This converts the the geometry from triangles to strips. Strippifying is needed becouse the collision geometry of ''arstatue01.nif'' was built from strips, and the low-poly model's geometry is going to replace it. | ||

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. | *Select '''4 bhkNiTriStripsShape''' block.

*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. | *If you inserted a '''bhkListShape''' block, click on it, and notice that it also has a '''Material''' property.

Note: The hit sound, and particle effect of melee weapon hit is controlled by the bhkListShape's material. Hit sound, and particle effect of arrow hit is controlled by the material of the bhkNiTriStripsShape. | |||
