I really love the almost bejeweled, or galaxy infused watercolour designs of Caomor (@caomor) who I follow on Twitter, so I wanted to try and replicate a similar look on a simple model. Oddish was both extremely cute and simple enough to try this out in an afternoon Original artwork viewable here: https://twitter.com/caomor/status/1049494055518908416
Made in Zbrush, matcap texture was handpainted in Photoshop, and renders were done in Zbrush with a small amount of post effects added in After Effects to simulated a blotchy animated watercoloury look to appear less static. Zbrush does have render options for these types of effects however I'm not aware that you can actually animate them as procedural screenspace effects. Would be awesome if you can/could!
