# 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 for a proper Blender addon in the future.
