Link

Link is a very convenient function for you to simultaneously move, rotate or scale one or more objects, such as an actor, accessories or props, without adjusting them one by one. You do this by linking them to a specific parent object.

The linking relationship can be set as a key, therefore, you may set a link key at one time and set an unlink key at another. By means of this concept, you may have the object specified to be transformed during different time frames.

We will use props to describe the linking process.

Link

  1. Drag and drop the desired prop(s) into current project.

  2. Double click on the prop to pick it.

Drag and drop the crate

  1. Scroll to the Linkage section and click Pick Parent button.

  2. Navigate on the 3D viewer and click on the target object. The prop may be still at the wrong position.

Pick the lifter of the forklift as the parent of the crate

  1. Adjust the position of the prop for better placement if necessary then click the button and check the correct sub-node is selected in the Link to Sub-Node panel, check the Align Position to Parent box and click OK. The prop then will be forced to align to its parent.

The crater is aligned to the lifter

  1. Move the parent object to test the result.

Note:

  • The Link relationship can not be stored along with the parent if you add the parent into the Content Manager/Custom library. It can only be saved in the project.

  • If you wish to keep the relationships between the parent and the child, Attach method is highly recommended.

Change Link Parent

You may link your object in one frame to a target and then link to another target at another frame. The transform data of the object then will be driven by different parents in different frames. Following the example above, we will now go on more to describe this feature.

  1. Go to the desired frame when the prop will be linked to another parent.

Go to the frame for changing the linking parent

  1. Click the Pick Parent button again.

  2. Click on the desired parent on the 3D viewer. Now the parent is changed.

The crate is now linked to the train.

  1. Move the new parent object. The transform data of the prop will now be controlled by the new parent.

The train moves away with the crate
