[ChunkMerge] bhkCollisionObject in sub-nodes not recognized in Templates

[hexabits]

Example: meshes\architecture\solitude\scastlewall04.nif

0 BSFadeNode
    ...
    7 NiNode
        12 bhkCollisionObject

When using this mesh as a Template to reinsert fixed collision back into itself, ChunkMerge reports that the NIF has no collision.

The compounding issue here is that the ChunkExtract issue means that to modify collision around the visible part of the mesh, you have to move the collision into place in 3ds Max, but when you do this, you are changing the XYZ values of the vertices, e.g. X +100, Y +100, Z +100. Then, if you would ChunkMerge the collision back into the NIF at the existing depth and transform you would be doubling up the transform e.g. X +100+100, Y +100+100, Z +100+100.

So both ChunkExtract and ChunkTransform should be compensating for all parent transforms for the bhkCollisionObject. When Extracting, maintain the total XYZ transform in a parent NiNode and keep the XYZ of the verts intact. When Merging, either:

A) Insert the bhkCollisionObject at the proper depth with the original XYZ vertex values.

B) Create a new bhkCollisionObject on the parent BSFadeNode, and compensate for the original parent transforms by adding the XYZ offset to the collision vertices.

The only other solution I guess would be to not move the collision in your 3D program under any circumstances. Then manually copy/pasting the collision back into the object without ChunkMerge.
