3DS MAX – Micro Reference Manual – Animation – Constraints – LookAt
The LookAt constraint controls an object’s orientation so that it’s always looking at another object or objects. It locks an object’s rotation so that one of its axes points toward the target object, or the weighted average of target positions. The LookAt axis points toward the target, while the Upnode axis defines which axis points upward. If the two coincide, a flipping behavior can result. This is similar to pointing a target camera straight up.
It can drive:
– rotation
