With the edge-blending method, projector images are stitched together at the edges to form an array. A certain Edge Overlap (typically 5-15%) is applied at the edges to achieve a seamless connection.

• Navigate to the G- Group Controller and switch the Group to "Projection: Lumiverse on". Projectors open the sunshield and start projecting. Remember to switch off at the end of the session.
• Use G- Group Controller to Create a New Project (alternatively, use the default "grid" Project)
• Activate the selected project by clicking on its icon in the G- Group Controller > Projects. The white checkmark appears to confirm the project has been activated.

• Access each projector’s Editor and add the grid containing Media Frame:
  • Enable the "Outlines Forever" function: Settings > Editor Settings > Outlines Forever > enable; working with the Media Frame is easier in this visual mode.
  • Navigate to the Editor
  • Create a grid containing Media Frames in both projectors: Editor > '+' button (bottom-right)
  • If you end up in the last visited folder, click the arrow-up '↑' in the top-left corner to leave the folder
  • Go to the "Light Design" folder > click "Grid.png"
  • Select the grid containing Media Frame, click the 'edit-pencil' button, and click "Fit to Screen" to ensure the grid spans the entire available screen.

• Align all grid-containing Media Frames across all Editors to form an array with some edge overlap. You can organize projectors into rows, columns, or rectangles. Tetris-like shapes are not supported. We recommend an edge overlap of around 5-15%.
  • Use corner dragging to adjust the perspective deformation of the grid containing Media Frames in each projector’s Editor, forming a perfect rectangle with 90-degree angles and precise edge alignment.
  • Use Editor > select Frame > 'edit-pencil' > "Precise Mapping Tool" to select individual corners, then align them with high precision using the 'arrow' buttons.
  • Align the edges of the Media Frames; create overlapping areas along neighbouring edges that will later become soft-edge blends.
  • Make sure both the vertical and horizontal lines of the grids are perfectly parallel. Make sure that vertical lines are precisely real-world vertical, and horizontal lines are precisely real-world horizontal. Being very precise at this stage will yield a perfect image blend.
  • When done, use Editor > 'edit-pencil' > 'lock' symbol to lock the object’s corners in place. 
  • Note: If you want to generate a pixelmap (recommended for complex geometrically rich objects, such as buildings, not necessary for plain walls), don’t use the Mesh Warp or Bezier Warp for these adjustments; they are not pixelmap compatible. The Bezier Warp is designed to adjust flat video for plain curved and spherical surfaces.

• We recommend changing Media Frame's source to a plain solid color to make the following steps easier to distinguish visually. However, this is not mandatory; you can still complete edge blending with other media in the Frame, but aligning visual lines will be harder as they would be less visible.
  • Recommended: select the grid containing Media Frame, select 'edit-pencil' > "Change Source" > "Light Design" folder > "Blue Br.png".
  • Repeat for every projector.

• Add the Multicanvas Filter onto all Media Frames that you want to connect with edge-blending. This Filter will take over the Media Frame's Transformations and render the edge-blending soft masks over the content. This will result in a seamless connection between edge-blended media frames.
  • Navigate to the Editor
  • Select the Media Frame and click 'edit-pencil'
  • In the top right corner, click the 'filters' tab
  • Click '+' to add a new filter, select "Multicanvas Filter"
  • Repeat for all projectors/Media-Frames that you're blending together.

• Connect the Media Frames
  • Navigate to Editor > select Frame > 'edit-pencil'
  • In the top right corner, click the 'filters' tab, open the Multicanvas Filter sub-menu 'three-dots' (⋯), and select 'edit-pencil'.
  • This is where you control the Multicanvas Filter.
  • Click "Topology" and click the '+' button to create a New Topology. Topology is like a connected group of media frames projected from different projectors.
  • Fill in the new topology name and confirm by clicking the "Create" button.
  • Now, open another tab in your browser and navigate to the other projector/media-frame that you want to connect to this topology.
  • In the other projector, navigate to Editor > select Frame > 'edit-pencil'
  • In the top right corner, click the 'filters' tab, open the Multicanvas Filter sub-menu 'three-dots' (⋯), and select 'edit-pencil'.
  • Connect the projector to the newly created topology. Click "Topology". Topology selection opens. Select the topology you just created in the other projector and connect to it.
  • A matrix of (+) buttons will show around the device's ID number. Select the appropriate (+) button so that the projectors' relative physical position matches the visualized scheme.
  • The next step is called Edge Overlap; here, you control how much the media frames overlap at the connecting edge. This is set separately in each Media Frame's Multicanvas Filter.
  • Navigate to the Multicanvas Filter, click the "Edge Overlap". There's a slider that controls the position of a black line, rendered in the projection.
  • Swipe the "Edge Overlap" slider (alternatively use '+' and '-' buttons for small steps) to align the position of the black line with the neighbouring Media Frame's white edge.
  • The white line edge of the neighbor projector should be exactly in the middle of the Edge Overlap's black line.

• • If the black-and-white lines are not parallel, switch back to Editor and adjust the Media Frame corners to fine-tune the alignment.
  • Repeat for all projectors.
  • In the Multi-Canvas Filter, find the "Mode" option, click the "adjustment" dropdown button, and select "Mode: blending". As a result, the black lines and projector ID numbers hide; the media frames now show a soft-edge blend.
  • Navigate to each projector, Settings > Editor Settings > Outlines Forever, and turn off "Outlines Forever" to hide the Media Frame white outlines in the projection.
  • Use the Gamma slider in the Multicanvas Filter to fine-tune the brightness gradient of the edge blend.

• Test the edge-blended Media Frames with various content.
  • Navigate back to the Editor in all projectors.
  • Select the Media Frame, click 'edit-pencil', and click the "Change Source" button.
  • Navigate to the "Light Design" folder, select "Grid.png"
  • Repeat for all projectors
  • Switch off at the end of the session: Navigate to the G- Group Controller > Power Button (top-right) > switch "Projection" off
