Re: Half landing stairs
Actually, now that I think about it, the half-staircase should of course also have separately textured right/left ballusters/handrails. Put the alternatives + errata in SF 3d models 396: with the new staircase_180_landing_00_half_sep_tex.zip.

While I am not convinced it is worth the trouble to change every staircase model to have all options for customisation, it kind of makes sense with the half-staircase - made for use with a landing (just use a box, or a separate Mezzanine level with a floor). The advantage of this, is that it is possible to "build" a lot of different staircases with landings. Even if having every conceivable staircase available for SH3D is unrealistic, this approach and the current standard models, should provide a good range of options.

One problem with this small staircase, is that even if it is imported as a staircase, it will not cut out the floor above until it is raised to ceiling level. To achieve "normal" staircase behaviour, build the staircase with two (or more) half staircases + landing - adjust levels and dimensions - group and import / export as staircase (or use the Furniture Library Editor for the collated model and create a custom cut-out to satisfy the normal headroom requirement over tread: > 200-210 cm.

Using several half staircases in combination may be slightly more complicated, but it is more flexible and also solves the problem that has been annoying me, namely maintaining correct proportions when scaling a turning staircase, i.e.
- angle 17°-42° (30°-36° normal),
- thread depth (going): 30 - 40 cm (> 25) + nosing,
- run/rise ratio (StepRise × 2 + Tread = 62 ±2 cm),
- width curved staircase: > 90 cm (80 cm for straight),
- and so on.

Making staircase models can be quite challenging if you want to ensure basic (not to mention legal) requirements. Many of the SH3D staircase models should be close to generic/prefabricated staircases and generally comply with normal proportions when used in normal scale. Even so, there is no guarantee that the models will satisfy local building requirements. So please do check.
