Common Issues

Textures, rendering, visuals

⛔ Problem: Photo does not display glow or other rendered camera effects, or renders nothing. Or error occurs: “RenderTexture.Create failed: colorFormat & depthStencilFormat cannot both be none”.

✅ Solution 1: Find Scripts → PhotoSettings scriptable object and select the texture format from the list, for example, DefaultHDR for the Glow effect.

✅ Solution 2 (through code): Open PhotoController.cs → MakeScrenshot(). Replace the following line:

targetTexture = RenderTexture.GetTemporary(photoSettings.resWidth, photoSettings.resHeight);

with:

targetTexture = RenderTexture.GetTemporary(photoSettings.resWidth, photoSettings.resHeight, 24, RenderTextureFormat.DefaultHDR);

Or choose another texture format that suits your project. List of all possible formats.

UI, canvas, interface elements

⛔ Problem: Buttons/photos do not respond to input. PhotoController prefab contains its Canvas with UI elements, and existing ones may overlap them or vice versa.

✅ Solution: Unpack prefab and move UICanvas content to existing Canvas or vice versa.

Input system

Both input systems support

⛔ Problem: If you use a new input system, an error may occur: “InvalidOperationException: You are trying to read Input using the UnityEngine…”.

✅ Solution 1: Set inputSystemType → New in the InputController component.

✅ Solution 2: Open Edit → Project Settings → Player → Configuration, and set Active Input Handling to "both".

Demo scene

⛔ Problem: Materials and textures in the test scene are not loading properly.

✅ Solution: All materials & textures for the example objects are stored in the Materials folder. The materials use the "Standard" shader by default. For URP projects, change the shader to "URP/Lit" or any appropriate shader compatible with your render pipeline.

Object Recognition

⛔ Problem: Camera struggles to detect objects accurately, especially when dealing with details or complex meshes.

✅ Solution 1 (recognize one more precisely): Increase the collider trigger of the desired object so that it does not overlap with another and is better recognized. Reduce the Sphere Radius value in the Photo Settings scriptable object. A smaller value results in a thinner ray, making object recognition more precise. Additionally, you can customize the behavior of the RaycastCheck method in the PhotoController.cs to better fit your specific requirements.

✅ Solution 2 (recognize one more precisely): Assign a special layer to interfering objects and disable it for recognition in Raycast Layers in PhotoSettings scriptable object. Or assign a special layer to recognizable object and disable all other layers for recognition.

✅ Solution 3 (recognize all and look for one among them): Use Multiple Objects mode in PhotoSettings, set larger Sphere Radius and multiplayerPrecision values ​​to accurately recognize each visible object. Check if the photo contains the desired object.
