标准追踪约束

The Track To constraint makes an object or bone point towards a certain target, then roll to make a certain local axis point upwards. It's typically called "Look At" or "Aim" in other 3D software.

If the constraint owner is almost directly above the target, the roll around the tracking axis will become unstable. For this scenario, it's recommended to use the 阻尼追踪约束 instead.

选项

标准追踪约束。

目标

要指向的物体或骨骼。

追踪轴

The local axis of the owner that should point at the target. For bones, this should typically be Y.

A negative axis will make the owner point away from the target instead.

向上

The local axis of the owner that should point upwards in the world.

Important

The Track Axis and the Up axis must be different. If they are the same, the constraint will stop working and its icon will turn red.

目标 Z

Align the owner's Up axis as closely as possible to the target's Z axis instead of the global one.

目标/主体

The spaces for evaluating the target and owner transforms.

影响

How strongly the constraint affects the owner.
