Camera rendering freeze

April 9, 2019 - 3:13am #1

I am creating an AR application that uses paintings. In the current prototype there are 4 paintings which work, however, one of the paintings freezes the camera render when A. I lost the mark once and get it back, B. move the camera to the right and/or the below the painting, starting from the center of the image.

I have looked in the unity profiler and the only thing that happens in there is that the batches and setpass calls go up by about 3 per frame. The image and the model rendered on top of the image are both not the ones with the most materials and assets in there, so it is not about the size of those. When removing multiple draw calls, by removing model assets, it still happens.

Does anyone have an idea what could be happening?

Hello,

Strange as that device should have plenty of processing power for such a simple use case.

Do you see the same behavior if you use your device database in our Core samples? If you can reproduce it there, please send me the device database and provide the additional information:

  • Unity Editor version
  • Vuforia Engine SDK version: Unity Editor->Window->Vuforia Configuration
  • Vuforia Core samples version: Unity Editor->Project window: Assets/Vuforia/version

Thanks,

I am using a Samsung Galaxy S8 with android version 8.0.0

Other versions of android phones have the same problem.

Hello,

It looks like camera frames are being dropped while rendering.

What device model are you observing this upon? OS version?

Thanks,
