To add Auto Bank, right-click an object and select:
Add Automation > Auto Bank
Auto Bank is most commonly used to add extra roll or pitch to an object based on its movement. This is determine by the object's velocity, calculated as the difference in position each frame.
Play Timeflow to preview Auto Bank accurately. Auto Bank relies on relative change in movement as it occurs and cannot calculate banking at arbitrary times. Therefore, whenever there are abrupt changes to the current time (such as when dragging the playhead), auto bank calculation may be incorrect.
To see Auto Bank perform properly, allow Timeflow to play uninterrupted. It may also be necessary to rewind sufficiently so there is enough lead time to fully apply smoothing.
Select the game object and view it in the Inspector view to configure settings.
Determine the input source of movement from which auto bank is calculated.
Enable this to force calculation in world space, otherwise positions are treated as local coordinates.
Uses the object's transform position to generate banking. Select the axis of movement (position) to generate banking from.
Time Offset may be adjusted to either look ahead at upcoming turns and lean into the curve (like a pilot or driver would do), or time offset can be negative to delay banking (reacting to rather than anticipating each turn).
This mode uses another channel (on the same object) as an input value to calculate Auto Bank. This can be a position channel, or any numeric data type, though just 1 axis or float value is used as input.
Use this mode if the object position is animated on other channels, whether separately or combined.
This multiplies the movement input value, controlling the overall intensity of banking.
A lower scale value results in more subtle banking overall, while increasing the value amplifies it. This can vary quite a bit depending on each situation where Auto Bank is used, so may take some experimentation to find the right settings for the effect you wish to achieve.
This controls the amount and degree of rotation, applied to the Axis selected. The Banking value affects how much banking is applied over the change in movement. A lower value reduces the effect, and a higher value increases it.
This sets the maximum rotation value allowed for this axis. The value is enforced as both a negative and positive rotation.
Use this mode if you wish to set explicit minimum and maximum values. This will keep the banking rotation within the rotation range specified.
Use this mode to allow banking to rotate endlessly.
If no rotation limit is enforced, it is possible for rotations to go to infinity. Since infinity is not a real number, this condition will result in the object rotation being reset to 0. This ca be avoided by using a very high limit, or adjusting the movement scale and banking values to keep the rotations within a reasonable range.
If enabled, the banking rotation is reset to 0 whenever Timeflow rewinds or loops. However, for looping paths you may wish to disable this for seamless banking when looping.
This sets the rotation axis to apply banking too.
If Invert is enabled, the value range is swapped.
Enable Invert to make the object bank in the opposite direction. This determines whether the object is leaning into or away from turns.
Optionally sets the base rotation of the object.
Use this to adjust the heading so the object is facing the direction desired.
Auto Bank vs Rotation Conflict If Auto Bank is conflicting with other object rotations, you might consider applying Auto Bank on a parent or inserting a new transform to isolate the banking movement from other rotations.
Applies temporal blending to create smoother more graceful banking.
Be aware that setting Smooth Time to zero or a very low value is likely to result in abrupt and sometimes unpredictable changes in banking rotation. If even a small amount, smoothing is recommended for best results.
If enabled, the banking rotation accumulates over the distance travelled (or based on the change of the input value). Use this option for objects that spin or corkscrew.
This multiplies the banking amount when cumulative is enabled to reduce the banking so that it is easier to control. Since cumulative mode amplifies banking, the dampen amount is used to counteract that. This value may be adjusted to increase or decrease the rate.
For common features please refer to and .
Use a from the same or different object with optional Time Offset. The default offset is 0.25 seconds to allow a bit of lead time to anticipate banking.
This mode can also be used for more creative effects by adding a channel as the input, and then using to direct channels from other objects or calculate input data.
Channel Value mode also supports Time Offset, which works similarly as described above for the mode.
Determines the minimum change of input (i.e. movement) required to register a change. If the relative change in input value (from any ) is below the Threshold, it is ignored.
If Auto Bank is applied to the same object it bases movement from, it may be helpful to use , set in the Update Settings. This will result in Auto Bank updating after all other behaviors have been updated. This can fix jitter or shaking behavior that may occur otherwise.
