# Heavyjan 10 Projection Mapping As part of my effort to combine 3D and 2D in my work, I developed a projection mapping shader that enables me to project my 2D paintings and reuse elements with very little effort. [...]

No UV mapping is required. You can see the original painting at the very bottom of this page. With this workflow I can do overpaints of existing 3D scenes, create 3D scenes from 2D paintings and enhance 2D paintings with 3D effects. I can add lights that cast proper shadows, adjust the perspective, reuse projected assets in other scenes and so much more. I might expand this toolset into a proper Blender add-on in the future.
