Thick Sprite Mesh

Thick Sprite Mesh add the third dimension (depth) to your sprites - no 3D modeling skills needed!

This simple Unity plugin lets you transform any 2D sprite into a thick customizable 3D object with just a few clicks, while maintaining the sprite's original charm, and offering flexibility in design and appearance.
