In this picture you can see that I've unselected the 'right collar' and the 'right shoulder'. Both of these body elements are totally hidden by the sweater's 'right collar' and 'right shoulder' elements and are not necessary in Bryce. Since some of the chest is visible around the neckline of the sweater, this will remain checked. If you are uncertain about a body element, leave that box checked - it can be deleted in Bryce later. As noted previously, the export Hierarchy List is not sizeable, making it difficult to deselect from the cascading list.
Care needs to be taken in deselecting.
With this figure, there are 3 hips objects - one for the figure, one for the sweater and one for the pants. This also shows the NECK of the sweater, which is not an actual object, even though it appears on the list. Make sure you deselect this item for any of the shirts. The export process is almost identical, but there are additional export options. After selecting the items in the Export Hierarchy box, you will then type in a file name.
