lattice deformation issue
There are 2 clusters:
TopClus has 1.0 weight for all lattice verts on top, and .5 for center verts.
BottomClus has 1.0 weight for all lattice verts on bottom, and .5 for center verts.
Each cluster has its own (zeroed) spline ClusCTRL that parent constrains it.
Both controls are parented under a (zeroed) MasterCTRL spline.
while at <<0,0,0>> the MasterCTRL can be moved or rotated and the lattice will move or rotate precisely with the control. Similarly, while at origin, the ClusCTRLs can be rotated and they work predictably.
Once I move MasterCTRL off of origin, say, <<0,0,10>>, translations start doubling on the center .5 weight verts. I say this for lack of a better way to describe it... translating the CTRL works fine, but if moved, THEN when I rotate it, the weighting is off.
The attached image has MasterCTRL.Translate = <<0,0,10>> and MasterCTRL.Rotate = <<0,45,0>>
As you can see, the center verts are kinda going bonkers. If Translate = <<0,0,0>> though, it would look like an unbent block simply rotated 45 degrees on the Y axis. Unbent is the desired result.
