Prerequisites

1. Screen obj
2. MPCDI file (read more below)
3. Pixera 1.8.325 or later

If multiple devices are used → Director Client Setup

Setup

Scalable Export Options

On the Export Options screen, you will select the MPCDI 2D, 3D or Shader Lamps option for
Scalable Display Manager and the Shader Lamps option for outputting the correct files from Atlas:


 

Screens

1. Import Screen model into PIXERA
2. In the case of scalable, scalable-specific settings can already be applied to the import options
   Set X Rotation to 180 degrees
   (Optional for some objects, this setting will invert the V axis of the UV map) Check Invert V. 
   If needed, set X/Y/Z scale factors to convert to the correct size units, this is usual the value 0.001 on x,y,z.
   
   
   
   
    
3. Position 3D model in scene
   
   
   
   
    
4. Define Canvas Resolution, Screen position, Role in Venue as “Screen” and Selective Target Rendering as "Texture per Screen"
   
   
   
   
    

Mapping

1.  Select the projector used in the setup, or if not available, use a "Generic Projector".
   In the case of a Generic Projector, this resolution should be specified.
    
2. Assign the Output → Read more
    
3. Deactivate the checkbox "Automatic Projector to Screen Mapping Creation" to prevent the projector positions in the 3d workspace from being misaligned when loading the MPCDI calibration (Make sure that selection mode is set to projectors when selecting the projectors). Repeat this step for all projectors.
   
   
   
   

   Warning

   Not all feed modes work with all MPCDI formats, if the format is set to SL only "None (Original Screen Object)" works, this is not the case with others, as the warp is not available. Read more about Feed Areas
   
   

    
   
    
4. Make sure selection is set to “Screens” and select the Screen Object
   
   
    
5. Load the MPCDI Files and assign it to the Projectors
   1. 1. Select “Load Calibration”
   2. 2. Select the path of the MPCDI file
   3. 3. Assign the region to the individual projectors
   4. 4. Set “Unit Scale Factor” (typically 0.001)
   5. 5. Apply Changes
   6. 6. Close the Window
      
       
6. After this step, the positions of the projectors in the 3d workspace are adjusted. In compositing, content that is matched to the UV map of the 3d object can now be played correctly. To do this, assign it to the screen (3d object) and place it on the timeline. With different resolutions of screen object and UV map, it can happen that the scale unit mode of the layer has to be changed→Scale Unit Mode

Compositing

In compositing, content that is matched to the UV map of the 3d object can now be played correctly. To do this, assign it to the screen (3d object) and place it on the timeline. With different resolutions of screen object and UV map, it can happen that the scale unit mode of the layer has to be changed→Scale Unit Mode

After a test pattern or content, which has been fitted to the UV map, has been placed on the 3d object, you can recognize it in the preview. If these textures are not applied correctly, the texture coordinates may need to be inverted or the canvas resolution may need to be adjusted. In most cases this corresponds to the resolution of the test pattern with which the UV map was created.
