For the Len Rig, we have a lot of exciting features:

Rig Mode (1-2)

Rig Mode Switch between 3-2 keys method to 2-2.

More about this you can find here in the Rig Mechanics.

Markers Mode

This option changes rig interpolation from keys to markers. So you could use additional in-between keys.

More about this you can find here.

Bezier Curve Movement (Non-linear Path points movement)

<aside> ⚠️ We continue to develop this feature, so it may not work as expected in some cases.

In the Len Rig , we implemented an experimental feature that allows moving points from position to position with a curved trajectory that looks more natural.

This option could be enabled from the Length Rig EffectAdvanced GroupBezier Curve Movement.

Curve Straight controls the radius of the curve.

Layer Scale / Rotation

The main goal of Len Rig is to work with paths. With them, we get all the advanced features of the rig. But unfortunately, it affects the performance of AE, as expressions are not fast enough with a large number of points on the path.

And sometimes, we need to attach additional Trim Path, Stroke, or other animations to the rig. By default, we've turned on rotation and scaling of the entire layer to ensure all the expressions can coexist on the same layer. By disabling them, only the paths will be rotated and scaled with the help of expressions. Also, it reveals the full capabilities of the path rig.

Without them, you get a constant stroke width and a working Range Stop function, which is described in more detail below.

If you need to rotate the whole rig but also to lock the beginning of the rig from the changes, here is:
