issue with material "missing function input"

Hi all,

I was following Ben Cloward’s tutorial on Rain effect and I have a weird issue,
I get an error on my material function saying that “Missing function input ‘x’” but the input is connected.

I tried adding default values
I tried closing the editor,
nothing worked, what am I doing wrong? is this a known issue maybe?

thanks.

Those inputs are grayed out, so something is likely wrong with them. We’ll probably need to see the inside of that material function, specifically where the rain and roughness inputs are located. The part outside of the function looks fine.

here it is.

I’m a bit baffled about the ‘grayed out’ inputs meaning, for example multiply node also has ‘grayed out’ inputs but it seems that’s because it has a default value.

Okay Roughness was missing inside ‘Wetness’ node…

I’m still new to blueprints I need to get used to it I guess.

SOLVED! :slight_smile:
