This may be more of an error when detecting the input when layer blending is being used (as we've seen in other functions), rather than it necessarily being an error with the compilation of the standard material version.

Steps to Reproduce

Download the licensee repro from here - [Link Removed]

Open M_Landscape material

The red section, when connected to the base colour, shows no error.

Connect the "Multiply" node from the green section directly to the Base Colour.

Compiler error will appear: "[SM5] Function MF_Test: Missing function input 'In'"
