We have a project with Unity4.6.3 and Vuforia 3-0-7 cloud based application. Now we are going to upgrade the project with Unity5.1.1f1 and Vuforia 4-2-3.
Our application has multiple tracker images on cloud. Once tracker image detected, its relavent data will download from our own web-server and displayed on tracker.
I have created a new Unity5.1.1f1 project and imported vuforia-video4-2-3 package.
When am integrating... facing some issues.
i have imported CloudRecoEventHandler and content manager scripts from old project.
On Start, we are getting clould access key and secretkeys from web-services. once access key received, we are enabled the CloudRecoEventHandler.cs script.This gives an error "Null Referense" at mObjectTracker.TargetFinder.ClearTrackables(false); .
public void OnStateChanged(bool scanning)
// clear all known trackables
If i comment the above
mObjectTracker.TargetFinder.ClearTrackables(false); line, something working. Most of the times augmentation is not working.
If i delete the ARCamera and again if i add, Augmentation is working. Is there any problem with Vuforia4-2-3 and Unity5.1.1f1 ?
We are very urgent to upgrade the project but we are facing these type of problems and getting struct.
Please help, how to resolve the null referense issue at mObjectTracker.TargetFinder.ClearTrackables(false); .
and ARCamera issue ?
