"cracks" appearing during morphing
when morphing, I notice what appear to be 'cracks' showing momentarily in the surface of the object. On closer inspection, I can see through the cracks. This makes me suspect that the normals have flipped at the crack locations or something like that.
Has anytone experienced anything similar? If so, how did you resolve it? Should I be generating normals at every stage of the morph - surely that's impractical.
I would be very grateful for any help.
