Hi, As far as i found out, a DerivedMesh is created as soon as some modifier needs to construct its own geometry. There are the utility functions get_dm() and get_cddm() in MOD_util. What is their purpose? I looked at what they are doing and it looked like get_cddm() would ensure a DerivedMesh is created. But somehow it does not update the vertices and normals.
How im supposed to access the vertex normals that would exist after the last modifier worked on them, before my own modifier, if it is just a deform modifier, that does not deliver a new DerivedMesh? In other words: Can i update the DerivedMesh passed to deformVerts()? Or is there a better way to access the current normal data? Vertices seam not to be updated after get_dm() or get_cddm().
