Vuforia 4.0 Pricing Update

Dear Vuforia Developer,

First, we’d like to thank you for using Vuforia to build such amazing apps!  We are your greatest fans and we take pride in your many accomplishments.  We know that your success drives ours and we want to ensure that we continue to build products that help you grow your business.

With the Vuforia 4.0 release, we introduced new pricing plans that represent a significant change from the past.  We focused on two things:

1.  Making sure that you could develop with the full power of the Vuforia platform at zero cost

2.  Providing deployment options for developers and projects of all sizes

Based on your feedback, we didn’t do as well as we’d hoped.  And we certainly didn’t do a good job of providing advance notice to enable you to plan appropriately. Further, our intent to support a transition through continued support of Vuforia 3.0 did not provide a suitable alternative given Apple’s recent changes.  

On behalf of the entire Vuforia team, I offer my apologies for missing the mark here.

In order to address your concerns, we will be providing an additional pricing option - the Classic plan.  This plan will include unlimited device-based recos for multiple target types including images, multi-targets, cylinders, user-defined targets, frame markers, and text.

We’ll offer the Classic plan for a one-time fee of $499 per app, and it’s available now.  To sign up, please contact the sales team directly.  

We’ll get it on the web site as soon as we can.

Thank you again for your support of Vuforia.  We highly value our relationship with you as developers, colleagues, friends, and business partners.

Hello im getting eror this :( please help me god.


Assets\SamplesResources\SceneAssets\ImageTargets\Scripts\ModelSwap.cs(15,5): error CS0246: The type or namespace name 'TrackableSettings' could not be found (are you missing a using directive or an assembly reference?)


The error usually occurs when there is a mismatch between the Core Sample version and SDK version.

Fixing Vuforia Drift

Hey guys, so I'm trying to make my first AR project with Vuforia. I'm hoping to make it markerless and therefore dependant on GPS but I can't seem to get the world centre mode to work properly. word counter

My two options are:

Use Device Tracking Mode, but this seems to have some drift on the object where if I move my camera around enough it gets displaced from the original location. Is there a way to fix that somehow? Mobdro

Use Camera Tracking Mode (which I think means you just move all the objects around the camera) but I can't seem to find any good examples of this. I move the object but it still stays locked on my screen and isn't really tracked around.

Any suggestions here? Thanks VidMate

Optimized Marker for Tracking

Good Evening,

we're trying to optimize a makeready for a CNC-Machine via Unity for a HoloLens for a studying-project. Therefore we need to place our model as exactly as possible. We're using one image marker (barcode) for the positioning.

So i just have some "little questions" concerning the optimization of precision. I have not really found anything concerning that topic in the net. 

The questions would be the following:

  • Can we use more than one image marker (maybe 4) to center the component of the makeready in the middle of the 4 markers? 
  • Does the use of more than one image marker for one target optimize the precision?
  • Which marker type (Multi-marker / single image marker / object) gives the best values of precision?

It would be nice if anyone could help me.

Thank you very much for your effort!

Best Regards

From experience, I'm gonna guess that multi marker with as many makers possible that are spread out as much as you can while still being visible in the scene would give you the best precision.  I don't have any hard evidence to back this up though.

Thank you very much for these information.


I just have one more question:

I want to try the usage of  more than one image marker (maybe 4) to center the component of the makeready in the middle of the 4 markers.

Image target tracks well but does not detect

I am using a wine label as a marker and it has 5 stars in my target database however it takes a long time to be detected. Once detected it tracks really really well! What could cause this? I have found the only way to make it detect the label is to hold my finger over the camera to make it black and then try again, it usually takes 5-6 goes before it detects.

Hello stevenhadley,

How large is your printed image? Are you placing the image on a wine bottle and curving it at all? How is the lighting on image?

VideoPlayback frozen video on android

I have 10 image targets and 10 different videos attached to it. After I build and deploy the app on an android device all the targets are detected but the video is stuck on first frame or sometimes it plays but on a very low frame rate. I am using the latest version of unity. The app works fine when there are just 2 targets. If more than 3, the same problem occurs.
