Well..It looks like just a pattern on overlay I think.
New document

what appears to be around 60x35

use the marquee tool to make that pattern

edit > define pattern

fill with it on a new layer in your sig (in white color)

set that layer on overlay

tadaa IMO

.
Hope it helps.
oh and after overlay, he erased parts it from over the render that didn't look good
