Decor Attach Blocks for Foundation is a free mod designed for Windows that enhances the building experience in the game Foundation. This mod introduces a collection of height-adjustable blocks, specifically tailored for placing decorations like banners and lanterns with precision. It includes two types of scalable blocks: the standard scalable block and the optimized double scaling variant, catering to different user needs and preferences.

The double scaling block is recommended for its efficiency, minimizing block tiling and reducing strain on the game engine, which helps in maintaining performance even with numerous blocks at greater heights. It features two scaling arrows for precise adjustments, allowing for both coarse and fine tuning of height. The standard scalable block, while easier to use with a single scaling arrow, is less optimized and may lead to lag at higher elevations. This mod thus offers players a choice between ease of use and optimization.
