@Dwarf_Fever: Its certainly a good idea. though by how the game handles graphics, there are a few problems. First of all smooth walls are directional, while natural walls are not. furthermore, natural walls uses both background and foreground colour while smooth walls uses only foreground, unless engraved.
While your idea is certainly implementable, it requires a few tricks that may come at the cost of readability, especially regarding showing which tiles are designated for digging and which are not. I think the true solution to the discontinuity problem between natural and smooth walls will have to be solved with the new features in the steam release and graphics update. Said update will provide me with an immense amount of work, that may or may not cause me to overhaul all walls, though from the looks of mephs wall suggestion on reddit a few months ago, which paid homage to my wall design, the smooth walls will probably stay the same, allowing me to focus entirely on natural walls.
In an ideal situation, I would want the steam release to forego the top down perspective for a slight isomeric angle, no more than 10°, to show depth of the walls, but that has already been decided against.
Update post and current state of the next update:
I've worked on sprites for wooden furniture, floors and rock blocks. all these will have some additional variation to them in the next update, since the current state only has 1 sprite for wooden table, chair etc. while wooden coffers and cabinets do not differ from stone ones at all. New wooden floor tiles are there to make wooden forts easier on the eyes.
To amend the green colours being to similar, I have decided for all grass and plants to use the light green, while all tree leaves use the darker green. As the tile variance of grass already helps break up the environment, there is no need for different green coloirs for grasses anymore.
I intend to make more sprites for metal furniture but am not sure how to go about it yet. Followers and fans of Mephs tileset may note that he has done different designs for a whole row of different metals and materials. i have not decided wether to do the same and follow his example yet. Until later notice, metal sprites are probably coming sometime during autumn.
To do list:
Wooden Furniture 95/% done
Metal Furniture
- Different sprites for high quality metals?
Bone Furniture (?) - For artifacts
