Easy Decal provides you with an easy-to-use workflow for putting decals on all types of surfaces in your game world. Enrich your virtual world with details and lift your game environment to the next level.
Easy Decal not only supports diffuse textures and normal maps, but all kinds of shaders and materials. You can stick decals even to massively bumpy surfaces with ease – the dynamic geometry generator automatically adjusts all the necessary parameters (UVs, tangents, normals, etc.) in the blink of an eye. By using one tool, your decals will fit everywhere.
