Graph Editor Fundamentals

Maya: Animation Basics

Overview

The Graph Editor in Maya is the animator’s tool of choice for animating big-budget movies and games. Its accuracy and broad range of features make it a vital resource for animators in the industry.

Despite its significance, some artists may find the editor daunting and, therefore, tend to overlook it.

This page will help you breakdown each of the various components of Maya’s graph editor illustrating how it functions using simple examples.

Jurassic Park: A Quick History Lesson

The film Jurassic Park was the pioneer in showcasing the potential of 3D animation in visual effect as compared to other techniques such as stop motion.

Steven Spielberg remarked that stop-motion animation appeared “jerky” during that era.

“The Making of Jurassic Park” documentary (below) recorded the moment the transition occurred from stop motion to CG animation, highlighting how the latter emerged victorious in the FX film battle, dominating movies and TV.

The Making of Jurassic Park

It was the ability of 3D animation to accurately track motion over time and smooth out the kinks that gave CG an edge over more traditional mediums.

 

About This Page

This page explains the fundamental aspects of Maya’s Graph Editor, using easy-to-understand cube examples.

But don’t be alarmed, as complexity emerges from these simple concepts. In the upcoming pages, we will illustrate how to utilize these concepts in more complicated situations.

Initially, the editor may appear perplexing or unimportant, but persist with it, and eventually, it will become a tool for liberation!


 

Hotkeys and C3dC Prefs

This page is taught from the Preferences/Tools/Hotkeys that are designed for animators to speed up workflow. All default hotkeys are the notes as well, along with menu items. The hotkeys can be downloaded with Site Subscription on this site.

Managing Animation Expectations

A lot of new animators are left feeling frustrated with their initial attempts at animation, particularly if they have already honed other skills.

It’s unreasonable to dismiss yourself as a terrible animator when you’ve barely started animating! Learning animation takes years of practice. Although it is a relatively simple skill to learn, achieving mastery requires significant effort and dedication.

We recommend taking these classes before reviewing this page:

2017/2018 Note

This page was recorded using Maya 2016. If you’re using newer versions of Maya you’ll notice changes to the Graph Editor icons and background. Thankfully, these are mostly superficial changes, and the core functionality remains the same.

1. Introduction (6:42 mins)

Here are the first videos to get you started in the Graph Editor.

To open the Graph Editor use the icons in the left toolbar (not in 2017/18). You can also use the spacebar hotbox by going to the top quadrant then left, or you can open a floating window under…

Graph Editor (7)
Windows > Animation Editors > Graph Editor

To navigate, use the same alt mouse combinations as you use in the regular viewport. Zooming on one axis is done with the following combination…

Zoom One Axis = Alt + Shift (hold) Right Click (directional drag)

More detail in the videos below…

Also not mentioned in this video is the floating window…

Graph Editor (7)
Windows > Animation Editors > Graph Editor

The hotbox also has a quick way of bringing up the perps/graph layout.

Many people have a preference to keep the Graph Editor floating on a second monitor. My preference is always to embed it below the main camera, usually the shot camera, that way the mouse tends to move less. I’ll usually pop out a floating persp window on the second monitor. But these are all up to the individual animator and also dependant on shot requirements.

4. Copying And Pasting Keyframes (2:51 mins)

To copy and paste keys use ctl c and ctl v.

Copy Key (ctl c)
Paste Key (ctl v)

If you’re on OSX, you can also use command c and command v.

Find these tools in the menu…

Graph Editor > Edit > Copy
Graph Editor > Edit > Paste (options)

In the paste options, you can change between “insert” and “merge” modes. You can paste in multiples, and there are other options too.

See the following video for more detailed information.

Highlight the number then type a simple equation… +=10

The frame time icons are all easy though it’s often easier to just use the hotkey Frame Selected (f).

6. Tangent Types (9:56 mins)

In this section, you can learn about Maya’s tangent types. These are all easy to learn, and they all have slightly different uses.

Tangents affect the behavior of curves between keys so change the motion over many keyframes.

The main tangent modes are…

– Auto
– Spline
– Linear
– Stepped

“Plateau” and “Clamped” are variations of “Auto” tangents. And then there are some hidden tangent types “Fixed” and “Stepped Next” under…

Graph Editor > Tangents

You can also set the default tangent types in the Preferences Window…

Preferences Window > Settings > Animation > Tangents

3. End Tangents (0:45)
Information
Spline tangents angle the tangent of a key as the direction from the previous key to the next key.

When a key is on the end or beginning of a curve the tangent will point directly to the next/previous key.

This tangent type is great when we don’t want objects to stop between keys, the motion will be smooth and floaty.

Information
Here we’ll discuss some more tangent types…

– Linear: Breaks the tangent and points each end to the next, straight lines/jerky
– Stepped: Removes any transitions, object will jump to the next position on the frame
– Stepped Next: Like stepped but in the reverse direction
– Flat: All tangent handles will be horizotal, no matter what the previous/next frames are doing

3. Splining End Keys (1:00)
Information
Auto tangents will automatically flatten tangents while previous/next keys are similar/same values.

When the keys on either side are different, the tangent will blend into spline mode.

End keys will always be flat.

Information
Plateau Tangents are virtually identical to Auto Tangents, only the Plateau Tangents have a little more range so the flat tangents will stay flat even if the next/previous keys aren’t exactly at the same value.

The transition from flat to smooth happens immediately, like a quick snap and not a blend (see video). This is similar to Auto Tangent.

Information
The Fixed Tangent Type locks the tangents so they don’t automatically change as we move keys.

A couple of tips here about selecting tangents and manually changing them too.

– It’s common to draw a box to select tangents
– Use middle click after selecting to alter the tangent manually

Default tangents can also be changed in Preferences Window (alt 6).

7. Break And Free Tangent Weights (3:32 mins)

You can obtain full control over your curves by breaking and freeing tangent weights.

To break a tangent, select a key and click the break tangents icon. Now you can tweak each side individually. To return to other tangent modes click on the regular tangent shelf icons.

Freeing tangent weights give you the ability to make your tangents longer or shorter.

You can only free tangents when you set the curve type to ‘Weighted’ mode. So switch to that curve type first…

Weighted Tangents : Graph Editor > Curves > Weighted Tangents

Then select the keys you want to free and click the “free tangent weight” icon.

The default ‘Non-Weighted’ curve type is best in most situations, but fussy animators can change Maya to default to the “Weighted” type with…

Preferences Window : Windows > Settings/Preferences > Preferences

12. Lock Reset (2:50)
13. Shift Tip (3:10)
Information
Maya offers total control over tweaking the angle and length of each side of the tangents. There’s a couple of important things to remember.

The main point is that there’s two different curve algorythms in Maya. The default tangent type “Non Weighted Tangents” doesn’t allow us to weight tangents (or lengthen/shorten).

This video explains all the details and a few tricks that will give you full control over the tangents in Maya’s Graph Editor.

9. Curve Management And Display Modes (3:59 mins)

Snapshot curves are useful for comparing animation. In this section, you’ll see how to use buffer curves to create these snapshots. They’re a little like a bookmark that we can return to at any time.

You can also display the curves in a variety of ways such as normalizing from -1 to 1 which allows you see all the curves at once in the same vertical scale.

No. Video Points
1. Buffer Curves (0:10)
2. Show Buffer Curves (0:15)
3. Swap Buffer Curve (0:25)
4. Rebuffer Curve (0:55)
Information
Buffer curves are a little like bookmarking but for animation curves. You can save the curves to a version and then compare at anytime without needing undo. This mode only gives two states so you can only have one backup curve at a time.
Command Menu/Description Hotkey

10. Cycling Animation In The Graph Editor (2:24 mins)

Cycling curves will help you to repeat animations such as run cycles.

Press the shelf icons to cycle your animation.

To disable the cycles and for other cycle types, use the menus…

Graph Editor Menu > Curves > Pre (and Post Infinity To) > Constant

Infinity curves will show you how the cycle is behaving. You can find the infinity curve display under

Graph Editor Menu > View > Infinity

For advanced cycling, there are a few cycle types to understand. Other cycle types include “Linear,” curves continue straight from their current path, and “Oscillate” where the animation will loop backwards and forwards. “Constant” is the default curve setting and keeps the object still after the last keyframe.

This video explores all the cycle modes.

To cycle the animation curves you can use the C3dC Hotkey Cycle Infinity Hotkey (alt o). Or we can use the Graph Editor’s toolbar icons.

Also remember that you can display infinity time (the dotted line) with Cycle Animation Curve : Graph Editor > View > Infinity.

And there’s more modes in the Menus like Linear Animation Curve : Graph Editor > Curves > Pre/Post Infinity > Linear and Cycle Animation Curve : Graph Editor > Curves > Pre/Post Infinity > Constant.

11. Snap In The Graph Editor (2:44 mins)

Learn to use snapping in the graph editor in this section.

Time-snap is usually “On” by default in the shelf. The value-snap value defaults to “Off”.

Keys usually should be on exact frame numbers, as you will only ever see the whole frames in your animation. Snapping to time will also allow you to update the keyframes easily.

Time snap can become more difficult while scaling as you’ll often want to keep animation with same relative spacing. But after scaling, you can snap to the closest frame with the global setting…

Graph Editor Menu > Edit > Snap

It’s rare to need to value snap for attributes (the up and down axis), but the option’s also there if you need it.

VIDEO 11.1 : SNAP SHELF ICONS (1:46 mins)

6. Snap Menu Item (1:14)
Information
Snap is handy in the Graph Editor for Time Snap. This should be on by default and it’s best to leave it at the default.

There are times when keys will go off whole numbers (integers) in such cases we can snap them back with Key Snap Whole Frames : Graph Editor > Edit > Snap

Command Menu/Description Hotkey
Key Snap Whole Frames Snaps all selected keys to closest whole numbers (integer) in time.

1. Unconstrained Drag (0:00)
2. Dope Sheet (0:18)
3. Animation Mixer (0:38)
Information
The last icons on the Graph Editor Toolbar here.

Unconstrained drag will limit the move tool to time only by default, not value. Hold shift for value drag, this is useful if you don’t like hold shift with the context sensitive style.

The last two icons are for opening the Dope-sheet and Animation Mixer.

12. Euler Filter And Baking (2:51 mins)

Learn about a couple of handy graph editor features in this section. You can find those in the menus…

1. Euler Filter
2. Baking (Plotting) Keys

The Euler Filter will help you get out of unwanted flipping issues regarding Euler and gimbal problems.

While the Euler filter isn’t a global gimbal fix, it can solve many flipping issues in regards to gimbal. The Euler filter will try to find the shortest path between keys and resolve some problems.

The Baking feature will bake keys to every frame which is great for exporting to other programs like a game engine. Or it can also be handy in many advanced animation workflows too.

VIDEO 12.1 : EULER FILTER (1:45 mins)

No. Video Points
1. Set Keys (0:00)
2. Rotation Issues(0:15)
3. Euler Filter Fix (0:53)
Information
The Euler Filter is an important menu item in the graph that will fix big rotation issues. These are usually related to curves rotating much more than we’d expect. 180 degrees on two axis or 360 on a single curve.

The filter will reset the curve values so that the object never rolls more than it should.

This will fail when objects are really supposed to rotate more than 360 degrees so be careful.

It also solves major Gimbal/Euler rotation errors, and not all gimbal issues are fixed with this tool. Gimbal is a large area that deserves it’s own page to explain all the issues and fixes but this one is a good one to try when your rotations are flipping more than you’d ordinarily expect.

Command Menu/Description Hotkey
Euler Filter Fixes extreme problems with Gimbal/Euler rotations by setting rotation between keys to the smallest values (less than 306) whilst maintaining key rotations in the viewport.

Information
Quick video covering some baking options which usually puts a key on every frame.

While baking keys it’s often easiest to use the shelf icon in the Animation Shelf (not graph editor). But in the graph editor we’ve the menu item Bake Channel Graph (shift alt b): Graph Editor > Curves > Bake Channel. Select the attributes in the channel box and run this menu item to bake keys.

We can also bake keys using the menu item Bake Keys (shift alt b). This is the window with most options. It can be found in two locations.

Animation Menu > Key > Bake Animation
or
Edit > Keys > Bake Simulation

Command Menu/Description Hotkey
Bake Channel Graph Bakes animation curves on every frame or as per the options, based on channel box selection.
Graph Editor > Curves > Bake Channel 		shift alt b (C3dC)

13. Extra Hotkeys: Make Hold, Move Snap and Zoo Tangent Works (3:22 mins)

In this section see three hotkeys that will help you to speed your workflow.

1. Make Hold
2. Move Snap
3. Zoo tangent Works

The make hold hotkey (alt a) (also covered in the ‘Selection Set and Pose Workflow Page’) allows you to change two keys instantly for pose-to-pose animation. These keys make the area between keys flat or static.

The move snap hotkey (ctl alt a) will move the selected keys so that the first frame of the selection moves to the current time. This hotkey is super handy and a little addictive once you get used to it.

Zoo Tangent Works has a lot of features regarding animation and function curves. It can change tangent types without being in the Graph Editor with extra functionality. It also has a lot of other features like tighten tangents and graph filters, setting default tangent types and more.

A couple of C3dC hotkeys explained in this video. Great to know.

Snap Key Retain (ctl alt a) will snap keys to current time whilst retaining the spacing between keyframes.

Make Animation Hold (alt a) is great for pose to pose blocking. See more on the Zoo Anim Workflow page.

VIDEO 13.2 : HOTKEY: ZOO TANGENT WORKS (1:37 mins)

No. Video Points
1. Zoo Tangent Works (0:00)
2. Set Tangents (0:05)
3. Tighten Tangents (0:47)
4. Graph Filters (1:10)
Information
Zoo Tangent Works (a (hold)) is a Zoo Tools hotkey with lots of tangent curve related functionality.

The most useful settings are quick access to all tangent types, and while this works based on selection in the Graph Editor you don’t need to be in the Graph Editor. This marking menu works in the timeline as well and if you’re not on a frame it will work backwards in the timeline to find the last.

The default tangent type is flat if you simply tap the hotkey without activating the marking menu.

Other functionality includes tools like Tighten Tangents and Graph Filters. A great hotkey to explore here for pro animators.
