In most cases where it has been shown to exist the derived McKay correspondence D(Y) -> D-G(C-n) can be written as a Fourier-Mukai transform which sends point sheaves of the crepant resolution Y to pure sheaves in D-G(C-n). We give a sufficient condition for E is an element of D-G(Y x C-n) to be the defining object of such a transform. We use it to construct the first example of the derived McKay correspondence for a non-projective crepant resolution of C-3/G. Along the way we extract more geometrical meaning out of the Intersection Theorem and learn to compute theta-stable families of G-constellations and their direct transforms.
