wimvdb,

Aha!  No, no one mentioned that before, but enabling raytracing and the number of bounces - has certainly made a difference.

(I was already rendering with firefly)

This:

is better but the colour is rather more faded than I'd like and the black 'scrawlings' are no longer black and are indistinct.

ima70's result still has the colours bright as well as the glossy reflective look of glass, I'd like to get a bit closer to that if possible.

Is there anything else I should have enabled?
