Can I use Duik on After Effects XX? (replace XX by any version name)
Duik Bassel has been tested and works on all versions since CS6. That means CS6, CC, CC2014, CC2015, CC2017 and CC2018 support Duik.
We do not test Duik on versions older than CS6, so it may or may not work properly, we don’t know!) But you can test it yourself, it won’t break anything!
Duik Bassel does work on CS6, but the UI has a lot of issues we can not fix (they are issues in After Effects itself).
Although Duik works well on older versions of After effects, some features may be deactivated, like some tools working with Bézier paths only on CC2018 and newer.
Previous versions of Duik and After Effects
If you need older versions of Duik which work with earlier versions of After Effects, you can get them there: https://github.com/Rainbox-dev/DuAEF_Duik/tree/master/Release/Duik
Duik 15.52 works with CS4 and all more recent versions.
Duik 10 “oldafter” even works with After Effects 7.0!
Duik 15.52 can not be installed on the first After Effects v16.0 (CC2019) because of the missing
PresetEffects.xml file. This is fixed in After Effects 16.1 and more recent versions.
Can I keep (or safely remove) the older versions of Duik (15)?
Duik Bassel can be installed along with Duik 15 or any other older version, it will not replace them, and you can continue to use both without any issue.
However, if you don’t need Duik 15 anymore, you can safely remove it: just delete all files with “duik” in their names in the
ScriptUI Panels folder of After Effects, except
Duik Bassel.jsx which is the only one needed by Duik Bassel.
What is this ffmpeg file provided with Duik Bassel?
ffmpeg is another free software for decoding, encoding and transcoding media files. It is needed by Duik Bassel for some specific features, especially the Export to Audition function which is able to transcode audio files, thanks to ffmpeg.
After Effects shows an expression error saying
Unterminated string constant when renaming layers or puppet pins.
This is a known issue when using After Effects versions older than CC2017 on Mac OSX Sierra or more recent. If you rename elements using the Rename tool of Duik it should work correctly. This has been fixed in After Effects CC2017.
This is a bug in After Effects CC and CC2014 with windows and HiDPI screens (bigger than FullHD, 1920*1080), Duik can not do anything about it.
There are three workarounds:
- Set the scaling of the display to 100% in the Microsoft Windows settings.
- Run Duik from the menu “File/Scripts/Run script…” in After Effects, instead of the “Windows” menu. But in this case, Duik won’t be dockable.
- Update After Effects
Duik Bassel has three user interface modes, and the default one, the Rookie mode does not include the most advanced tools; it is designed to be easy-to-use but powerful enough to rig and animate any kind of characters. If you’re a beginner with Duik, you should not need the most advanced tools.
To change the mode of the user interface and switch to Normal or Expert mode, go to the settings panel.
When using some tools, this alert is shown:
Internal Verification Failure: Unexpected match name searched for in group" ( 29::0 ), what can I do?
This is a bug in After Effects CC2014 and CC2014.1, it is not an issue from Duik. Update After Effects to CC2014.2, or upgrade to a newer version.
Duik worked well, but it won’t start anymore. What can I do?
Sometimes, the files Duik needs to run smoothly get corrupted, especially (but not only) on Mac OS. If this is the case, Duik may not even be able to start anymore, or may be showing a script alert at start. In this case, follow the procedure described here to re-initialize it.
Changes between Duik Bassel, Duik 15 and older versions
Duik 15 came with an installer, Duik Bassel is just a zip, why?
Duik Bassel is so simple to install, it does not need an installer any more. Read the installation instructions.
The Duik 15 installer included Dugr too, where can I find it now?
Dugr is available on the Rainbox website.
Where is the Rotation Morph?
The Rotation Morph is replaced by the new Connector which is able to do exactly the same stuff, plus many more.
Where is the Orient to path tool?
This tool has been removed as you can achieve the same thing natively in After Effects, in the “Geometry/orientation” options of the layers.
Where is the IK Goal?
The IK Goal is replaced by the new Orientation Constraint which is able to do exactly the same stuff, plus many more.
To create what was the IK Goal, simply add an empty orientation constraint to the layer. To connect its rotation to a controller like what the IK Goal did when you had a controller selected, modify the constraint on the layer to constrain it to the controller you want.
Where is the hand goal checkbox?
This checkbox was removed, as the “Enable IK” option in the effect of the IK is already connected to the “goal” behaviour of the hand.
After a lot of tests, we came to the conclusion that the goal was needed only in IK and not needed in FK, so the easier way to (de)activate it was to link it to the IK button too.
Anyway, if you need to disable it but keep the IK active, you just have to add a Null object onto the end of the structure and link it to the forearm. Then, link the hand to this null object.
To control the rotation with the controller, you can also add an small expression in the null’s rotation:
value + pickWhipToTheControllerRotation
How can I scale a rigged character in Duik Bassel?
It is not possible to scale the rig itself yet without adjusting some expressions, but:
We’re still working on this, and still have hope that in a future version of Duik you’ll just have to scale the controllers.
With the new “Extract Controllers” feature, you can already scale a rigged character:
- Add the rigged comp into another comp.
- Select the precomposition layer and, in the controllers panel of Duik, click on “Extract controllers”
You can then animate from outside of the precomp, with the extracted controllers, AND you can scale the precomposition layer to scale the rig (the controllers will follow).
We think this is a good workaround, you just have to take care of the resolution as it’s a precomposition (and rasterization may not work properly with the rig), scaling up will damage it a bit, but scaling it down is ok.
How can I use the connector to connect a single slave property to multiple master properties?
As most of the tools in Duik, the connector uses expressions to connect the properties, and multiple expressions can not be easily combined into a single property. But there are work arounds! Read this section of the connector documentation to learn how to achieve this.
After Effects’ puppet tool (and Duik bones) is a pixel tool, but using continuous rasterization is using vector layers, so this raises some issues which are difficult to work around.
IK have to work with coordinates of the layers, and continuous rasterization may mess up those coordinates too…
However, the best you can do is converting those illustrator layers into shape layers (right click on the layer), which work better with the puppet tool and Duik. You can just precompose those layers too, while scaling them up in the precomposition to keep the quality of vectors.
How can I create a “Look At” effect?
What is called Look At in some 3D software and older versions of Duik is basically IK controlling an single element (Duik calls this a one-layer IK).
To add a Look At on a layer with Duik, first select the target, then the layer, and click on the Autorig & IK button in the Links & Constraints panel. This will create IK on the layer, and a controller to use as a target. You can then adjust the parenting if you wish, especially parenting the target layer to the controller.
When applying the walk cycle, the controllers of the hands seem to be deactivated, why’s that?
The procedural walk cycle animates the arms with Forward Kinematics (FK) and thus deactivates the Inverse Kinematics (IK). They do not need to translate anymore as the animation is on the angles of the individual FK controls.
If you want to animate/adjust the arms, you can either adjust the values in the Individual FK controls in the effects of the controllers, or you can re-enable the IK, but this will deactivate the procedural animation on the arms.
You can animate the switch between IK and FK, and Duik provides a tool to ease this IK/FK switch process.
