This is my formula for procedural wooden pallets, for geometry nodes.

With it, you can adjust various parameters of size, width, height and gap between the boards in a column, on a wooden pallet.

It's perfect for creating assets for games or archviz.

The modifier result comes without materials and without mapping for now, the colors in the example are illustrative.

However, I left a default model, with the modifier applied, mapped and textured, with two materials to choose from.
