Unity Live Preview on PC is not working (Unity 2018.3.0f2, Wikitude 8.2)



I just removed the default camera and added wikitude camera. When click on Live preview, its showing blank. Please let me know how to address this issue.



I'm using Window 10, but the build setting are for PC.

Did you also add a tracker (image, object, instant) to the scene?

Which Live Preview Mode are you using? For Web Cam mode, you need an external camera connected to the PC. For Remote Camera you need an Android device with Unity Remote connected to the editor.

Are there any errors in the console?

Also, which version of the Wikitude SDK and of Unity are you using?

Thank you,

We're having rendering issues with anything past 2018.1, 2018.2 produces a cropped video image, and 2018.3 produces a black image.

waiting for support for the LWRP in unity >2018.1
the C# support gets shotty in ios with <2018.3, so really hoping for upgrades soon.


On which devices do you have the rendering issues?

Are there any errors printed in the console?

I'm also not sure what you mean with "the C# support gets shotty in ios with <2018.3".

Thank you,


Hi I am having the same issue. I have tried on both internal and external webcams and the live preview crops my webcam off screen. This was occuring on Unity 2018.3.6f1 and I have just now downloaded the latest update from unity (Unity 2018.3.11f1) and the problem still remains. If I use the same webcam on my PC there is no issues, even on the same build of Unity. 

Help would be greatly appreciated since I need this to run from laptop. 

Many thanks,


Hi similar problem here. The live web cam preview is croped and with wrong aspect on my PC. I can use my camera normally with my PC and Vuforia projects.

Thank you
