Hi guys,
being new to the environment I am currently trying to setup the most basic vuforia application, by displaying a 3D object above a picture I have laying around using my webcam.
I run the 2020.3.15f2 unity version on my windows 10 Laptop and included the 10.0 Vuforia plugin. My laptop is a commercial Dell machine from like 2013 or so, but seems to be running smoothly. Since it doenst have a builtin webcam I bought a noname camera which I recently replaced by a Logitech C270 HD Webcam.
Besides watching a bunch of tutorials about unity in general I was trying to complete the steps presented in either of the below tutorials:
- https://www.youtube.com/watch?v=yECYjgx5Byw&ab_channel=devloopAR
- https://www.youtube.com/watch?v=WdfStRynCLw&ab_channel=ElectronicandTime-BasedArtPurdueUniversity
Both have the exact same outcome. The screen turns black (unless I change the colour under "Background" in the inspector. And an Error Message is displayed (see Screenshots). Unfortunately I am unable to take much from that message, other than believing that this error causes the problem.
I did reinstall and reboot everything but consistently get the same result. Even with the different webcam. With all tutorials I have watched, it should simply start playing the webcam when hitting play. The webcams are working fine and not being used by any other devices. The branded webcam for some reason shows up as "USB Video Device" under the Camera Device name. This caused me to alter the webcamprofilex.xml file in order to remove a previously existing webcam profile error.
I havent yet found anyone with similar errors and don't know how to go from there. I have rebuilt and reimported the entire project multiple times. This unity visualisation is a small puzzlepiece to a larger existing project including MQTT. Just thought I'd mention that as "callback" functions are part of that protocol.
I'd be grateful for any clues regarding where to start on this,
Jonas
Hey there,
Hey there,
Since you mentioned it's a very basic Vuforia project, would you be able to share it as an attachment?
Many thanks!

Great, thanks Jonas! I will go through the project and let you know as soon as possible if I find anything.
Hey Jonas,
Hey Jonas,
Hi again,
Hi again,
Very grateful for your suggestion and I did get it working with Unity 2019.4.29f1 and Vuforia 9.8.5.
Full story:
1. 2019 with vuforia 10 created the identical problem as I had initially.
Hey Jonas,
Hey Jonas,
I am very glad to hear that the 9.8 works for you, but I will continue to do internal research why this did not work for 10.0.
Would you be able to provide your system specifications? That might help our R&D to find out the issue.
Hi Patrick,
Hi Patrick,
here you go. Its an really old Laptop, but performance rarely lets me down. Possible that there are other limitations,
Thanks
Hey Jonas,
Hey Jonas,
Would you be able to try Vuforia Engine v10 and Unity 2020 and provide me with the full error message? Our R&D wanted to take a deeper look at what error is being produced.
Many thanks!
Kind regards,
Patrick Scheper
Sorry to interrupt but I had
Sorry to interrupt but I had the same error with SDK 10.0 with Unity version 2020.3.10f1 and 2021.1.4f1.
The full error message is shown as this.
Hey there,
Hey there,
No need to be sorry!
@jonaskreiner, it would be good if you can share/validate if you get the same issue.
@hanss1, are you also using an external webcam? If so, would be great if you can share the type.
Many thanks!
