This file includes a complete Procedural Stairs Generator created with Geometry Nodes, a ready‑to‑use staircase example with procedural materials applied, and a spiral staircase tower that can be reused or customized for your own projects.You can choose to apply the modifier and export it to any file type via Blender.
The generator offers full control over the structure, spacing, randomness, and deformation of the steps. All parameters are showcased in the demonstration video on the product page: https://youtu.be/so2blP80D0w
Main Parameters:
Stack_Length – Controls the total horizontal length of the staircase.
Stack_Height – Defines the overall vertical height.
Instances_Gap – Adjusts the spacing between steps.
Rand_Min / Rand_Max – Set the range of procedural randomness.
Rand_Seed – Generates unique variations while keeping the same range.
Instance_Number – Controls how many steps are generated.
X / Z – Modify the position or deformation of the steps along the X and Z axes.
Rotation_Effect – Applies a random rotational offset to each step around the Z axis.
Step_Position – Controls the relative placement of each step along the staircase.
Damage_Activator – Enables the procedural damage system.
Effect_Strength 1 / 2 / 3 – Three independent layers controlling damage intensity based on the row of instances.
