Introduction

Prop models are geometry files created in a modeling program such as Softimage|XSI. You can place these prop models in Hammer, like adding props to a movie set.

Adding Prop Models

We're going to add some more entities, so pick the Entity Tool again.

Then pick prop_static from the entity list in the Objects Toolbar.

Select prop_static from the drop-down list.


Place the prop_static in the map by clicking on the floor brush in the 3D View.

Notice that the Object Properties dialog now shows the settings for the prop_static entity.

Place the prop_static entity on the floor by click in the 3D View.


Now we'll pick a model for the entity. If you closed the Object Properties dialog, you re-open it choosing Properties from the Edit Menu.

  1. Click the World Model field in the Object Properties dialog.
  2. Click the Browse button to open the model browser.

Switch to the World Model field.

Double-click the props_c17 folder in the model browser to open the sub-directory.

Double-click a folder to change to that sub-directory.

Double-click the model fence01a.jpg to select it, as shown here.

The model browser will close and the fence01a will be selected as the model for the prop_static entity.

Double-click the fence01a model to select it and close the browser.

Click the Apply button to confirm your changes.

Notice how the fence model now appears in the 3D View.

Click the Apply button to commit the changes and see the results in the 3D View.

Now we'll add a prop model with physics properties.

Switch to the Entity Tool.

Choose prop_physics_multiplayer from the entity list in the Object Toolbar.

Pick the prop_physics_multiplayer entity.

Place the prop_physics_multiplayer entity into the room by clicking on the floor in the 3D View.

Now open the Object Properties dialog by choosing Properties from the Edit Menu, if it's not already open.

The Object Properties dialog will now show the parameters of the prop_physics_multiplayer entity.

Place the prop_physics_multiplayer entity by clicking the floor in the 3D View.

Click the Browse button in the World Model field in the Object Properties dialog to bring up the model browser.

Scroll down in the browser and double-click the oildrum001.jpg in the props_c17 model directory, as shown here.

After clicking Browser, scroll down to the oildrum001 model, and double-click it.

Click the Apply button to confirm your changes.

Notice how the barrel model model now appears in the 3D View next to the fence.

Click the Apply button to make the change and update the 3D View.

Close the Object Properties dialog.

Close the Object Properties dialog.

Moving Objects with the Grid

You may have noticed that the fence model is stuck part-way into the floor. We need to move it up.

First, switch to the Selection Tool so we can move the object.

Switch to the Selection Tool.

Now select the fence model by clicking on it in the 3D View.

A yellow box will appear around the model in the 3D View, showing that you've selected it.

Select the fence model in the 3D View by clicking it.

Next, we'll move the fence model in the 2D Side View, since it's easy to see how it meets the floor.

To move the fence, click anywhere side the red bounding box in the 2D View, except in the very center of the box. Then drag the mouse cursor to the new location to move it.

When you drag it, make sure you don't accidentally grab one the 4 boxes in the center of the entity. These control the distance fading of the object, and we don't want to change that.

If you make accidentaly alter the fade distance controls, just choose Undo from the Edit menu to revert the change.

You may find that you can't quite line up the bottom of the model with the floor. The current size of the grid prevents it. Get it close as you can, and we'll fix that next.

Click and drag the fence in the Side View to move it.

For finer control, click the Smaller Grid button in the upper left corner of the Hammer window.

The size of the grid controls how objects are lined up to one another.

Decrease the size of the grid so the objects can be moved in finer steps.

With a smaller grid, now try moving the fence again. You can see that it's now possible to line it up with the bottom of the floor, as shown.

If you find that you still can't line up the fence with the floor, click the Smaller Grid button again.

Note: It's OK if the prop_static entity sticks into the floor a little bit.

With the grid size smaller, the fence can be lined up with the floor.
