Our office is jam packed with people who studied industrial design in college, so it makes sense that one of our favorite artists, Hudson Rio, is an industrial designer. He’s a master at drawing product prototypes, including some super-sleek cars and some very luscious shoes. We thought hard about how we might create a set of brushes to help industrial designers. The answer came to us pretty quickly: Ask Hudson Rio.

A brush set that’s carefully thought out

We’re delighted to offer up a set of 13 brushes made by Hudson himself. Download Hudson Rio’s Industrial Design Brush Set and use it any time you want to emulate his style. It’s great for drawing strong lines, creamy chrome surfaces, and airbrushed highlights. Even if you don’t draw product prototypes, we’re certain you’ll want to grab this brush set; it’s useful for so many things.

Hudson added opacity markers so you can see more info about each brush at a glance.

Hudson not only made this brush set, he made some beautiful icons for it, which he emblazoned with his initials. For the three brushes and three erasers with different opacity, Hudson added a full, half, and empty circle in the corner to represent the opacity level.

The brushes are listed in the order Hudson uses them for drawing a prototype: from line work to rough sketching, to color blocking, to finishing.

A breakdown of the brushes and how to use them

For the brushes, here’s a brief description of how Hudson uses each one:
  1. Linework Pencil: As the name suggests, this one is for doing very clean line work.
  2. Underlay Pencil: Used for drawing rough sketch underlays.
  3. Ink: This one is for creating an ink look for his line work when that’s what he wants. Because of the large variation in line weight with pressure, this one is also good for shading in solid areas of shadow/highlights.
  4. Shut/Parting Lines: When drawing cars, this one is great for doors, hoods, and body panel lines, as well as for parting lines on product renders.
  5. Soft Shadows/Highlights: Used for soft shadows and highlights. Typically, Hudson says he will shade large areas and erase away (with the airbrush eraser) the over-spray.
  6. Glowing Highlights: Used on a layer (set to “Soft Glow”) above all the other layers. This makes the highlight areas look very bright and adds a lot of contrast to the render.
  7. Full Opacity: Used to block in large areas of color.
  8. Pressure Sensitive: For adding shadows/reflections quickly. Because of the variation in opacity, he can work fast without having to change brushes.
  9. Light Opacity: Used to slowly build up value on a drawing.
  10. Sharp Eraser: This one is similar to the default eraser, but with a sharper edge. Used to erase away color blocks or shadows/highlights to give the surface a glossy appearance.
  11. Pressure Sensitive Eraser: Used to erase away shadows quickly. Perfect for surface reflections.
  12. Light Opacity Eraser: Similar to the Light Opacity brush, this one is used to erase away shadows/reflections without erasing it all at once.
  13. Airbrush Eraser: For erasing away large airbrush areas without giving them a sharp edge. Also used to shape shadows under the cars/products after airbrushing in a general shadow.

More about Hudson

Hudson Rio is a Chicago-based industrial designer who draws gorgeous cars and shoes, and he’s absolutely worth following on Instagram. In fact, he’s almost done with a 365-day challenge. We love seeing what he makes every day.

A few of our favorites from Hudson’s Instagram feed. These brushes are great for industrial design, but they’ll work just fine for characters and figures.
