06 Unreal Engine for Architects Staircase Steps Calculations

Session 6 Summary: Stairs for All Floors

• Project Setup:

  • Continued from previous session's project apartment_05 stairs completed.

  • Saved new level as apartment_set5_06_all_stairs_completed.

• Planning and Calculations:

  • For floors with a height of 3 meters, recalculated step height to 20 cm (previous was 14 cm).

  • Maintained a step width of 100 cm and depth of 26 cm.

  • Each staircase segment has 5 steps and 3 segments per floor.

• Stairs Creation:

  • Used dynamic floating stairs in modeling mode.

  • Created parapet walls using edge loop insertion and push/pull tools.

  • Set parapet wall thickness to 10.16 cm (4 inches) and height to 90 cm (3 feet).

  • Adjusted parapet walls to appear flat using vertex alignment.

• Stair Placement:

  • Created 3 segments per floor using the Pattern tool on the Z-axis.

  • Positioned them around the elevator: left, back, and right sides.

  • Precisely adjusted gaps and overlaps using polygroup edit and push/pull operations.

• Mesh Consolidation:

  • Combined the three stair parts using Boolean Union.

  • Renamed the result as sm_stairs_ground.

  • Converted the dynamic mesh to static mesh and unwrapped UVs by poly groups.

  • Assigned pillar concrete material.

• Repetition for Upper Floors:

  • Duplicated the finalized stair mesh using Pattern for two additional floors (1st and 2nd).

  • Renamed them accordingly:

    • sm_stairs_first_floor

    • sm_stairs_second_floor

• Organization:

  • Grouped all stairs into a Stairs folder in the outliner.

  • Saved all changes in project and Unreal content browser.

• Conclusion:

  • Staircases for all four floors (stilt + 3 floors) are now complete.

  • Ready to begin interior modeling in the next session.
