Understanding Key Driven Keys

Introduction

As 3D artists, we often rely on controllers to drive our animations and rigging. However, when working with set key driven keys, it can be frustrating when our controllers affect the keys we've already set up. In this article, we'll explore how to set up a Master Controller so that you can move it without affecting any driver/driven keys that have already been setup.

Understanding Key Driven Keys

Before we dive into the solution, let's quickly understand what key driven keys are. Key driven keys are a type of animation keyframe that is driven by a controller or a driver. When you set a key driven key, you're essentially telling the software to move a specific part of the animation based on the value of a controller or driver.

The Problem with Controllers Affecting Key Driven Keys

When you move a controller, it can affect the key driven keys that are connected to it. This can be problematic if you've already set up a complex animation with multiple key driven keys. If you move the controller, it can throw off the entire animation, requiring you to rework the entire setup.

Setting Up a Master Controller

So, how do you set up a Master Controller so that it doesn't affect any driver/driven keys that have already been setup? Here are the steps:

Step 1: Create a New Controller

First, create a new controller that will serve as the Master Controller. This controller will be used to drive the animation, but it won't affect any of the existing key driven keys.

Step 2: Set Up the Controller Hierarchy

Next, set up the controller hierarchy so that the Master Controller is at the top of the hierarchy. This will ensure that the Master Controller has no direct influence on the existing key driven keys.

Step 3: Create a Driver for the Master Controller

Create a driver for the Master Controller that will drive the animation. This driver will be used to move the Master Controller, but it won't affect any of the existing key driven keys.

Step 4: Set Up the Driver Hierarchy

Set up the driver hierarchy so that the driver for the Master Controller is at the top of the hierarchy. This will ensure that the driver for the Master Controller has no direct influence on the existing key driven keys.

Step 5: Connect the Driver to the Key Driven Keys

Connect the driver for the Master Controller to the key driven keys that you want to affect. This will allow you to move the Master Controller and affect the key driven keys, but only if you want to.

Step 6: Test the Setup

Finally, test the setup to ensure that the Master Controller is not affecting any of the existing key driven keys.

Tips and Tricks

Here are some tips and tricks to keep in mind when setting up a Master Controller:

Use a separate controller hierarchy: Keep the Master Controller and the existing key driven keys in separate controller hierarchies to prevent them from affecting each other.
Use a driver for the Master Controller: Create a driver for the Master Controller to drive the animation, but make sure it's not connected to any of the existing key driven keys.
Test the setup thoroughly: Test the setup to ensure that the Master Controller is not affecting any of the existing key driven keys.

Conclusion

In conclusion, setting up a Master Controller so that it doesn't affect any driver/driven keys that have already been setup requires some planning and setup. By following the steps outlined in this article, you can create a Master Controller that drives the animation without affecting any of the existing key driven keys.
