Use the Package Manager for quickly installing and updating tools, get it here:

Package Manager Getting Started

First you will need to Register your character under the "Setup Character" tab.
Select all your controls (don't forget hidden IK or FK controls, etc)

Click the "Register" button (check below if you run into any issues)

Select your controls and click "Mirror"

Your pose will be mirrored to the other side.
To "mirror swap" both sides, make sure to select both sides before clicking (check next tip).

Click "Select" to select the opposite side.

To add the opposite side to your selection, use SHIFT + Click on the button.

First select the object that you would like to use as a mirror plane and click "Set Mirror Plane Reference". (currently mirroring will be done over the X axis)

Next simply click "Mirror Via Reference Plane". (It's not reccomended to use this for ALL controls at once, its best used on as few controls as possible.)

• For the most part you can just make your selection and click "Register".
• If you do run into problems, you can go through the steps manually in the "Character Setup" tab. More details about this below.
• Of course if there are other issues not covered here, please fill out a ticket here https://github.com/eblabs/eblabs_community/issues/new/choose

The Package Manager makes installing a simple process, Package Manager Getting Started Although, if you still need to do this manually here's how.

Tools should be installed to a common eblabs_hub folder. The install path should be one folder up from the eblabs_hub folder. Make sure that there are blank __init__.py files within all folders.

.
├── eblabs_hub
└── __init__.py
    └── package_id
        ├── __init__.py
        └── unzip package contents here

install_path = 'E:/path/to/tools/folder/'
package_id = 'Reflektor'

import os
import sys
if not install_path in sys.path:
    sys.path.append(install_path)

import eblabs_hub.Reflektor.scripts.MainModule as tool
reload(tool)

tool.MainWindow.launch()
