Shader breaks and throws an invalid GBufferFragOutput to FragmentOutput type cast error after switching Render Path to Deferred

Hello. It is correct that this is a problem, but unfortunately we are not able to fix this. Even if it was possible to do so, we cannot back-port changes to deprecated functions, as it might break shaders for users who have already fixed the issue themselves.

Steps to reproduce:

Open the attached project
Open the Sample Scene
Observe how the bush object is rendered, as well as the errors thrown in the console window

Actual results: Shader throws a type conversion error and does not compile

Expected results: Shader compiles and visuals match compared to when using forward rendering

Reproducible with versions: 6000.2.0b1, 6000.3.10f1, 6000.4.0b8, 6000.5.0a8

Not reproducible with versions: 6000.0.68f1, 6000.2.0a10

Tested on (OS): macOS 26.3, Windows 11

Notes:

The issue only occurs when using Deferred/Deferred+ rendering paths
