Every first-time installation of Clip Studio Paint involves an excited exploration of the Decoration subtool. It's a veritable smorgasbord of natural, unnatural and downright goofy brushes that can quickly generate rock-encrusted wastelands, dense forests or, more likely, just a random smear of black and white.
In my experience, this toolset quickly gets relegated to the digital equivalent of the bottom drawer. There is, however, a way to fix this, turning it from a little-loved tool into an absolutely essential time saver.
01. Start with a simple silhouette(opens in new tab)
Think about creating silhouettes: using your own custom-made brush tips is key here. A variety of leaves (hand-drawn or scanned and traced) combined can look like a dense bocage, a set of random blobs add up to the intergalactic power of comics legend Jack Kirby's 'Kirby Krackle' effect and a crowd is really just a mass shape composed of numerous individuals. Each brush tip should be made of a simple silhouette.
Draw a variety of shapes on a single layer in black and white, then select them individually and add to the brush list using 'Edit > Register Image as Material'.
02. Build on an existing brush
It's always easier to start from an existing brush and build up. So find a Decoration subtool you think might do the job – most of my more successful silhouette brushes are derived from the Foliage brush – and use the Create Copy of Currently Selected Sub Tool icon to duplicate it and then edit it.
03. Organise your brushes
Once you've designed a few of your own more useful decorative brushes, you can drag them out of their subtool and on to the toolbar on their own, grouping them together to save time hunting for them when you need them.
You can produce a complex silhouette by waving the brush around and applying pressure to help generate random patterns.
