A little late for Halloween, I know. Let’s just say it’s really early instead. 😛
Required: Floors-N-Walls (free)
Info: DAZ Studio only duf format; I haven’t gotten around to making any other material files. The textures for the Floors-N-Walls are all image map based though, so Poser users could add these textures manually.
There are a bunch of mix-n-match presets for the wall, panel, floor, and trim. Some are purely Halloween-related, others more neutral. There are plain wood and plain plaster presets, including “tintable” options.
Edited to add: These are basic DS default materials. They’re very simple and should convert fine to iray, ubersurface, or other shaders of choice.
Usage: Okay for personal and commercial renders.
Bonus texture; no image maps just tiling so this one is DS only. You’ll need the free Kamelian Wall Megapack.
Also, for a little extra variety you can add this architectural detail prop to the Floors-N-Walls:
It’s free; download it here: Base and Crown Molding
It’s not texture-map friendly because of the scaling requirements but it looks pretty good with just plain old diffuse coloring.
