RED Functionality Overview

While some is universal, much of RED's functionality is broken up into 6 modes - Brush Mode, Face Mode, Vertex Mode, Texture Mode, Object Mode, and Group Mode.

Camera Control

 * See Camera Movement Hotkeys

View Ports
The main portion of Red's interface is divided into four view ports. The view ports are how you see and interact with the world in Red. Each of the view ports is identical and can have any view assigned to it but at least one view port must be assigned to Free Look. You could, for example, have 4 Free Look view ports if you wished. This would, however, take a bit if CPU power to render. You can select a view port to be active by simply moving your mouse over it. There will be a red line on the outer edges of the view port to show it is active. You can "solo" any view port by moving your mouse over it and press "F4". This will stop rendering all the other view ports. You can "un-solo" and set all view ports to their default size by press "F5". The view ports can be arbitrarily resized by moving the center of the view port frame.

There are 2 types of views - Free Look and Orthographic. Free Look is the 3D view of the world and you can move in any direction. in this view. An Orthographic view is a wire frame view of the world and you can only move in 2 axes. The default are (clockwise from upper left) Top, Left, Front and Free Look. Right clicking over the view port's name (in the upper left corner) will bring up view port pop-up menu with the following options:
 * View Select: This allows you to assign a view to the view port you are currently in.
 * Show Grid: This toggles the grid on or off in that view port. The grid settings under General Preferences overrides this setting.
 * Show Links: This toggles object links on or off in that view port. This will show all links between all objects whether they are selected or not.

Status Window/Console
In Red, the status window displays information output by the editor. Whenever you rebuild your level, the build information is displayed in this window. When you select a brush in brush mode, it's dimensions, UID and time index are displayed here and when you select and object, it's UID and script name are displayed in this window. Also, if you have Holes in your level, the status window will turn red to indicate this.

Texture Mode
Textures are what you see on the polygons (faces) in a level. Textures are applied to all surfaces of a polygon in RED editor. When calculating/adding lightmaps, another texture map (called a lightmap) is added to each surface of your level (except for "Full Bright" faces). This is done by baked grayscale images which tells the surfaces how illuminated they should be. RED supports Smoothing Groups for the lightmaps to make lighting appear seamless on rounded surfaces.

Hotkeys

When in Object Mode you can create, place, and perform operators on objects in your level.

What is an object?

 * See RED Objects for detailed information on objects, including a list of available object types.

Hotkeys

 * See Object Mode Hotkeys

Operators

 * Object List: This lists all objects and events you can place in a level. Clicking the "+" sign will expand that part of the Object List. The currently selected object is always highlighted and double-clicking on an object in the list will create an object at the current location of your camera with your camera's current orientation.

What is a group?

 * See RED Groups for detailed information on groups.

Hotkeys

 * See Group Mode Hotkeys

Operators

 * Groups: This is the group tree. Groups are broken down into three categories. The first is Master Groups which are created by the editor and cannot be modified. Whenever you create anything in the editor, it will be added to a Master Group. The second category, User-Defined Groups, are groups that you create. Using User Defined Groups will make the level design process much easier for you. The last category is reserved for Moving Groups. The currently selected groups will be highlighted in blue.
 * Create: Creates a User Defined Group from the currently selected brush(es) and/or object(s). Clicking this button will bring up a dialog box so you can name your new group. If you choose not to name a group, it will be automatically be named "temp###". "Temp" group names are automatically and incrementally named.

Brush Clipping
Accessible via Brush Mode

The brush clipping tool allows you to cut or split a brush or brushes along a plane defined by two control points. The plane is indicated in the editor by a blue line. At the line’s center is a small line segment called a normal, which is used to indicate which portion of the brush will be discarded when the brush is cut You must select at least one brush before starting the brush clipping tool. Then place two control points in any of the views (except for the free-look view). To place a control point, simply click where you want the link to be created. The editor will take the control points, align them with the grid, and draw the line between them indicating the clipping plane. Now click on the Split Brush or Cut Brush button to perform the clipping operation.


 * Reverse Normal: Click this to change the direction of the clipping plane’s normal. This allows you to cut the opposite portion of the brush(es).
 * Split Brush: Click this to split the brush(es) along the clipping plane. This adds faces to the brush in question, which can be very useful in texturing larger brushes.
 * Cut Brush: Click this to cut the brush(es) along the clipping plane. The direction of the normal will determine which side of the brush(es) is cut.
 * OK: Click this if you want to accept the clipping operation and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes made by clipping operation..

Fuse
Accessible via Brush Mode

Fusing is used to make 2 or more brushes into 1 brush. While this function is not used that often, it comes in handy in certain situations. Once you fuse brushes together, you cannot "un-fuse" them. You can undo the operation but if the undo buffer gets refreshed and the fuse operation you just performed is gone, you are out of luck. It's a good idea to make a habit of backing up brushes before you fuse them together. The easiest way to make a backup of the brushes is to create a User Defined Group and save the group out. This way, if you need the original separate brushes back, you can just load the group. You can only fuse 2 brushes at a time. If you try to fuse more than 2 brushes at once, faces will disappear. When you fuse brushes together, common vertices are welded together.

To use the Fuse function, simply click on a brush to select it then CTRL + click on the other brush you want to fuse to the first brush. Now click on Fuse, rebuild the level and you're done.

Carve
Accessible via Brush Mode

Carving is used to "permanently" cut one brush with another brush. This is basically how the engine works any way but carving allows you to create a single complex brush that would normally take many brushes to create. Sometimes, this makes managing brushes easier. You can only carve with 2 brushes at a time. If you try to carve with move than 2 brushes at once, faces will disappear. You can only carve a solid brush but it can be carved with either an air or solid brush. The brush that is earliest in time (out of the two) will be the bit that carves out of the second brush, which must be the later in time of the two. The time index of brushes is displayed in the Status Window. Once you carve a brush, you cannot "un-carve" it so it's a good idea to make a backup of the brushes before you carve them. Brushes can only be "uncarved" with Undo but if the undo buffer gets refreshed and the carve operation you just performed is gone, you are out of luck. The easiest way to make a backup of the brushes is to create a group and save the group out.

To use the Carve function, check the time indexes of the two brushes you want to use for carving. If you need to change their times, use the Start of Time and End of Time buttons to move them in time.

If the time indexes of the brushes is all set, then just select both brushes and click carve. Then move or delete the brush you carved with and you will see how the new carved brush looks.

Mesh Smooth
Accessible via Brush Mode or Face Mode

Mesh smoothing is an operation that can be applied to a whole brush mode or select faces Basically it does what it says. It smoothes out a brush or group of faces by adding more faces. Technically, mesh smoothing creates a new face for every the edge and vertex of the selected faces. Mesh smoothing does add more faces so be careful when you use it.


 * Strength: This controls the size of the original faces of the brush. Lower values will make the original faces smaller. The default is 0.50.
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.

Bend
Accessible via Brush Mode, Face Mode, or Vertex Mode

Bend is a very powerful tool that allows you to create curved brushes quickly and easily. To create a curved brush, you have to create a brush that is segmented. You can do this by either splitting the brush when you create it or by extruding faces after you create it.


 * Angle: The amount the brush is bent.
 * Bend Point: Changes whether the bend occurs around at the beginning, center or end of the brush.
 * Offset: This offsets the the bend point by X meters.
 * Around Axis: This sets the axis that the brush will bend around.
 * Along Axis: This sets the axis that brush will bend along. The will typically be the axis that is the longest dimension of the brush.
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.

Twist
Accessible via Brush Mode, Face Mode, or Vertex Mode

Twist allows you to create very complex curved brushes quickly and easily. Think of Twist as doing multiple bends at once. As with Bend, you have to create a brush that's segmented. You can do this by either splitting the brush when you create it or by extruding faces after you create it.


 * Angle: This sets the amount of the twist.
 * Around Axis: This sets the axis around which the brush will twist. For best results, always twist around the axis of the longest dimension of the brush
 * X/Y/Z Offset: These values will move the center point around which the brush is twisting. By selecting minimum, center or maximum you can easily move the point around which the brush twists without having to adjust the X/Y/Z offset values
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.

Stretch
Accessible via Brush Mode, Face Mode, or Vertex Mode

Stretching allows you to change the size of brush, a face or a group of vertices. The stretch dialog is available in brush, face, and vertex. While you can manually move a face or group of vertices to resize a brush, stretching lets you quickly enter precise dimensions.


 * Height: You can type the height in or use the up/down buttons to change the current value.
 * Width: You can type the width in here or use the up/down buttons to change the current value.
 * Depth: You can type the depth in or use the up/down buttons to change the current value.
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.
 * Copy: This is very handy feature. If you want 2 or more brushes to be the same size, you can use copy and paste to copy one brush's dimensions to another. Simply select the brush you want dimensions from, open the Stretch dialog box, then click Copy. Now select the brush you want to copy the new dimensions to, open the Stretch dialog box for that brush, click on Paste and you're done.
 * Paste: See above.

Jitter
Accessible via Vertex Mode

Jitter allows you to randomly move vertices (within an amount that you define) to create more natural shapes with your brushes.


 * Distance: This sets the maximum distance a vertex will randomly move from it's original position.
 * Jitter Again: This will move the selected vertices again.
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.

Bevel
Accessible via Face Mode


 * Height: This sets the distance of the beveled face from the original face.
 * Inset: This sets the distance that the vertices of the beveled face are moved to (positive values) or from (negative values) the original face.
 * OK: Click this to confirm any changes you have made and close the dialog box.
 * Cancel: Click this to close the dialog box and lose any changes you have made.

Texture Browser
Accessible via Texture Mode

You can use the texture browser to view and select textures to apply to faces in texture mode. The texture browser is also used when selecting a bitmap for a Liquid Room or Decal.


 * Current Texture: This displays the texture you currently have selected to apply. The name, size and format are displayed below.
 * Show Only Used: This flag will only display textures in the browser that you have used in your level. This really speeds up the time it take to load large directories and helps you find textures you have used much faster.
 * Folder: This displays the current texture folder you are browsing. Selecting "All" will display every single texture in the game in the browser window. Please note that, depending on the speed of your computer, this can take quite a while.
 * Sort By: You can either sort the textures you are browsing by name or date. Sorting by date makes finding textures you just created or added to Red much faster.
 * Name: This allows you search for textures in the current directory by using part of a texture's file name (i.e. mtl_bla). You cannot use wildcards like "*" in your search.
 * Material: This allows you to sort the current texture directory by material type. Most directories are only one material type but some like Trim are more than one material type. See RF1 Materials for a list of available materials and their properties.
 * Display Size: This changes the sizes of the thumbnails displayed in the browser window.
 * Show Tiled: This flag will show the currently selected texture tiled in the main texture browser window. You can also show the currently selected texture tiled by right clicking over the main texture browser window.
 * Favorite Textures: This allows you to select up to 8 different textures for quick and easy access. To change a favorite texture, simply double click on it in the main texture browser window then click on the Change button beneath the spot where you want the new favorite texture to be.
 * OK: Click this once you have selected the texture you wish to use.
 * Cancel: Click this if you wish to exit the texture browser.

UV Unwrapper
Accessible via Texture Mode

You can use the UV Unwrapper to manually edit UV coordinates of faces for texture projection.


 * Movement Increment: Set movement distance with keyboard.
 * Rotation Increment: Set rotation amount with keyboard.
