Thanks,

it is a bit difficult to use the pebbles code.

It sometimes generates blck spots, when used with radiosity and together with
its normal via pigment_pattern.
Moreover you have to use a very low accuracy value io get the wanted effect -
here I used accuracy normal {... accuracy 0.001}. Render time is directly
related to the accuracy value here.
