- Working with MegaWorld Window — how to navigate the window
Step 1 — Open the MegaWorld Window and select Pin
Press Alt + Z to open the MegaWorld Window. In the Tools Panel, click the + button and choose Pin from the Happy Artist group.Step 2 — Set up your Group and prototypes
In the Selection Panel, create or select a Group and add the prototypes you want to place. Pin picks a random prototype from the selected ones each time you click.Step 3 — Click to pin an object
Click on a surface in the Scene View. MegaWorld places a preview object at the hit point. The object starts at scale(0, 0, 0) and is ready for you to shape it.
Step 4 — Drag to rotate and scale
While holding the mouse button:- Move the mouse in a circle around the click point to rotate the object.
- Drag the mouse away from the click point to scale the object up.
- Drag toward the click point to scale it back down.
Step 5 — Release to confirm
Release the mouse button to commit the placement. If you release without dragging (cursor stayed within 5 pixels of the click point), the object is discarded.Step 6 — Adjust Transform Mode
Open Pin Tool Settings in the inspector to control how rotation and scale respond to the drag:- Set Rotation → Transform Mode to Snap and adjust Rotation Angle to snap rotation to fixed degree increments (for example, every 30 degrees).
- Set Scale → Transform Mode to Snap and adjust Snap Scale Value to snap the scale to fixed increments.
- Set either mode to Fixed to lock rotation or scale to a specific value regardless of drag.
What’s next
- Use Precise Place when you need one-by-one placement with a live preview and explicit transform controls.
- Use Edit to fine-tune a placed object’s transform after placement.
