🔍 1. CorePlus AR Debugger
Add the CorePlus AR Debugger component
Set the Debug Type
Create and assign your AR Session Config
🪄 2. CorePlus AR Object Placer

Choose a Placing Type:
Once – spawns only once per session
Infinite – spawns every time the screen is touched
🖼️ 3. CorePlus AR Image Tracking
Add the CorePlus AR Image Tracking component

🛠️ Common Error Fixes
Even with everything set up, you might encounter a few common issues. Here’s how to solve them quickly:
⚫ Issue: Black Screen on Launch
Cause:
The rendering API may not be properly set for your Android project.
Solution:
Go to Project Settings > Platforms > Android > Build
Enable:
“Support OpenGL ES3.2” (or the correct version available)
Disable:
“Support Vulkan”
This ensures that the correct OpenGL context is used for AR rendering, which is crucial for devices that don’t fully support Vulkan in AR sessions.
💡 Tip: Always double-check your Android graphics settings when working with AR in Unreal Engine!
