If you have questions that are not being  covered here, join our discord and let us know.

Material issues

“Everything is pink in Unity, why is this?”

You probably set up a Universal Render Pipeline (URP) project. If that's the case, you need to convert the materials as the demo scene is built with the Standard Render Pipeline.  

Open your Project in Unity, and go to Edit > Render Pipeline > Universal Render Pipeline and select either Upgrade Project Materials to URP Materials or Upgrade Selected Materials to URP Materials

“When I build my project everything disappears, help me!”

This still might be due to setting up the project on a URP template. 

Open your Project in Unity, and go to Edit > Render Pipeline > Universal Render Pipeline and select either Upgrade Project Materials to URP Materials or Upgrade Selected Materials to URP Materials

Then go to Edit >Project Settings > Graphics and  in Scriptable Render Pipeline Settings select Universal Render Pipeline

Snapzones

“Why is my snapzone not highlighting in the built application?”

Most probably the model does not allow read/write. To fix this, select the model of the object in your project assets folder and open the Unity Inspector. In the model's properties, you'll find a "Read/Write" checkbox. Set it to true.

Tracking issues

“The “hands”/ controllers  seem to be stuck in the ground. What’s happening?”

First, we would recommend you to check that your controllers work outside of the Unity environment, also check if your headset is tracking correctly as it could be an issue not related to VR Builder or Unity.
If this is correct, please check for the correct controller profile on XRIT/OpenXR. 

Testing applications

“My standalone application is not working, now what?”

Check the set-up tutorial to make sure you’ve followed the VR Builder setup instructions correctly. Specifically XR settings such as OpenXR/Oculus  setup.
