Different Types of Assets

Smart Modules

Smart Modules are like layers with all sort of imperfections and details that you can add to new or existing materials (pbr or procedural).

Shaders

Shaders are simple and light nodes to use as your material starting point.
(You can always use other materials from the library or pbr materials as a starting point too)

Textures

Texture Modules are procedural layers that add details in the normal of the materials.

Masks

Masks are used as complements to use in modules that have mask inputs or special modules like Material Mixer.
