A bit of experimenting. Loaded the base figure and spot rendered, eyes look OK. Then clicked on materials and the eyes looked as in my attached screen shot. Tried adding materials again etc. but the eyes still render as per attached screenshot. It seems that the eyes render OK on the figure as first loaded, but then 'adding the materials' (which is how the Gen 8 Female works - I think, now I'm beginning to doubt my sanity) causes the problem. Seems rather odd. Getting confused...…
