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

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