Note: | |||
Instead of the low-poly model, you can use a '''NiTriShape''' or '''NiTriStrips''' block from any NIF (including the high-poly model!). | |||

*Right-click on the '''NiTriShape''' block again, and choose '''Mesh -> Strippify''' from the menu. This converts the the geometry from triangles to strips.

Choose '''Reorder Havok Blocks''' from the '''Spells''' -> '''Sanitize''' menu. To reorder the blocks manually, right-click on the '''1 NiTriStripsData''' block, and choose '''Block -> Move Down'''. Notice the reference number has changed to '''2'''. Repeat the '''Move Down''', so the number becomes '''3'''. | ||

===Fixing up=== | |||
NIFs created by this method appearanly always act like stone, no matter what their Material property is set to. | |||
You have to insert a bhkListShape to solve this problem. | |||
*Righ-click on the '''5 bhkRigidBodyT''' block. Choose '''Block''' -> '''Insert''' -> '''BHK''' -> '''bhkListShape'''. | |||
*Set the '''bhkRigidBodyT''' block's '''Shape''' property to the reference number of the new bhkLishShape ('''6''') in the '''Block Details''' window. BhkLinkShape is now linked to the bhkRigidBodyT block. | |||
*Set the '''bhkListShape''' block's '''Num Sub Shapes''' property to 1. Update the '''Sub Shapes''' array, just as you did when linked the high-poly model's NiTriShape to the NiNode. | |||
*Expand the '''Sub Shapes''' array, and enter the reference number of the bhkNiTriStripsShape ('''4'''). | |||
*Reorder the havok blocks. | |||
Example of the result NIF is [http://www4.rapidupload.com/d.php?file=dl&filepath=27622 here]. | |||

Select '''4 bhkNiTriStripsShape''' block. Double-click on the '''Value''' of the '''Material''' property (currently '''HAV_MAT_STONE'''). You get a drop-down list of available materials. This list with some explanation is available as tooltip (hold your mouse over the '''Type''' field of the Material property). Choose the material from the dropdown list, or enter the appropriate number which can be found [http://niftools.sourceforge.net/docsys/index.php?mode=list&table=attr&block_id=383&version=335544325 here] as well.

This setting controls the hit sound, step sound, arrow penetrability, and particle effect of the surface. | ||
*If you inserted a '''bhkListShape''' block, click on it, and notice that it also has a '''Material''' property. You can tweak the arrow penetration, particle effect, and sound by the material settings of the bhkListShape and the bhkNiTriStripsShape blocks. Arrows will only penetrate if both block's material is penetrable. | |||
