Manipulating props
It is very difficult to utilize props in an effective manner if you don't know how to manipulate them. In our project, you were asked earlier to move the house to better fit the terrain. You have been briefly introduced to the gizmos and direct manipulation, but now that you have an idea of prop placement, we need to go into a little more detail about gizmo versus direct manipulation of a prop.
Selecting the tools
Select, Move, Rotate, and Scale are the main tools for manipulation props in the workspace and are shown in the following image:
Select tool: You can directly click on the prop with the Select tool by double-clicking on the prop in the workspace. This also applies to actors and accessories. You can also select the prop by double-clicking on the props name in the Scene Manager (shown in the next image) on the lower part of the left menu:
Note
The Scene Manager is a very versatile part of the iClone user interface. To ensure that you don't accidently move a prop or other item in the workspace, you can lock that item in place by checking the Freeze box. Visibility is also toggled on and off via the Show checkbox so you can work on an object behind or otherwise blocked by a prop. Render State will allow you to set the real-time preview render of each prop to wireframe, smooth, or normal if you need to reduce the load on the real-time engine while you work. This affects individual props instead of the entire scene. It also displays the all-important face count of the prop under the Info column.
When a prop is selected, the body of the prop is surrounded by a bounding box with yellow corners. This makes for easy identification of the selected prop or other content.
For direct manipulation, left-click and move your mouse and selected props will move or rotate with the mouse. To increase the speed and distance, hold down the Shift key while moving the prop with the mouse. This is great for working in a large scene or when you first bring a prop into the scene. However, there will be a time when you will need more precise control.
As you may have already guessed, precise manipulation is done with the Gizmo tool. The following image shows different props with different gizmos—Rotation, Move, and Scale:
The Gizmo tool is color coded for each axis. If the gizmos are not visible, use Ctrl - Q to turn them on and place your cursor over the color section of the gizmo that matches the axis you wish to manipulate. To Move or Scale all of the axis at once, use the yellow center area of the gizmo. Any manipulation in the center of the gizmo will affect the entire prop.
Experimentation with the gizmos will quickly teach you how they work as they are very simple methods of precise manipulation.
We can enter numbers directly into the prop's X,Y, and Z input boxes. We can use the up and down arrows for fine tuning. The following image shows the inputs used in this example:
Tip
Manipulating props
A combination of the manipulation methods can give you a lot of control and very quick placement of props and other content. Use drag-and-drop to place a prop into a scene. Use the object Gizmos (Ctrl + Q) to place the props more accurately based on rotation and movement along the axes. We can also use direct input into the X,Y, and Z Input Boxes for final tweaks to placement. This yields a very strong measure of control over speed and precision of prop manipulation.
