Render Toolbox is an addon that centralizes rendering setup tasks within Blender. It provides an interface for managing HDRIs, allowing users to quickly adjust rotation, strength, background orientation, and ground levels. The addon includes a light painting feature, enabling artists to place illumination and highlights interactively by painting directly onto 3D models.

For camera management, the tool allows users to create bookmarks that store complete camera transforms and settings without relying on the timeline, alongside a one-click operator to insert keyframes for all active camera parameters. Render Toolbox also integrates post-processing effects directly accessible and previewable in the viewport, including glare, lens distortion, chromatic aberration, film grain, and vignette.
