Myself and the developer of the popular Less Building Placement Restrictions mod discovered a problem with Tier 3 corner stair pieces. It may be tied to the size of their collision boxes seemingly exceeding that of the lower tier corner stairs.
While the Sandstone and Stonebrick stair corners can be snapped into place when trying to “round off” stairs that extend into the ground, the higher tier corner stairs (Khitan, Black Ice, Reinforced Stone, Insulated Wood) do not. Instead, only the long, bottom edge of the stair will snap to anything else. This leaves the small, upper-most portion of the corner stair either underneath an existing stair, or sticking out in the open.
From what the developer of NBPR can see, “Stonebrick and Sandstone share the same dimensions in both it’s collision box and asset. All the rest are different (slightly larger). Since they are larger, they have larger collision boxes, which means when you try to rotate, they colide, which causes them to “skip” over a rotation.”
For more info, and a video demonstration of the issue, here is the discussion thread from the Steam Workshop:
NOTE: This happens even with no mods installed whatsoever!
Steps on how to reproduce issue:
- Place a square foundation on the ground or a slope so that it protrudes high enough to need stairs.
- Place full-width stairs extending into the ground along all 4 sides of the foundation.
- Attempt to place corner-stairs into the diagonal gaps.
- You should observe that Sandstone and Stonebrick snap into place whereas the higher-tier corners don’t.
