CleanMaterialBuilder is a tool specifically designed for creating clean materials. The default Unity material creation process (creating a default material first and then selecting a Shader) often leads to redundant properties, particularly unused texture attributes, which can inflate the size of AssetBundles.

CleanMaterialBuilder uses a workflow where you select the Shader first before creating a material, resulting in materials with no unnecessary properties. Additionally, it features a prefix tag filter that displays only Shaders with specific prefix tags, preventing artists from accidentally using unrelated Shaders and simplifying the Shader selection interface.

Additionally, to avoid redundant data caused by artists changing a material's Shader, the tool includes a built-in material cleanup function. Users can batch-select materials or clean all materials in the entire Assets folder at once, ensuring the final APK maintains a minimal data footprint.
