wooden box detecting?

hey there,

I was wondering if anyone would be willing to share information on how they detect wooden boxes?
I've thought about a possible option of editing the game files to show wooden boxes as infinitely tall, so you could spot them anywhere.. is that even possible?

if there is another method, and you would like to share it with me, i would very much appreciate it.

If there is a paid method, I am willing to pay.

Thank you very much!
