float16_t is not working properly with DXC on DX12
Reproduction steps:
1. Open the attached “Float16Test.zip“ project
2. Open the “Assets/Outdoors.unity“ Scene
3. Enter the Play Mode
4. Observe the Game View
Expected result: The cube on the left is red and the cube on the right is green
Actual result: The cube on the left is black
Reproducible with: 2021.3.34f1, 2022.3.18f1, 2023.2.7f1, 2023.3.0b4
Reproducible on: M1 MacOS 14.2, Windows 10 (22H2)
Not reproducible on: No other environment tested
Note:
- Using the 2021.3.34f1 the cube's on the left shader is red, but it is shifted to the right (it’s behind the green cube instead of next to it). Similar behaviour is seen on all of the versions using M1 MacOS
- The issue is only reproducible when using the DX12 Graphics API
