The Environment: Unity 2022.3.21f1, Mac Pro 2023
Before we begin, let’s take a step back and acknowledge the environment. You’re working with Unity 2022.3.21f1 on a shiny new Mac Pro 2023. It’s essential to consider the specific setup, as it might help pinpoint potential culprits. Take a deep breath, and let’s get started!
Step 1: Verify Image Target Settings
When dealing with Image Targets, it’s crucial to ensure that the settings are correct. Double-check the following:
ImageTarget.name
: Is the name of your Image Target correctly set in the Inspector?ImageTarget.size
: Are the dimensions of your Image Target accurate?ImageTarget.type
: Is the type set to the correct format (e.g., JPG, PNG, etc.)?
Step 2: Inspect the Image Texture
Unity has specific requirements for Image Textures. Make sure:
- The Image Texture is in a Power of 2 size (e.g., 256×256, 512×512, etc.).
- The Image Texture is in a suitable format (e.g., RGBA, RGB, etc.).
- The Image Texture is not compressed (try switching to an uncompressed format like PNG).
Step 3: Check the AR Camera Settings
The AR Camera is responsible for detecting the Image Target. Ensure:
- The AR Camera is enabled and active in your scene.
- The AR Camera’s
Camera.stereoEnabled
is set to false. - The AR Camera’s
CameraTargetFinder.mode
is set toSingleImageTarget
.
Step 4: Validate the Image Target in the Scene
In your scene, check that:
- The Image Target is correctly assigned to the AR Camera’s
targetFinder
. - The Image Target is positioned and scaled correctly in the scene.
- The Image Target is not occluded by other objects or layers.
Step 5: Investigate Device and Platform Settings
Sometimes, the issue lies outside of Unity. On your Mac Pro 2023, ensure:
- The device (e.g., iPhone or iPad) has the necessary permissions for camera access.
- The device is running the correct version of the operating system.
- ARKit or ARCore is supported on your device and platform.
Step 6: Review and Compare with Working Targets
Compare the settings and configurations of the problematic Image Target with a working one:
- Check for differences in the Image Target settings, texture, and material.
- Verify that the working Image Target is correctly assigned to the AR Camera.
- Swap the working and problematic Image Targets to isolate the issue.
Step 7: Test and Debug
It’s time to put your detective hat on and get hands-on with debugging:
- Enable the
Debug.Log
statements in the Image Target script to monitor its behavior. - Use the Unity Editor’s built-in debugging tools (e.g., the Debugger, Console, and SceneHierarchy) to identify potential issues.
- Try testing on a different device or platform to rule out device-specific problems.
Additional Troubleshooting Tips
Still stuck? Here are some additional tips to help you troubleshoot:
- Check the Unity Console for errors or warnings related to the Image Target or AR Camera.
- Verify that the AR Camera and Image Target are correctly configured for the target platform (e.g., iOS or Android).
- Try resetting the Unity project or reinstalling the Unity Hub.
- Reach out to the Unity community, forums, or documentation for further guidance.
Conclusion
By methodically following these steps and verifying your Image Target settings, you should be able to identify and resolve the issue. Remember, troubleshooting is an iterative process, and it may take some trial and error to find the root cause. Don’t be afraid to think outside the box (or in this case, the Unity Editor)! If you’re still struggling, feel free to share more details about your project, and I’ll do my best to help you troubleshoot.
Remember, in the immortal words of Sherlock Holmes: "The world is full of obvious things which nobody by any chance ever observes." Observe, experiment, and debug your way to a working Image Target!

Stay calm, stay patient, and happy debugging! If you have any further questions or need additional guidance, please don’t hesitate to ask.
Frequently Asked Question
Having trouble with your Image Target in Unity? Don’t worry, we’ve got you covered! Check out these common issues and their solutions to get your Image Target working smoothly in your app.
What could be the reason why my Image Target works in Unity preview but not in the app?
One possible reason is that the image target is not properly configured in the Unity scene. Make sure that the image target is correctly set up in the scene, including its size, position, and orientation. Also, ensure that the image target is enabled and has the correct tracker type selected. Additionally, check if the image target is properly linked to a tracker in the scene hierarchy.
Could the issue be due to the Image Target’s lighting conditions?
Yes, that’s possible! Lighting conditions can affect the performance of the Image Target. Ensure that the lighting conditions in the app are similar to those in the Unity preview. If you’re testing in a bright or low-light environment, try adjusting the lighting settings in the app to match the conditions in the Unity preview.
Is it possible that the issue is related to the device’s camera permissions?
Absolutely! Make sure that the app has the necessary camera permissions to access the device’s camera. If the app doesn’t have camera permissions, the Image Target won’t work. Check the app’s settings to ensure that camera permissions are enabled.
Could the problem be due to the Image Target’s size or resolution?
Yes, that’s a possibility! If the Image Target is too small or has a low resolution, it might not be detected by the app. Try increasing the size or resolution of the Image Target to see if that resolves the issue.
Is there a possibility that the issue is specific to the Mac Pro 2023 or Unity 2022.3.21f1?
While it’s possible that the issue is specific to the Mac Pro 2023 or Unity 2022.3.21f1, it’s unlikely. Image Target issues are usually related to configuration, lighting, or device permissions. However, if you’ve checked all the above possibilities and the issue still persists, you might want to try updating Unity or checking for any known issues with the Mac Pro 2023 or Unity 2022.3.21f1.
