Prepare your character for full body IK

Before you can create the FBIK effectors for your biped character, you first need to make sure that your character is in a pose that will produce the best FBIK results.

For a biped, your character should be in a “T” pose known as the T-stance and should be facing down the +Z-axis. Also, your character’s feet should be straight, its hands should be flat with palms facing downward, and its thumbs should be pointing down the +X-axis. You character’s pose does not need to be an exact T-stance, but it should be a close approximation.
For a quadruped, your character should be facing down the +Z-axis and its paws/hooves should not be flat on the ground but should be pointing downwards with all their toes fully-extended towards the floor. Also, if your character has a longer neck (like that of a camel or giraffe), its neck needs to be extended (for example, like it is reaching for a leaf) and pointing down the +Z-axis.
