How to Use Battle Maps on Owlbear Rodeo for D&D Sessions

Quick Answer: Owlbear Rodeo is a browser-based VTT with no required player accounts. You create a room, upload a map image, configure the grid, add tokens, and share a link. The full setup for a single encounter map takes under ten minutes once you know the workflow. This guide covers every step in sequence.

Owlbear Rodeo 2.0 is the fastest path from a map file to a live session of any VTT currently available. Where Roll20 requires account creation from every player and Foundry requires a license and local hosting, Owlbear Rodeo asks for nothing from players except a browser and a link. That frictionless entry point makes it the right choice for one-shots, new groups, and DMs who want to spend prep time on the game rather than the software.

This guide walks through the complete workflow for setting up and running a battle map session on Owlbear Rodeo. Each step is covered in sequence, from opening the platform for the first time through sharing the session with your players.

Step 1: Create a Room

Navigate to owlbear.rodeo in any modern browser. On the homepage, click Create Room. Owlbear Rodeo creates a private room and takes you directly into it. No account required for this step if you are using the free tier.

Once inside the room, you will see a blank grey canvas, a toolbar on the left side of the screen, and a menu bar along the top. The room link is visible in your browser address bar. This is the link you will share with players later. You can also find it by clicking the people icon in the top toolbar.

If you create a free account on Owlbear Rodeo (optional but recommended for ongoing campaigns), your rooms persist between sessions. Without an account, rooms are temporary and will not be available the next time you open the platform.

Step 2: Add a Scene and Upload Your Map

Owlbear Rodeo organizes content into scenes. Each scene holds one map and its associated tokens, fog of war settings, and grid configuration. You can have multiple scenes in a room, one per encounter map, and switch between them during a session.

Creating a New Scene

Click the Scenes icon in the left toolbar (it looks like a stack of layers). In the scenes panel, click Add Scene. Give the scene a name that identifies the encounter (for example, "Tavern Brawl" or "Dungeon Level 1"). Click Create. The new scene opens as a blank canvas.

Uploading the Map Image

Click the Assets icon in the left toolbar (the image icon). In the assets panel, click Upload and select your map image file. Owlbear Rodeo accepts JPG and PNG files. Once uploaded, the map appears in your assets library.

To place the map on the scene, drag the image from the assets panel onto the canvas. The image appears on the map layer by default, which is correct. Do not drag it to the token layer. The map layer sits behind tokens and fog of war so the stacking order works correctly.

Once placed, click the map image to select it. Use the resize handles at the corners to scale it. Do not resize by eye at this stage. The next step (grid configuration) will determine the correct size for you.

Step 3: Configure the Grid

Grid configuration is the most technically important step and the one most new Owlbear Rodeo users rush or skip. Getting this right means every map you import after it will align correctly without repeated adjustment.

Opening Scene Settings

Click the Scene Settings icon (the gear icon) or right-click the canvas and select Edit Scene. The scene settings panel opens on the right side of the screen.

Setting Grid Type and Size

Under the Grid section, set Grid Type to Square for standard D&D play. Set Grid Measurement to Feet and Cell Size to 5 feet (one square equals five feet).

The critical field is Grid Size (also labeled as pixels per cell in some versions). This value tells Owlbear Rodeo how many pixels wide one grid square is in your map image. For maps built at the industry standard of 140 px/sq, enter 140. For maps built at 100 px/sq, enter 100. This value is documented in the product listing of any professionally produced map pack.

If you do not know the px/sq value of your map, divide the image width in pixels by the number of columns of squares on the map. A 4200-pixel-wide map with 30 columns is 140 px/sq.

Aligning the Grid Overlay

After setting the grid size, Owlbear Rodeo overlays its grid on the canvas. Zoom in on the map and check whether the overlay lines sit on the map's printed grid lines. If they are offset, use the Grid Offset X and Grid Offset Y fields in scene settings to shift the overlay horizontally and vertically until the lines align. Adjust in small increments. Once aligned at one intersection, the grid should align across the whole map.

"Set the px/sq value correctly once and every map built to the same standard will align on the first try. It is the one configuration step worth getting exactly right."

Step 4: Add and Configure Tokens

Tokens in Owlbear Rodeo are images placed on the token layer that represent player characters, NPCs, and enemies on the map. Any image file can be used as a token.

Uploading Token Images

Go back to the Assets panel and upload your token images the same way you uploaded the map. Token images work best as square PNG files with transparent backgrounds. Standard size recommendations are 280x280 pixels at minimum for a crisp display. Many DMs use circular crop tokens with transparent backgrounds so the grid is visible around the token edges.

Placing Tokens on the Map

Drag a token image from the assets panel onto the canvas. Owlbear Rodeo places it on the token layer automatically. Click the token to select it. In the token settings panel that appears on the right, set the Grid Size field to match the creature size: 1x1 for Small and Medium creatures, 2x2 for Large, 3x3 for Huge. The token will snap to the correct grid footprint.

Naming Tokens and Setting Visibility

Click a token and use the name field in the token settings to label it. Player character tokens should be named to match the characters. Enemy tokens can be labeled generically (Goblin 1, Goblin 2) or left unnamed if you prefer not to telegraph enemy identities.

To hide a token from players, click it and toggle Visible to Players off in the token settings. Hidden tokens appear with a strikethrough eye icon to the DM but are invisible to players. Use this to stage enemy positions before revealing them at the start of combat.

Assigning Token Control to Players

In the token settings panel, find the Attachment or Owned By field and assign each player character token to the corresponding player's name. Players can only move tokens assigned to them. Tokens with no assigned owner can be moved by the DM only. Set enemy tokens to DM-only control to prevent players from accidentally moving them.

Step 5: Set Up Fog of War

Fog of war hides unexplored areas of the map from players and reveals them as the party explores. It is one of the highest-value features for interior encounter maps and worth the five minutes of setup it requires.

Enabling Fog of War

In the Scene Settings panel, find the Fog of War toggle and turn it on. The entire map immediately becomes hidden with a dark overlay visible to both the DM and players. As the DM, you see the map beneath the fog. Players see only solid darkness until areas are revealed.

Revealing Areas

Select the Fog of War tool from the left toolbar. You will see two options: Reveal and Hide. Click Reveal and draw over the areas of the map that players can see at session start. Owlbear Rodeo uses a brush-style tool. You can adjust the brush size for rough reveals over large open areas or precise reveals for narrow corridors.

To hide an area you have already revealed (if players retreat, or if a door they passed through should no longer be visible), select Hide and draw over the area. The fog returns. For most sessions, you will only use Reveal, progressively uncovering the map as the party moves forward.

Pre-Revealing the Starting Area

Before players join, reveal the area where the session begins. Players should see the starting location as soon as they enter the room. Revealing nothing and asking players to navigate a completely dark map creates confusion. Reveal at minimum the room or area where the first scene takes place, and reveal adjacent areas as the party moves into them during play.

Step 6: Share the Room with Players

Click the People icon at the top of the screen. Owlbear Rodeo displays your room link and an invite code. Share either the link or the code with your players via Discord, text, or whatever your group uses.

When players click the link, they are prompted to enter a display name. They do not need an Owlbear Rodeo account. After entering their name they land directly in the room, see the scene you have set up, and can move any tokens assigned to them.

As the DM, you can see all players in the room from the People panel and control what each player can see or interact with. Players who join before you have revealed fog of war will see only the areas you have already uncovered.

How Do You Switch Between Maps Mid-Session?

Open the Scenes panel and click the scene you want to switch to. The canvas updates immediately on your screen. To send players to the new scene, right-click the scene in the panel and select Broadcast Scene (or the equivalent option in your version). All connected players are moved to the new scene simultaneously.

Tokens, fog of war settings, and grid configuration from the previous scene are preserved when you switch. When you return to that scene later in the session, everything is exactly where you left it. Setting up all your encounter scenes before the session starts means mid-session transitions take under five seconds.
