OneDeck is a workflow optimization add-on built specifically for environment artists, consolidating numerous custom tools into a single universal search menu. By relying on a dedicated hotkey system, it provides immediate access to object controls, allowing users to adjust lighting, array settings, or scattering parameters without navigating through standard interface panels.

The toolset includes specialized utilities for scene assembly and environment generation. Features include linear and circular array generators, physics-based asset placement, surface snapping, and interactive drawing for curves and primitive meshes. Additionally, the add-on provides dedicated generators for creating roads, procedural noise terrains, volumetric fog, and simulated growth patterns for elements like ivy. It also includes workflow utilities for launching the asset browser in a new window, setting up instant HDRI shaders from local files, and generating project folder structures.
