Adding details and creating a concept for a hard surface model can take a lot of time. Sculpting it first and creating a clean mesh afterwards can speed up your workflow but sadly the brushes in Blender have to be adjusted every time you start a hard surface concept.
That's exactly the reason why I created this Hardsurface Brush Pack!
What you get:
6x Different Brushes (+different variations for 5 of them (in total 10 brushes))
1x Sculpt (as seen in the preview)
Created in Blender 2.82
