Camera Background is a Blender addon that places background images behind your renders using an automated compositor node setup. It adds backgrounds at four preset scales—100%, 75%, 50%, and 25%—plus custom scaling from 10% to 200%. The intelligent scaling algorithm preserves the complete background at any scale, with no cropping and a maintained aspect ratio.
Lower scale settings speed up preview rendering: 50% renders 4x faster, and 25% renders up to 16x faster, while 100% delivers full-quality output. Background dimensions automatically sync with the render settings. The addon is compatible with K-Cycles Post FX, keeping bloom effects, lens flares, and other post-processing intact. Additional features include shadow catcher support, opacity control from 0 to 100%, and a lock camera to view option for positioning.
The workflow follows three steps: load an image, choose a render scale, then enable and render. The addon uses a clean, non-destructive workflow with full undo/redo support, and it is GPU acceleration compatible. Documentation is included. A demo video is available.
