Placement Forge

Dressing a level by hand is slow in small, annoying ways. A crate floats a few centimetres off the floor. A barrel sinks into a ramp. Two rocks sit inside each other and nobody notices until a playtest. Placement Forge fixes that by letting the objects collide while you place them.

Physics Move and Rotate

Same handles as Unity's Move and Rotate tools, but the object bumps into things. Push a crate into a wall and it stops there, with a readout showing how far the handle ran ahead. Drag the object itself and it slides along the ground. Hold Space and it drops under gravity; let go and it stays exactly where it is. Rotating a group turns everything around one pivot without anything cutting through a wall.

Arrange and Scatter

Hold Space to push a group of props together until they touch, or spread them apart. Fix overlaps, level a group onto one height, and line things up in rows, grids and rings based on their real size. Array can drop copies into a pile and let physics settle them. Scatter blows a stack apart, heaps loose props into a pile, or nudges a row so it stops looking placed. Every effect plays out in the Scene view, and Esc puts everything back.

Prefab painting

A brush for palettes of prefabs, with spacing, density, slope and height limits, random rotation and scale, and erase, swap and vary modes. Objects sit on the surface whatever their pivot, and "Settle after stroke" drops painted rocks with physics so they rest on the ground instead of hovering over it.

Colliders that fit

Select some meshes and press Generate. Simple shapes get a box, sphere, capsule or cylinder. Everything else gets a collider built from the mesh itself, and tables and arches keep the space under them. Analyse tells you what each object will get and why before anything changes. You can bake colliders straight onto prefab assets, and they are ordinary Unity colliders with no runtime code.

Also included

• Drag a prefab in from the Project window and it lands sitting on the surface.
• Select everything made from the same prefab, of a similar size, or resting on the same floor.
• Audit a scene for duplicates, floating props, strays, missing scripts and empty groups, then fix them.

Your scene's physics is never touched

The simulation runs in a separate hidden scene built from copies of your objects. Only the final positions are written back, so your Rigidbodies stay asleep and your physics settings stay as they are. Objects without colliders still collide. Every action is one undo step, and a recompile or pressing Play in the middle of a drag puts everything back cleanly, including with Domain Reload turned off.

A demo scene, a Quick Start PDF, a full manual, an FAQ and a scripting reference are included. Questions or bugs: [email protected].
