FAQ

What is the capacity of a MUD room?​

We recommend a maximum of 25 in-room participants. This capacity is the default because low power devices, such as mobile phones and standalone VR headsets, may begin experiencing performance issues in busier rooms. You can adjust the room capacity in the room settings menu.

Once a room is full, all additional users (participant #26 and beyond) can still participate by watching from the lobby. Users in the lobby can see and hear what's happening in the room and interact via text chat; however, they are not represented as avatars in the room and their mic is not active. There is no hard limit on lobby capacity, however, performance may decrease once there are over one hundred people in the lobby.

If you want to scale MUD for a larger event we recommend splitting crowds into multiple rooms with smaller groups, or live streaming the event, depending on the use case.

How long does a MUD room last?​

MUD rooms stay open forever unless you choose the "close room" option from the dropdown menu. Unless a room has been "closed", you will always be able to use the URL to revisit your room. If you plan to revisit a room, you might like to add it to your favorites for easy access.

Can I play video content in MUD?​

MUD has the ability to play videos in the room, which allows you to watch with friends or live stream content from an existing stream. For videos, MUD supports standard video formats. Live stream content is supported in the HLS format. You can embed videos from popular video hosting websites like Vimeo, YouTube, and Twitch, but due to high load these may sometimes be unreliable. For mission-critical content, we recommend hosting videos on the MUD servers by uploading to your MUD room or Creator (there is a 128MB size limit for these videos) or using a hosting provider like Amazon S3.

Where does the chat log go?​

The chat log only exists temporarily. Messages disappear after a set period of time.

Can I share a PowerPoint presentation in MUD?​

MUD is great for giving presentations. Supported media types are PDF files, images, 3D models, audio, video, webcam input, and screen sharing.

To use a PowerPoint in MUD, you can convert it to a PDF file and import it directly into MUD, or you can use screen sharing to stream a view of your presentation into MUD.

Is it possible to have my video or slides show up in a good place (like on a wall) automatically?​

Precise positioning using the object controls in MUD can be a bit tricky at the moment.

If precise positioning is important, you may prefer to build your media into the scene using Creator, MUD's web-based scene editing tool. Creator has controls that let you fine tune object placement.

In the meantime, you may find it easier to resize and place objects when using MUD in VR. If you are setting up a room on desktop, we recommend directly facing the surface you wish to place your media on when importing the files. To move the media into position, you may find you have more control if you click on the object with your mouse to grab it, and then move it into place using the WASD keys.

What devices does MUD run on?​

Because it runs in the browser, MUD is very cross-platform compatible. It works on mobile, desktop, and VR devices, and runs on most modern browsers. For more information check out the supported devices & browsers section.

Why are lines on my drawings disappearing?​

There is a maximum number of lines that can be included in drawings using the pen tool. Once the limit is reached, the first lines will start to disappear. To prevent this, periodically open the object menu on your drawing, and press the "create" button (magic wand). This will turn your drawing into an object, and reset your line count to 0.

Can I create custom environments?​

Environments are completely customizable using Creator, MUD's web-based scene editing tool. Learn more here.

Can I add custom interactive objects to my room?​

Creator allows you to create model spawners in your room, enabling users to generate copies of 3D models in the room.

It is not possible at the moment to add scripting or further interactivity to objects in Creator or MUD.

Can I import 3D models from [other software]?​

MUD supports importing glTF binary (.glb) models. If the tool you use doesn't create .glb files, we recommend using a tool like Blender to convert your model.

Is it possible to create my own avatar?​

For sure! We love seeing custom avatars. You can either re-skin the default avatars or upload your own 3D model (.glb). For more information check out the Creating Custom Avatars section.

Yes, just copy and paste a link for one MUD room into another (or paste the URL into the MUD chat box and press the little cube icon). Due to browser limitations, when you open the new MUD room you have to go through the "enter room" process again.

Can I prevent other people in the room from drawing, controlling slides/videos, etc?​

If you are the room moderator you can turn these on/off by going to scene settings in the dropdown menu.

Is there a laser pointer tool in VR?​

The pen in MUD doubles as a laser pointer tool. When the pen is emitting a laser, you and others will see a line going from your avatar in the direction you are pointing.

How do I fly?​

You can type /fly in the text chat box, or press G on desktop, or press down on the joystick in Quest.
