SPACE + Z same, but this time the Z axis will be aligned with the surface normal. SPACE + X same, but this time the X axis will be aligned with the surface normal. Here are the shortcut keys that allow you to do this: SPACE the special op square will appear and if you click the left mouse button inside the square and then drag while hovering a terrain/mesh, the object(s) and the gizmo will move along the terrain/mesh surface and the object's Y axis will be aligned with the surface normal. With it you can place an object (or collection of objects) on the surface of a mesh and also align the object's axes to the surface normal. 2ģ Mesh Surface Placement The translation gizmo can be used to greatly speed up mesh surface placement. I will be referring to this as the 'special operation square' or 'special op square' for short. When a special operation is being performed, a square will appear in the center of the gizmo. Note: The translation gizmo can be used to perform certain special operations, like the camera axes translation discussed above or vertex snapping etc. This is a little bit like performing a translation in screen plane. Clicking and dragging the mouse while the square is selected will perform a translation along the camera right and up axes.

If you hold down the SHIFT key, a square will be shown centered around the gizmo position.

Clicking and dragging one of the squares will allow you to perform a translation along 2 axes at once. The gizmo also has a set of squares at the intersection of the axes.

The following image shows a screen-shot of the translation gizmo: Using The Translation Gizmo If you click and drag one of the gizmo axis (the selected arrow changes the color) you will perform a translation along the corresponding gizmo axis. 2.1 The Translation Gizmo The translation gizmo allows you to move objects around in the scene. We will also talk about transform spaces and transform pivot points. In this chapter we will take a look at how the gizmos work and all the properties which can be modified for each gizmo. 2 The Gizmos The term 'gizmo' refers to the manipulators used to manipulate the objects in order to move, rotate and scale them in space they are the 'tools' of the World Editor. It provides information about all the gizmo properties and system settings. 2 Table of Contents 1 Introduction 2 2 The Gizmos 2 3 Camera control 5 4 Hotkeys 6 5 File menu 7 6 Tools 8 7 Objects 9 8 Materials 17 9 Settings 21 1 Introduction This document explains how you can use the World Editor.
