Custom ImageTarget Doesn't Work

March 29, 2013 - 10:19am #1

Using:

Unity 4.0.1 & Vuforia Unity Extension 2.0.13. 

Steps Taken:

  1. Import Vuforia Unity Package
  2. Delete main camera, add prefab ARC camera, add prefab imagetarget.
  3. Upload image to Target manager, and download resulting unity package. 
  4. Import Unity package downloaded from Target manager, and set the Data set and Image Target in the inspector. 
  5. Under the assets folder create Models and Materials folders. Import FBX into Models folder, and put materials in Materials folder. 
  6. Parent imported geometry to ImageTarget. 
  7. Add a directional light. 
  8. Hit Play and Test within Unity. 

Result: Augmented Reality Fails. 

Observations: I am unable to use any of the Targets uploaded and downloaded from the Target Manager. I tried uploading the standard Stones image to the Target manager (5 stars), downloading the resulting package and setting the data set to the image, but that failed. The only time I can get an ImageTarget to work is when I open one of the Vuforia Unity Sample projects (Imagetargets) and only when using the included targets (stone, chips, tarmac). If I open this sample project, import my imagetargets unity package and switch the data set on the imagetarget plane it fails. 

Why is this happening?

thanks,

Ryan

This is mentioned in the developer guide, here: 

https://developer.vuforia.com/resources/dev-guide/trackable-details-unity

  1. Under ARCamera → Data Set Load Behaviour you should see the Load Data Set field followed by the name of the database that you have imported. Tick the checkbox to enable loading of that database, as well as the checkbox below to activate the dataset at application startup.

Probably, on ARCamera, have you selected load data set "name of your set" and then also selected activat this data set?
