I'm really bored... so I tried to come up with a way to represent wood, as in lumber already harvested and cut up for use...
I used Grave Peasant model, put on no pathing and used variation 0 and then I used tabled with no pathing stacked on top of each other using Page UP/DOWN to get them look like their stacked.
Heres an idea, take the table model and change the pathing to mushroom and then sinnk the tables into the ground so the surface is the top of the table.
