I can share my version of the town wallset if you want to use it, but it needs some normal maps to be complete, and I don't know how to do them correctly.
Of course if you want to have normal maps everywhere. But for the most, I use the normal from the asset pack.
I 've removed most of the things, included the animated door and all doors. Except the normal maps, the pack is about 3,1 mb. Note that I've done that to reduce drasticaly the wallset, and because I did not need or like the rest of it.
The town looks like castle style, but to be used with a height level of 3. The pillars, doors and arch comes from castle stuff and are resized to fit the correct height.
I use the castle stairs with this, and have keep some of the low wall and quartersize pillar, with a marble texture.
There is also some kind of wood wall (with the mine pillars or not), that I use like an "inside-of-a-ship", simple 2d model with the town wood generic texture.
I don't know if all things are good, maybe some experienced ppl can have a look, and say if it is or not a bad result. I ve try to make something as similar of the asset pack, anyway it's a final version for me, as I don't use normal maps to save ressources.
About the occluders: I don't use any for the marble walls, they are always on the 2nd stairs and are defined as "base_wall_decoration" without replacing any wall.
For the stone and wood walls, ground or ceiling, I use the occluders from the asset pack.
here is some previews:
The doors here, are fake.
About the mine wallset, I do not see the need to do that, the log2 mine tileset is much better. So why do you want this one?
The only things that can be useful, are the wagon, rails, smoker and volcano.
