Value

Control over the strength of the influence of damage. The lower the value, the stronger the damage.

Noise Scale and Noise Detail 
The amount of noise that is applied to the damage. Suitable for different levels of roughness and also for different sizes of objects. Zero parameters for small objects, high for large ones. But it's better to experiment for better results.

Small Damage Scale and Power
Small damage from normal wear and tear throughout the metal. At large scale and strength, the effect of metal corrosion is obtained. With low chipping and damage. I will also add light scratches shortly as one of the stages in the damage.

Gloss, Metal Roughness, Damage Roughness, Rust Normal Power
Standard parameters of any shader. Gloss affects the specularity of the metal, Roughness affects the roughness of the metal. Damage Roughness affects the roughness of the transition between them (rust). Noise power on the damaged part.

Rust Power and Rust Spread
They affect the strength of wear and the strength of rust manifestation.

Based Mode

The strength of the influence of the main parameters from which the damage shader repels

Pointiness Based
The main parameter Pointiness, the higher it is, the stronger the damage repels from the sharpness of the mesh

AO Based
The main AO parameter, the higher it is, the more damage is repelled from the base Ambient Occlusion node

Bevel Based
The main basic parameter for receiving damage in chamfer areas. Mainly used for fine wear on corners.

Bevel Radius
Mainly used at very low settings to achieve a wrinkled effect on the edges.

Bevel Power
Affects the display strength of the chamfer
