A shiny reset button made of nickel for your high tech project.
Geometry: Quads only.
Diameter: 1.5 cm.
Model consists of two objects: button base and (as a child object) button itself; proper local motion constraint set for button to limit its motion against base.
Material: purely procedural PBR Nickel, color value referenced by PBR Rendering Encyclopedia; material based on Principled shader thus widely compatible with modern PBR renderers.
UV maps unwrapped.
HDRi environment map (Blue Grotto, public domain) packed in .blend for more realistic reflections, as well as put into supporting items separately.
All imagery is done via Cycles / Filmic (Base Contrast profile), no post-processing. Please note, that anything else except button in this description used in product imagery, was for demonstration purposes only, and not included in the package.
