherwise perfect image has garbled text, use an image editor to remove or paint over that section before uploading.
- Add text manually: Generate the image without text, then add your own clean, readable text using an image editor.
Problem: Excessive Photorealism
While impressive, highly realistic images of people, objects, and places can run afoul of Roblox's style guidelines and safety policies, especially when it comes to faces and real-world locations.
Why it gets rejected: Roblox aims to maintain a distinct, non-realistic art style. Photorealistic faces can be mistaken for images of real people, which is a privacy and safety concern. Similarly, realistic depictions of logos, brands, or locations can create intellectual property issues.
How to fix it:
- Use stylistic prompts: Add terms like 'cartoon,' 'anime style,' 'stylized,' 'cel-shaded,' or 'low-poly' to your prompts to guide the AI away from realism.
- Avoid real names: Do not include names of real people, brands, or specific places in your prompts.
- Focus on concepts: Prompt for 'a heroic knight' instead of 'a photorealistic portrait of Henry Cavill as a knight.'
Problem: Hidden or Unclear Details
AI art can sometimes contain strange artifacts, merged objects, or abstract patterns that are visually confusing. What looks like a random swirl to you might be flagged as something inappropriate by an automated moderation system.
Why it gets rejected: If the moderation system cannot clearly identify every part of an image, it may err on the side of caution and reject it. Ambiguous shapes can be misinterpreted as violating community standards.
How to fix it:
- Review carefully: Before uploading, zoom in and scrutinize your image for any weird or ambiguous details. Look at it from a distance and squint. Does any part of it look like something it's not supposed to be?
- Clean it up: Use an image editor to remove or clarify any confusing elements. If a shadow looks odd or two objects have merged strangely, paint over the area to simplify it.
- Increase 'guidance' or 'CFG scale': In some AI tools, a higher guidance scale can lead to more coherent and less abstract images, reducing artifacts.
Problem: Mimicking Copyrighted Styles Too Closely
You might ask an AI to generate an image 'in the style of Disney' or 'like a Pokémon character.' While this is a great way to get a specific aesthetic, it can lead to rejections based on intellectual property (IP) concerns.
Why it gets rejected: If your asset looks too much like a character or design from a well-known brand, Roblox's systems may reject it to avoid potential copyright or trademark infringement issues.
How to fix it:
- Describe the style, don't name it: Instead of 'in the style of Pokémon,' try 'Japanese anime style, cute creature, bold outlines, bright colors.' This prompts for the artistic elements without using the trademarked name.
- Combine styles: Mix and match descriptors to create a more unique look, such as 'cel-shaded cartoon style with watercolor backgrounds.'
Frequently Asked Questions
My asset was approved but is now deleted. Why?
Moderation can happen at any time. An asset might pass the initial automated review but be flagged later by a user report or a manual review. This is common if the asset is a borderline case.
I see other people with similar assets. Why was mine rejected?
Moderation is not always perfectly consistent. Another creator's asset might have slipped through, or it might be different enough to not trigger the same flags. Focus on making your own assets as compliant as possible, rather than comparing them to others.
Can I appeal a moderation decision?
Yes, Roblox has a process for appealing moderation actions. However, for assets, it is often faster and easier to edit the image based on the likely reasons above and try re-uploading it.
Key Takeaways
- Avoid generating images with text. If you need text, add it manually with an editor.
- Steer clear of photorealism. Use stylistic prompts to create art that fits the Roblox aesthetic.
- Thoroughly inspect your images for ambiguous shapes or artifacts before uploading.
- Describe the artistic elements of a style instead of using copyrighted brand names in your prompts.
- When in doubt, simplify your image to make it as clear and unambiguous as possible for moderation.
