Hello,

You are correct in that the VuMark behavior does not behave similarly to other target types.

We strongly recommend that you review our Unity Core samples, free on the Asset Store, for best practices: https://assetstore.unity.com/packages/templates/packs/vuforia-core-samples-99026

Thanks,

Actually my project is built from unity core samples in the asset store. I wanted to know if there is any solution for this from vuforia side. So that the vu-mark gameobject  stays active at all time(On found and on lost).

Hello,

Unfortunately, we've had no luck in determining a simple, app level workaround. The only suggestion we can make at this time is to copy the transform data (position & rotation), and propagate events from the eventHandler to a separate object. This allow you to decouple the augmentation's state from the state of the VuMark game object as thats object's active state is propagated recursively to all its children.

I've been asked by the product team to open a ticket regarding the difference in behavior from other trackables to see if this can be resolved in a future release.

Apologies for not being able to assist more in this matter.

Thanks,
