June 30, 2020 - 7:32am #1

Hi, I have been using model target with much success, however, i couldnt interact with the model. The idea is to touch the model and it renders appears along with another image. I have tried this with a simple cube in an empty scene, however it doesn't work model generated by the vuforia engine. 

the code is as follow:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

How to enable and disable guideview through button

June 30, 2020 - 3:27am #1

Hi all! I'm trying to implement a button to show a guideview of a model target, basically when the button is pressed a script attached to the model target with a function is called. The function is: 

public void GuideView()


        modelTargetBehaviour.GuideViewMode = ModelTargetBehaviour.GuideViewDisplayMode.GuideView2D;


Actually nothing is appearing on the screen, could it be that the canvas is hiding the guideview? Is there any solution?

thanks to all

Also, when the  "New Game Object" instantiates, which has the ModelTargetBehaviour script attached. On clicking the object in the hierarchy the following error occurs. Image attached:
