David Lettier mainly uses Blender in his workflow. If you want to learn from the artist, check out his collection of shading techniques, in which he explains each technique step-by-step using the example of the Panda3D game engine and the OpenGL Shading Language; the artist also breaks down how to apply the techniques to other engines, such as Unreal Engine, Godot, or Unity.
Previously, we featured Lettier’s take on the coat worn by Howl from Studio Ghibli’s Howl’s Moving Castle, a magical sphere, Hollow Knight: Silksong fan art – a recreation of Hornet, painterly Christmas cards, a hand-painted-style lamp, and more. Have a look at them below and find more on the artist’s X/Twitter:
