Click the orange button next to a CHOP to set its export flag.

Under the CHOP is a listing of all the channels. If the channel is overriding another parameter, the parameter appears in gray.

Beside the name of the channel is a text box where you can enter the path of a parameter to override. For example, /obj/model/tx will make the channel override the model object’s horizontal position. You can drag a parameter into this box to create a CHOP expression reference, or drag a channel into the right side to set up a channel mapping.
