This is a very low primlow walkways set in Maldivian atoll style , with alternate poles and dense wooden bars floor , its fully sculpted and so it uses some megaprims to increase the lod level and make the sculpt mantain its look even by far , for this the grabbing position of the itemis slight offsetted from its center .

Looks great, but ...
... a little hard to place the objects. Also the parts itself are phantom and come with an invisible object to walk on, so you have to move 2 objects at once, which means you can't use EDIT to set positions. However, once you went through that hassle, you will have a great designed walkway!
