Help

Specifies whether the shader compiler should preserve or unroll flow-control in shader code. This is primarily a debugging aid and will override any per-shader or per-material settings if not left at the default value (0). 0: Off (Default) - Entirely at the discretion of the platform compiler or the specific shader/material. 1: Prefer - Attempt to preserve flow-control. 2: Avoid - Attempt to unroll and flatten flow-control.

Usage

Unreal console (open with ~)
> r.Shaders.FlowControlMode 1

Console variables take a value. Replace 1 with the setting you need. Run it with no value to print the current one.
