Euclid Editor is a modeling software which enables you to deform and seamlessly combine multiple 2D illustrations (in PSD format) to render them for a 3D like expression with the original 2D art intact. An Euclid head can be integrated with a 3D body (in FBX format) in Unity, allowing you to take advantage of the 2D expression as well as existing workflow of 3D modeling for 3D games and VR applications.
