New Release 7.5 Patch (SDK 7.5.26)

Today we’re launching a patch to Vuforia Engine 7.5 (7.5.26) which includes some critical fixes:

• For Model Targets, we’ve made several improvements to augmentation performance
• For Unity developers, we fixed an issue related to EULA acceptance
• For iOS developers, we fixed an issue that would sometimes cause ARKit apps to crash on launch

Currently available for download via the Vuforia Developer Portal and via upgrade directly in Unity 2018.2. See Release Notes for details.

 

Hi, I'm using Xcode 10.0, Vuforia 7.5.26 & Unity 2018.3.x (BETA). When I build the app it works fine in iPhone but it crashes in iPad Pro.

App works fine if I build it in Unity 2018.2.x.

here is my crash log

How to fix this issue?

 

So I'm developing a project using image target and I'm using the version 7.5.26. The problem is that when I run on unity editor mode it works fine, but when I build an Android .apk the app open but the image tracking is not working. I'm using a development key, I don't know if that if that is an issue. I can't find an answer, all the configuration is just like the Vuforia sample.

 

Hello,

Always print the image that was uploaded to the portal to the exact same aspect ratio. Any stretching or altering of the image will cause it not to be detected. Some printers default to "stretch to fit", which can change the aspect ratio.

Thanks,
Vuforia Engine Support
