Using fixed links

Introduction

If this processor is enabled, all parts will be separated in a link, associated with its parent using a fixed link.

Note

Doing this is likely to result in poor performance in physics engine, but can be useful for debugging.

config.json entries

{
    // ...
    // General import options (see config.json documentation)
    // ...

    // Adding fixed links, resulting in one link per part
    "use_fixed_links": true
}

use_fixed_links (default: false)

If set to true, a dummy base link will be added to the robot.

Alternatively, use_fixed_links can be a list of the links for which you want the fixed links to be added.
