Thank you all for your posts.
Much to killing my hope, I guess their isn't something raw but rather gm basis.
This raised from the argument at one of the tables I play where the gm straight said that a tent or anything of a fabric material used as an obstruction was enough to stop daggers and bolts from going through till the fabric was destroyed - not anytime before.
They made an even farther out case wherein a paper wall would at least absorb the first attack aimed at a creature on the other side; regardless of concealment or cover bonuses, the paper wall would tank a heavy crossbow bolt before allowing you to get off a proper shot that wouldn't be glanced/deflected/eaten by the paper - that's if the paper was destroyed on the attack.
I decided to use "a wooden wall" in this case to cut through that ridiculousness and see if a raw feat/ruling/class-feature was available to shooting through something. I could definitely take my GMs argument and wait till brilliant energy becomes available, or abuse his wording and carry expandable fabric walls in my inventory but I think I'll try to find something else to play that will avoid trying to make my case again.
Thank you all again, you've been most helpful
