Eco Forge – Professional Environment Placement Tools for Unity

Version 1.0 | Editor Extension | (c) Grim Forge – All Rights Reserved

Eco Forge is a comprehensive editor toolset designed to streamline and accelerate the placement of objects within a Unity scene. Developed for level artists, environment designers, and technical artists, it offers five integrated placement methods:

Paint Object – Brush painting with adjustable radius, spacing, Y offset, random rotation, and random scale. Objects snap to any collider surface. Supports grouping and a Bake function to set objects as static and kinematic.

Grid Objects – Create rectangular arrays with user‑defined X,Y,Z dimensions and spacing. The grid preview follows the mouse cursor and can be locked with the P key. Random rotation and scale are fully supported.

Physic Rain – Spawn physics‑enabled objects over time while holding the mouse button. Each object receives a Rigidbody (non‑kinematic, gravity enabled) and an appropriate Collider if missing. Brush size and spacing control the area and density; time interval controls the spawn rate.

Set Physic – Temporarily add Rigidbody components to selected objects and simulate physics in the editor. The tool records which Rigidbodies were originally present and restores original settings or removes added components when simulation ends. Ideal for testing natural settling of piles.

Erase Objects – A smart eraser that deletes only objects created by Eco Forge during the current session, preventing accidental removal of manually placed assets.

Additional capabilities include real‑time semi‑transparent previews, full Undo/Redo support, optional grouping of spawned objects under a timestamped parent, and a Bake function that optimises performance after placement. The tool temporarily overrides Unity’s physics simulation mode to allow Rigidbodies to move in Edit Mode; the original mode is restored when the window is closed.

Eco Forge is ideal for scattering rocks, grass, trees, props, debris, or any environment elements quickly and with full control.
