In-Camera VFX Aruco Calibration Error

Hi

I followed this Tutorial: https://docs.unrealengine.com/4.27/en-US/WorkingWithMedia/IntegratingMedia/InCameraVFX/AligningYourLEDWall/

Everything works great until I reach step 3.2. As soon as I click on the viewport an errormessage appears with this text:

We could not find an appropriate Aruco dictionary for the selected Calibrator.
Make sure you have selected a Calibrator containing Calibration Point components
with names per the naming convention described in the info section of this algo

I could not find any solution to this. When i open up my icvfx-config and select the calibration points, i can see a list of Aruco points under them. And they have the correct Aruco dictionary names (DICT_6X6_250-1-TL, …)

I also tried different Aruco Dictionaries (250, 1000). I also rebuild the whole setup from scratch, but it ended at the same error message.

Would be great if someone could help.

Hi, i’m exactly in the same situation as you were last November with the Aruco markers . I managed to import an Aruco blueprint , to place it in the viewer but I have the same message you received about the dictionary… since last November have you found the magic solution you could share ?? It would be very very nice because I’m losing my hair day after day.
Thanks !
Stephan

Hey guys, so you have to delete the ndisplay config from the level and readd it because I have no idea but it works
