If there are no feature points in the MREAL space (walls are a single color, no distinctive structures, etc.), camera tracking using spatial features becomes unstable and issues such as misalignment in the display of the 3D CG occurs. In such a case, see “Adding Feature Points” in “Spatial Features” and add feature points to the MREAL space.
Furthermore, if the feature points in the MREAL space have been reduced (e.g., a desk has been removed), clear the map with the following procedure.

1. Cover the front (either the left or right) of the MREAL Display with a hand.

   

   • Cover it until [Lost] appears in the displayed image.

     

   • Do not touch the front surface of the MREAL Display with your hand.

     

2. Look at the Default Marker.

   • When the map is cleared, [Clear] appears in the displayed image. The [Clear] indication will disappear after several seconds.

     

Look at the Default Marker and then move your gaze away from the Default Marker and check that [Lost] disappears.

If [Lost] is displayed even doing the above, clear the map. For the procedure to clear the map, see “Camera Tracking Becomes Unstable when Using Spatial Features”.

[Clear] may appear if you look at the Default Marker after the [Lost] indication has continued to be displayed for a certain period of time. The [Clear] indication will disappear after several seconds.

If the [The amount of the map has \nreached its limit.] message appears, clear the map. For the procedure to clear the map, see “Camera Tracking Becomes Unstable when Using Spatial Features”.

Check whether the host name (or IP address) and port number set by a participant are the same as those in the settings of the organizer's PC.

Check whether MREAL Configuration Server is being blocked by a firewall. Check the settings of the firewall with the following procedure, then take the necessary measure.

1. Select Windows Start menu > [Settings] > [Update & Security] > [Windows Security].

2. Select [Firewall & network protection].

   • Check that [(active)] is displayed in any of [Domain network], [Private network], and [Public network].

3. Select [Allow an app through firewall], and check the [MREAL Configuration Server] setting in the [Allowed apps and features] list.

   • If there is no check mark in [MREAL Configuration Server], place a check mark.
   • Place a check in the item that has [(active)] displayed in step 2 out of [Domain], [Private], and [Public].
   • Click [OK] to close the window.

Check [Display Panel Settings] on the [Display] tab of the Detailed Settings window of the MREAL Display.

• If a check mark is placed in [Video Smoothing Mode], clear the check mark.
• If a check mark is not placed in [Video Smoothing Mode], place a check mark.
• For details on the [Display] tab, see “Configuring Detailed Settings of Basic Settings” in “Configuring Settings in the MREAL Configuration Tool Window”.

When HMD Mirroring Tool is launched, an external monitor for displaying MREAL images must be connected. Connect an external monitor to the PC with the MREAL Display connected.

In the event that the MREAL image does not look three dimensional, the 3D CG is displayed misaligned, the marker images and yellow lines do not match, or another phenomenon occurs, the MREAL image may become easier to see if you perform the following procedure.

1. Prepare a separately sold marker board (MREAL Marker Board [MB-3B]/[MB-4]).

2. Turn on the power of the MREAL Display, and wait for 30 minutes.

3. Launch Camera Check Tool.

   • Click [All apps], and select [Canon MREAL Platform 2025.ｘ] > [MREAL Display Tools].
   • Select [CameraCheckTool_x64] in Explorer.

4. Press button <A> on the MREAL Display.

5. Capture the marker board with the MREAL Display.

   • Hold the MREAL Display with two hands as shown below.

     

   • Capture the marker board from directions (1) to (5).

     
   • Adjust the position of the MREAL Display so that the image of the marker board becomes a size such as the following in the capture screen, then click [Grab] of the Camera Check Tool window to capture an image.

   • Capture at least five images per direction.

     
     
     
     
   • When capturing is finished, click [Check].

6. When the following window appears, click [Close].

   

Performing noise reduction adjustment with the following procedure may solve the problem of the screen flickering when using color masking.

2. Set the noise reduction value in the Detailed Settings window to 0, and place a check mark in [Link Left with Right].

   

3. Register the masking colors again.

   • See “Masking [Other]” in “Color Masking”.
