Hammer Map Tools Toolbar
The Selection Tool allows you to accomplish a number of things. It is used to select, resize, rotate, shear, and move objects.
The Magnify Tool allows you to increase the magnification factor of the 2D views. Click once in a 2D view to increase the magnification level. Zoom back out again by clicking the right mouse button. Zoom in and out can also be accomplished by pressing the "+" and "-" keys on the numeric keypad while the mouse cursor is in a 2D view. The mouse wheel can also be used to zoom in and out.
The Camera Tool allows you to place and modify cameras within your level. More information can also be found in the article about viewports.
The Entity Tool allows you to place point-based entities in a map. Point-based entities are those entities which exist only at a point, and do not rely on a brush for their effect. Also see Applying Materials.
This is the basic creation tool in Hammer. The Block Tool allows you to create any of the different types of primitive shapes and prefab objects in the New Objects Bar. Also see Creating Brushes for additional information.
This button toggles the Texture Application mode on and off. Texture Application mode allows you to edit the properties of individual brush faces and create displacement surfaces. For more information, see Face Edit mode.
When Apply Current Texture is pressed, the current texture selected in the Textures Toolbar is applied to all faces of the selected brushes, replacing all textures existing on the objects. Texture scale and shift parameters are unchanged – the new textures will use the existing parameters on the objects.
The Apply Decals tool is used to place decals upon objects. A decal is a texture that can be placed on top of another texture, combining the two.
The Overlay Tool is used to place overlays upon brush and displacement surfaces. An overlay is similar to a decal, but has some additional properties to control how the overlay is applied to the underlying surface.
The Clipping Tool allows you to slice the currently selected brush using clip planes. Clip planes enable you to precisely make a cut in a solid, leaving you the option to keep either or both parts of the resulting two solids. Also see Reshaping Solids.
Vertex manipulation gives you complete control over the shape of a solid object. Using the Vertex Tool, you can reshape the object by manipulating individual vertices and brush edges, easily creating odd (and sometimes invalid) shapes. Also see Reshaping Solids.
(Only aviable in the Portal 2 & Alien Swarm SDK.) Export the selected brushes to Maya.
