Setting the ARCamera's Target Texture to a unity Render Texture it seems to make it angry. after the unity splash screen i can exit and enter the application to see a still image of whatever the camera is viewing. Is Render to texture supposed to or going to be supported.
thanks for your help
Render to Texture isn't currently supported. QCAR renders the camera background natively, and so it won't be part of the final texture. If you add a Render Texture to the ARCamera you should get the augmentation, but the buffer won't be cleared each frame. Feel free to add this to the http://ar.qualcomm.at/node/2001256. - Kim
sorry to bring back such an old thread, but is "Render to Texture" still unsupported?
I still have problems with it, described here: https://developer.vuforia.com/forum/general-discussion/how-use-unity-render-textures-vuforia
The Render to Texture has some limitations with AR Camera, as described in this article:
https://developer.vuforia.com/resources/dev-guide/unity-screenshots
Hello, I'm trying to capture the final image generated by Vuforia using a RenderTexture for best performance. I can do it with ReadPixels but it is just too slow.
The link you mentioned seems out-of-date, as the current BackgroundTextureAccess sample does not contain the elements described by the dev guide. The sample only shows how to capture the background image using a Texture2D. For now, I can only capture the video as a Texture2D this way and capture the 3D objects as another RenderTexture associated with ARCamera (with a black background).
What can I do to render both the background video image and 3D objects onto the same RenderTexture?
Thank you.

Have you had any problems building out to a device using this method? It works perfectly in the simulator but when built out to Android or iOS, I see a black screen instead of the background camera's render texture. The augment does become visible when either device is pointed at the marker, however, it is over a black screen. Furthermore, the augment is not clearing off of the screen at the end of each frame, resulting in an anomaly which looks like a deck of cards being pushed out on a table.
Been working on this one for some time now and this is the closest I've gotten it to display properly on a mobile device.
