Filters in general

Filters are an experimental feature that make it possible to modify data from the Smartsuit so that it is better suited for specific use cases. Some filters can be used live, others are only for editing takes. To begin working with filters, please download the latest firmware, you can follow this link to see how this is done.

One example of a filter is the Locomotion filter. It allows your feet to unlock from the floor at certain times, which, for instance, makes jumping possible. Keep in mind that these filters are in an experimental stage and will consistently be improved. How significantly these filters affect your own Smartsuit capture data will depend a lot on your individual project.

When you open Smartsuit Studio the Locomotion and Toe Bend filters are turned on by default. Enabling and disabling live filters is done by clicking the filter menu button on the right side of the header next to the info button.


Locomotion

What does it do?
Locomotion simulates the position of the character by estimating when contact with the ground occurs. This can be edited in the playback for higher precision.

When would you use it?
Locomotion allows for jumping and / or running and might be preferable in use cases where both feet are allowed to be off the ground at the same time. Locomotion might also be preferable when performing movements such as hand stands, somersaults, backflips, and miscellaneous acrobatics.

Live / Playback: Yes / Yes


Foot IK

What does it do?

Foot IK improves the contact of the feet with the floor by applying extra "pull" on the feet when nearing the ground

When would you use it?

The Foot IK filter can be useful when making a recording that requires feet contact to be spot on. You can define a "pull down" value to increase or decrease the pull of the body - and thus the feet - to the ground, as standard it is set to 0.2, should you not want too much knee flex you can set the value to 0.

Live / Playback: Yes / Yes


Treadmill

What does it do?
Treadmill keeps the character fixed in a position in space.

When would you use it?
Imagine you are doing a skiing animation in which you'd like a camera with a fixed distance to the character following it at all times. By enabling the Treadmill you force the character to stay in the same position. This will create a neutral position that you can then keyframe and have complete control over later in the pipeline. Another example is if you have a cyclist on a racing bike or BMX. In both cases your body movement is confined to a prop, or a vehicle, which you want to able to move around independently in a terrain afterwards.

Live / Playback: Yes / Yes


Toe bend

What does it do?
The Smartsuit Pro doesn’t have a separate instep and toe sensor; it has just one on each foot to cover the whole area. The toe bend filter imitates how the foot would normally bend when touching the floor.

When would you use it?
When you are standing on your toes or performing movements where a curvy transition between the instep and toes would be preferred. A specific use case where you would not have Toe Bend enabled is if you were performing a pirouette, or most any movement associated with ballet.

Live / Playback: Yes / Yes


Drift fix

What does it do?
It allows you to change the starting point and end point of a take. By turning on this filter you see a start and an end handle in the scene: these can be moved around on the floor plane (XZ).

When would you use it?
When the character does not end up in the desired position you can use the start and end markers to correct the position in playback. Let's say that you are recording and run quite far in one direction. You run back to where you started and stop the take, but see that you drifted a little. In this case, you are able to change the point in space that your character ends up at.

Live / Playback: No / Yes
