Vuforia & Unity readpixels error

Question

Hi all,

Past month i've been working with Unity and Vuforia to create an Augmented Reality game for android/tablet. I've been working with a unity-pro trial and since today i've got a full unity pro license. Now i don't know if it has to do with the change from trial to full, but ever since i'm getting the error:

ReadPixels was called to read pixels from system frame buffer, while not inside drawing frame. UnityEngine.Texture2D:ReadPixels(Rect, Int32, Int32, Boolean)

and

Trying to read pixel out of bounds

Leaving me unable to run the game in the editor. It works fine when i build it towards my android or switch platform to pc. But that takes lots of time and i really want to keep bugtesting in the editor instead of building everytime i would like to test something new.

I've tried lots of things already (complete new projects, exporting and importing packages and added a external webcam as well).

(Also: im getting a Webcam profile nog found! error from the WebCamBehaviour script, might have something to do with it)

Thanks in advance,

Tawei

Hi all,

I still haven't managed to fix the errors, but i did find something odd about the editor.

These errors started happening when i switched to a full pro version, from a trial pro version. Yesterday i started my project in another pro-trial and what do you know? The bug disappeared...

So i guess this has something to do with the full pro version, but everything seems up to date. Starting to feel lost in this o.O

Hi,

does this error also happen with the ImageTargets sample app?

Has anyone found a solution to this? I am having the same problem. I had everything working fine with the Unity Pro trial, then my trial expired and everything still worked fine. Then I upgraded to a full (i.e. non-trial) license and I'm getting the readpixels error in play mode. I am able to compile to iOS without issue, but can't test in play mode anymore without receiving the ReadPixels error.

Any help is greatly appreciated I am on a very tight timeline.

Thanks for your help.

This is long gone I know but in my case the problem came from the selected build platform.

As I was building for Android, I selected it but trying to launch back in the Editor and the error comes in. Switch back to PC/Mac and that goes again.

I would guess there is a macro in their code that is not taking care properly of the platform.
