Need an expression for material in wind >>

Hi everyone,

I am looking for a good expression to use in my material to add RANDOMNESS to the wind.
At the moment all I get is something that looks like its looping the same movement over and over
again.
Any thoughts?
Thank you.
Also what kinda expression is this?
Python? C++?

Its the node description, something like the comment node. The Value part is what you have to worry about. P.S. Custom shaders’ language in unreal depends on the target platforms.

Oh I see … sorry I thought you could enter an expression in there. I come from node based compositing so that looked just like an expression dialogue box to me … Ha! :slight_smile:
