Creating an Acrylic-based Brush

A Concepts Brush Tutorial

This tutorial shows you how to combine six acrylic stamps — made from a #4 Filbert Loew-Cornell paintbrush and Mars Black Liquitex acrylic paint — and turn them into your own digital brush to paint with in Concepts.

Creating the Stamp

1 — The first thing I did was imagine what type of brush I wanted to draw with in Concepts. Texture is everything for me as an artist and layering up paints is very satisfying. Acrylics = a great way to go.

May as well do several brushes at once and play.

These are fairly even, with good texture and a bit of variation.

The lighting won’t matter in the end, you just need good contrast. You can also see tiny color differences in the paper grain made from the varying thicknesses of the paper — we want to get rid of these.

A pure white background is the goal, with a good edge to the paint sample. In the end, I decided High Contrast worked best for the first round of filtering, High Key worked best for the second round.

1. Settings -> Artboard Size -> 256 x 256 px. Plain white background. 2. Open Import menu, find the photo, center the paint sample into the artboard. 3. Export to PNG, Custom size. 4. Save image to the photo roll.

Acrylic stamps made from the real thing.

Creating the Brush

1 — Now that I had stamps in hand, I tapped a tool on the wheel and opened up the Brushes menu. I created a new pack called Acrylic Brushes, tapped + New brush, and tapped it again to enter the brush editor.

These stamps will randomly place themselves as you draw the stroke, making for great textural variation along the stroke’s edges.

The stroke on the left (center) is only pressure. The stroke on the right is drawn with tilt and pressure. It’s responsive, fluid, and just how I want it.

Creating the Art

1 — When I feel like drawing but am not sure what to do for the day, I’ll often look on Google Images or my Pinterest boards for inspiration. I paint a lot of characters, creatures and trees, but I decided I was in the mood for something inspiring with good energy — like the mountains I live by, and maybe some trees and a reflection. No matter how many times you draw these, you’ll always get something different, just like Mother Nature.
