For Model Target Generator installs after July 28, 2018, please use the new Model Target Generator v7.2.24.
Dynamically Loading and Activating Datasets
With the launch of Model Targets and its restriction of only a single Model Target dataset being activated at a time, we have seen an increase in the number of questions related to loading and activating datasets programmatically.
Model Target FAQ and Common Issues
The following is a set of common issues and questions that have come up related to the new Model Targets feature. I'd also recommend that you read through the Model Target documentation found here: https://library.vuforia.com/features/objects/model-targets.html
Model Target Crash
I'm new in AR and I'm testing Model Target functionality.
I created the dataset from Model Target Generator and imported it into Android Studio. The Guide Views are displayed correctly in the app, and the model is tracked correctly.
The problem is the crash of the app in the moment of rendering of my model. I have an "OutOfMemoryError" exception. I tried with 3D object with .obj and .v3d extension, but I have the same problems.
Next, the details of the error:
Model Target won't lost track in iOS
Using iOS version, the UI and model didn't fade out when the object is lost track. It works fine in Unity Editor and Andriod Platform.Please advise.
The following is environment details:
Unity 2019.2.14f1 (64-bit)
iPad Pro(12.9-inch)(3rd generation) Software Version 13.3.1
Model Target Generator 8.6.7
I download the package from vuforia developer portal.
Freeze rotation Model Target
I use Model Target, that's work well. But I want to freeze the rotation of my asset. If I turn my object I don't want that my asset turn.
So I wrote a little script :
private void Start()
MTx = MT.transform.rotation.x;
MTy = MT.transform.rotation.y;
MTz = MT.transform.rotation.z;
Quaternion rotation = Quaternion.Euler(MTx-MTx, MTy-MTy, MTz-MTz);
Model Target Generator
I have 3 generated model targets and I want to create a database to train all 3 of them, but when I am about to add them, I can choose only one despite the fact that they are in the list (but their choice box is grayed out). Any solution, somebody please? Thank you.
ModelTarget issues with Hololens demo
I just downloaded the demo from here: https://assetstore.unity.com/packages/templates/packs/vuforia-hololens-1-2-sample-101553
It seems to be fairly recent and I'm trying to access how and how well do model targets work on Hololens.
Based on this demo, I just changed the Mars model by our own test model (which we also have in reality), used the default HLL1 config in MixedRealityToolkit (like we do in our projects with success) but run into some issues:
