AutoShader - Effects Toolkit for Aseprite

💡 Instant Light & Shadow for Pixel Art

AutoShader adds professional highlights and shadows to any sprite — with an interactive light source you drag in real time and a live preview that updates as you tweak. All without leaving Aseprite.

No more painting shadows pixel by pixel. No more guessing where the light hits.
