Hi Terry, You can't flatten a static transform when anything it its subgraph is shared with other transforms, if you do flatten it the the object is the trying to be in two places at one time, something it can't do, what happens to these objects is undefined, in fact quite rightly disallowed

If you have a transform tree, with the following: A: translate (0, 10, 0) | ---B: translate( 0, 5, 0 ) | | | --- Model 1 | ---C: translate( 0, 20, 0 ) | --- Model 2 Then A cannot be flatten with B and C, because B != C. If A, B, and C were flattened into a single transform, then Model 1
