Timber Panels - Housewrap question

[dunny1234]

I've built a few timber frame panels today, including OSB sheathing. I had a delivery of 'housewrap', but it didnt have any branding/logos on it, and i'm a little unsure what side faces out?

Theres a shiny side, and one side has a kind of raised pattern on it. I know it's important to get it right.

Any help, would be great!

I know i sound stupid, and maybe i am, but both side appear shiney.

Side A. is like the top of a waffle with miniture pits

Side B. is flat

(Images below)

I'm still not sure what side faces out?

Sorry to be a pain, but any help means sleep for me tonight, thanks

Please help!!!!!
