Here’s a quick MEL wiggle expression for Maya’s transformation channels.
This is similar to After Effects’
Step 1. Go to Channelbox > Edit > Expressions…
Step 2. Paste the following
$wiggleF = 3; //Wiggle Frequency $wiggleA = 3; //Wiggle Amplitude $wiggleV = 1.1; //Wiggle Per Axis Frequency Variant translateX = noise(time*$wiggleF)*$wiggleA; translateY = noise(time*$wiggleF*$wiggleV)*$wiggleA; translateZ = noise(time*$wiggleF*(1/$wiggleV))*$wiggleA;
Step 3. Adjust Frequency, Amplitude and per axis frequency Variant to liking
Note: By default, the translate Y and Z frequency has a 1.1 (and ~0.9) multiplication to vary the animation on all 3 axes to avoid spatial linearisation.
