|Anchor Transform by Robert Joosten stops feet sliding|
Rather than manually tweaking your animation to stop the feet sliding, rigger Robert Joosten has come up with a script that lets you anchor a transform for any given time range in your animation.
Anchor Transform was designed to be an easy to use tool that can be used to plant feet firmly on the ground when animating walks or runs. So, no more sliding feet.
Anchor Transform uses the Maya API to calculate new local space attributes. That means that it doesn’t have to loop over the frames, significantly improving the speed of the tool. The process will copy existing in and out tangents when Anchor Transform adds new keyframes.
Robert Joosten’s Anchor Transform script is free to download from his official site. You can visit the page for more information.
Kevin Richards, who is using the Anchor Transform Plugin at Cloth Cat Animation in Wales, had this to say:
"Cloth Cat have brought in a very useful plugin; it welds the foot to the spot while the character is walking so you don't have to go through the palaver of trying to match move the foot against the moving world control. It saves a massive amount of time and effort."
To install the Anchor Transform plugin, follow these steps
- First download the script from the official site. It is free, but you are given the option to pay for the service.
- Copy the rjAnchorTransform folder to your Maya scripts directory.
- Then, under the Python tab in the command line, type
import rjAnchorTransform.ui rjAnchorTransform.ui.show()
Middle mouse drag the Python script into your shelf and create a shelf; name it "slide", or "anchr".

Why won't it install?
As with many free plugins, Anchor Transform can be a bit fiddly to install successfully.
In theory, installation should pull up a user window that looks like this (see below).
Using the Anchor Transform Plugin
To use the Anchor Transform Plugin, select the foot control. Make sure that the box "From Time Control Selection" is unchecked. Now you can type in the "Start From" box the frame you want the anchor to start from, and type in the "End From" box the frame you want it to end at.
Other free Maya Plugins
Other free Maya plugins we recommend include the TweenMachine, Studio Library, the Parent Master, and also aTools. All are free to download and install, and super helpful ways to speed up your workflow.
