Installation & Use

Install it like any other addon. After you installed it, go to your blender asset browser and under the drop-down menu you'll find "Floorgen". It contains all assets, materials and generators. Just drag and drop the "Floorgen" generate asset to a plane in your scene to assign the FloorGen modifier. Also drag and drop a FloorGen material and change the settings to your liking.

Using the Presets

Very simple. In your asset browser under "Floorgen", you'll find the "Presets" category. Just select one and drag and drop to your scene.

Using "Append" to edit the assets

The asset browser has the default setting to "pack" or "link" the assets, so to edit the floor meshes, you have to change the import setting to "Append" before you drag and drop.

Export

Just select your floor, go to "File" > "Export" and select your desired export format (like fbx, glb, obj, abc, etc..).
