I wanted to share a personal pack of procedural materials that I use to previs my hard-surface designs when working in Blender. Materials are grouped and can be easily called into the node editor from the group tab. Materials have changeable colour and other input values such as scale and detail of different normal and strength of bump details.
All materials were designed with PBR workflow in mind and all have respective Color, Roughness, Metallic, Normal output values, some materials support displacement too. MeshVoid procedural pack for Blender includes 39 materials and Mask Generator Node with 19 different output masks for you to stack and mix any base shaders you want on your model. Materials that require UV to function have UV signature on them.
