Instancing Shattered Geometry

Hi, having some problems with particle instancing.
Im trying to instance pieces of shattered geometry to particles randomly. The random part works fine however its the instancing that isn't. I've tried shattering a plane and cube, into individual pieces and instancing the pieces, but the geometry is being offset from the particles themselves and keeping the original transforms from wherever they were shattered, Iv'e tried deleting history which dosn't help. Ive tried with 3 shatter scripts 2 from creative crash - ctShatter and ktRockShatter, and the built in shatter effect, which all have the same problem - am i missing something simple?

Do you mean that the they're offset from the particle like they were offset from the center of the original object? When the object is shattered, do the shattered objects keep the same pivot as the had while they were still on the object? If so, maybe the pivot for each shattered piece needs to have its pivot centered? Maybe before instancing, try centering the pivot of each shattered object. I'd assume the instancer would look at the transforms of the object (which might mean the pivot's offset might cause issues).

Yeah thats what i thought, but centering the pivot dosn't have an effect:

The geometry is staying in the position that it was shattered - the one selected is the one instanced.

You have to manually center every shard at 0,0,0, then center pivot, freeze transforms, etc.

Do this by simply making a locator at 0,0,0, select every shard, hold down "v" and move toward the locator.

Instancing 101.
