Decal Shader

Add realistic decals to any weapon, prop, car or environment object with minimal setup. Decal Shader is a flexible and performance-friendly solution that allows developers to quickly apply high-quality decals without the complexity of traditional decal systems.

This package adds decal functionality to the Standard Lit Material. Its main advantage over traditional decals is that it performs projection along a single axis and avoids additional draw calls, resulting in better performance.

In addition, since the decal shader is integrated with the main Lit shader, it can reuse the textures of the underlying object. This allows for more realistic results. Its only disadvantage is that, since it samples along a single axis, it can only be used on flat surfaces. For example, you would not use it on the corner of a wall. If you do, texture stretching will occur.

If you do not want to use a material-based decal shader, that's fine. The package also includes a separate decal shader that can be used with decal objects. However, it does not support the features listed below. In addition to the Base Color and Normal inputs provided by Unity's default shader, it adds Metallic/Smoothness inputs and color tinting parameters.
