Then in the details window for the bhklistshape set the number of subshapes to the number of shapes you intend to use. Then right click the Subshapes array and update it so that you have open slots. Double click those and input the block numbers of your subshapes (for boxes using a convex transform shape to control it, it's the number of the convex transform shape which you should use). | Then in the details window for the bhklistshape set the number of subshapes to the number of shapes you intend to use.

The sequence of the block numbers has to be very specific for Havok in a way that is not true for trishapes.

But what about those of us not fortunate enough to have the latest version of 3DS? Well, do not despair.

Well, do not despair. Because although the route is a little more arduous the creation of collision meshes directly matching your mesh is still a possibility. The following step by step will show how to produce the same end result as the plugin afore-mentioned via a few simple NifSkope hacks. But first a warning: | ||

The additional element in doing this though is to also create and export a less detailed version of your mesh which will be used as the collision model. In fact you may need to export more than one additional mesh if you're new model is going to be built from different materials. For instance the stone sections will need to be exported as one part, the wood sections as another and so forth. | The additional element in doing this though is to also create and export a less detailed version of your mesh which will be used as the collision model.
