Had some time this weekend to get quite a bit done, but the plants and trees will definitely be split to a new hak.
1st pic - 3 different idols or decorations
Next, 3 different pics of some siege machines - catapults, scorpions, rams and towers
Next, a single large mesh of some ruins, a porcelain/pottery shop and a hunter's shack. You can't see it but there are some more hanging skins and some animal carcases on the right side of the shack
Last for now, 2 pics of some placeable bridges - side and top views of 4 different bridges. They can't be walked on of course, but they could be used with scripts or triggers perhaps, plus tileset builders may be able to add them in and add a walkmesh. These are actually twice as high as shown with the rest of the supports sunk into the ground. Also, they could be sunk into the ground completely as possible new road types.
Left out shadows and pwks so they can be walked on, and I think a set with the width set to 50% shown would be more bridge-like, either replacing the ones above or addition to them
Comments and ideas welcome on that or anything else done so far.
