It does say a bit: > "the backgrounds are digitally hand-painted and the texture on the characters is crafted to get that graphical look that fits with the environment. We also mainly use 2D animation for the FXs (explosions, tears, smoke...) to reinforce the painted look" The animation style reminds me in a way to Spiderman - Into the Spiderverse style of animation, but with a totally different tone/style (Arcane being more "rough"/handpainted, flat and darker). Specially the battle scenes have a very similar composition between Spiderverse and Arcane, though again with its differences (Spiderverse seems more Japanese-like animation on steroids, while Arcane is more handpainted style).
