Got it. I’ll search for VRChat world prefabs—likely hosted on Booth.pm or GitHub—that automatically capture and display in-world photos using render textures. I’ll prioritize ones used in multiple worlds, especially those that show 4–8 ephemeral images visible to everyone in the instance. I’ll also include similar alternatives you might find useful.

VRChat Automatic Photo-Capture Prefab (Ride Photo System)

Identifying the Prefab: PhotoBoard by AniBox (Booth.pm)

The description you provided matches a free VRChat world prefab called “PhotoBoard”. This prefab is an automatic photo-capture gimmick for VRChat worldsbooth.pm. It was released on Booth.pm (a Japanese asset marketplace) by the creator AniBox in January 2024booth.pm. The PhotoBoard prefab automatically takes pictures of players at certain moments during the world experience and displays those photos on a board, much like the “ride photo” systems in theme parks. The Booth.pm page (written in Japanese) explains that “it automatically takes a photo centered on you at unexpected moments and displays it”booth.pm – which fits the behavior you described.

Features of the PhotoBoard Prefab

PhotoBoard comes configured to show 8 photos by defaultbooth.pm, aligning with your memory of 4–8 pictures being displayed. When a player is in the world, the PhotoBoard’s script periodically triggers a virtual camera to capture an image of that player’s avatar. The system uses ephemeral render textures for these images, meaning the photos exist only in the running instance of the world (they are not permanently saved or uploaded anywhere). All players have the prefab active locally, so each person’s PhotoBoard captures their own viewpoint (their avatar’s face is centered in the shots) and displays those shots on the board for thembooth.pm. In practice, world creators often time these automatic shots to coincide with key locations or moments – for example, a particularly exciting spot on a ride – so it feels like a location-triggered “ride photo”. The captured images show up on the in-world photo board in real time. Because the photo capture is handled client-side (locally), the content of the photos isn’t network-synchronized across playersbooth.pm. This means each player sees their own set of photos on the board. (In other words, if you and a friend ride together, each of you will see photos of yourselves on your own screen, rather than a single shared photo. This might not be obvious in-game, and to the user it just appears that “everyone can see the photos being taken,” since each person sees a photo appear on the board at the right time.) By default, the PhotoBoard takes the first picture ~10 seconds after activation and then continues at a set interval (e.g. every 30 seconds, adjustable)booth.pm – world authors can tweak this timing or trigger it via Udon events to suit their world’s design. The result is a fun gimmick where players are “surprised” by automatic snapshots that are displayed at, say, the end of the ride or in a clubhouse, creating a memorable highlight of the experience.

Other VRChat Photo-Capture Solutions

Since you expressed interest in similar tools, here are a few related prefabs and systems in the VRChat community that deal with in-world photos:

• Fairplex’s Polaroid Camera (Booth) – A Polaroid-style camera prefab for VRChat worldsbooth.pm. This is a pickup object that players can use to manually take photos and “print” them as physical Polaroid pictures in the world. It works on both PC and Quest (world-only, not for avatars) and allows multiple snapshots; as of version 1.9, it supports up to 20 photos by default stored on the camera’s boardbooth.pm. World creators can place this Polaroid camera in their world to let players snap photos at will. (Unlike PhotoBoard’s automatic timed shots, this requires the user to actively take a photo, but it similarly produces in-world images that other players can pick up or view.)
• Oikki’s Online Photo Board (Booth) – A more advanced (paid) world gimmick that acts as an online photo bulletin boardbooth.pm. This system lets players in the world take a snapshot (using the VRChat camera) and post it to a shared board in the world, where it will persist across instances. The photos (small thumbnail images, e.g. 64×64 px) are uploaded to an external server so that even if everyone leaves, the images remain for the next visitorsbooth.pm. There are moderation features (an admin can approve images before they show for others, etc.) to prevent abusebooth.pm. This is different from PhotoBoard in that it permanently saves and syncs the images for all users, functioning like a community gallery in the world. It’s a great option if a world creator wants players’ pictures to stay on display, but it does require allowing untrusted URLs (since it pulls images from the internet) and using a dedicated server.
• Photoboio Instant Camera (Gumroad) – This is an avatar-attached camera gadget rather than a world prefab, but it’s worth mentioning for completeness. Sold on Gumroad (not on Booth), the Photoboio Instant Camera is an avatar accessory that lets you take Polaroid-like instant photos wherever you go. It can print and save up to 6 photos on the spot as physical photo propsnote.com. Users can shake the camera to eject a film “cartridge” and have fun with a realistic Polaroid workflow. Because it’s an avatar item, it works in any world and even allows friends to press the shutter for younote.com. Many VRChat photographers found this useful before VRChat implemented its own photo printer feature for VRC+ users. (Keep in mind that this is attached to avatars via a system like VRCFury, not something you’d drop into a world for all to use.) Each of these solutions has a different use-case and feature set. For your needs – a world-based automatic photo capture system that displays a set of ride-like snapshots – PhotoBoard is the clear match to what you described. You can download it for free from Booth.pmbooth.pmbooth.pm and integrate it into your world. Its Japanese documentation outlines the setup, but in summary you just import the unitypackage and drop the PhotoBoard.prefab into your scenebooth.pm. By adjusting its settings or combining it with Udon triggers, you can have it take photos at the exact moments or locations you want, giving your VRChat world visitors a delightful “photo souvenir” experience similar to what you’ve seen in those other worlds.Sources: The details above are referenced from the Booth.pm product page for PhotoBoardbooth.pmbooth.pm, which confirms its automatic photo-taking and 8-picture display, as well as update notes and community articles discussing similar photography gimmicks in VRChatbooth.pmbooth.pmnote.com. These should help you verify that PhotoBoard is indeed the prefab you were looking for, and give you leads on other interesting photo systems in VRChat. Good luck with your world building!
