A fully procedural Floor Generator built with Geometry Nodes, designed to create realistic and customizable stone pavements with clean, production‑ready results.
The file includes the generator with its modifier already set up, along with a preview mesh that showcases the system using the included procedural material. This allows you to inspect the output immediately and fine‑tune the parameters to match your environment.

The generator is ideal for architectural visualization, ruins, fantasy environments, dungeons, and any scene requiring modular, natural‑looking stone flooring.
All controls are exposed, intuitive, and optimized for both beginners and advanced users.

Compatible with Blender 4.5.

• Floor Generator (Geometry Nodes setup)

• Preview mesh with the procedural material applied

• Stack Length – Defines the total length of the floor. Integer values recommended.

• Stack Width – Sets the width on the secondary axis. Integer values recommended.

• Floor_Height – Controls the height of each stone instance.

• Instances Gap – Adjusts the spacing between individual stone blocks.

• Instance_Length – Manages the length of each instance along one axis.

• Rand Min / Rand Max – Minimum and maximum range for random block dimensions.

• Instance Number – Controls the number of blocks; recommended values between 1 and 2.

• X / Z Scale – Scales each instance along the X and Z axes.

• Rotation Effect – Adds subtle random rotation on the Z axis for natural variation.

• Damage Activator – Enables or disables procedural stone decay.

• Effect Strength (3 values) – Controls decay intensity for different block groups (editable directly in the GN panel).
