Camera view upside down when adding shader to a camera

Question

When I have a shader on a camera (main camera or ar camera) the camera image flips upside down. Is there a way to fix this? Is anyone else having this problem? (only on android / iOS, not on desktop btw).

Answer 1

Most probably it is happening because of platform specific UV coordinates. You will need to modify the shader to flip UV coordinates on mobile devices using #if UNITY_UV_STARTS_AT_TOP

You can find more info in the Unity manual https://docs.unity3d.com/Manual/SL-PlatformDifferences.html

The shader is orientated correctly, because it also shades the other elements under the unity camera (like the interfaces & other 3d objects). So only the camera image flips. Not everything under the shader.

If it is happening only when using a custom shader on the camera, it is a shader issue.
EasyAR 3 is using CommandBuffer to render camera feed and using its own custom shaders, everything else is rendered in a separate pass so is not influenced by the shader.
