Description

User report:
I want to run iOS shaders with half precision floats as I do on Android. If I disable Force 32 bits Floating Point Precision, there are unfortunately a bunch of shader compilation errors. I’ve tested on vanilla UE5.3.2 just to be sure there wasn't a conflict with our source code and the problem is exactly the same.

Steps to Reproduce
  • Run UE5.3.2.
  • Disable Force 32 bits Floating Point Precision in Project settings.
  • Restart.
  • Load FPS test level.
  • Run iOS package creation in Development mode.

Have Comments or More Details?
