Try to ignore the ground..  ;-S
Progress is slow. I need to find a better way to show the veins on the 
leaves.

Comments and help welcome.

    It's not tall enough! ;) That's looking very good. How have you modelled 
the leaves?

Thanks :)

I first drew the edge of the leaf in CorelDraw in bezier curves. I then 
looked at the mouse coordinates when I hovered over each node and used those 
coordinates for the bezier patch.

I used quilted textures within scaled quilted textures for the veins and 
applied shear-trans to each smaller one to try and get a branch effect, but 
that doesn't seem to work.

     Hmm, it renders with holes in the petals with 3.5, 3.6 is fine though. 
I'm not at all familiar with the way that you did this, but my first thought 
was can you not go back to CorelDraw and remodel the leaves with the leaf 
veins added too? Would that not work?

I used 3.6. Its the filter transparency I used to try and simulate 
translucency

Working on a 500mhz ThinkPad it does slow things down a bit. so I'm worried 
that such a large amount of patches will slow down Pov too much.

Maybe someone in this group knows of a function that I can use as a pigment 
function instead?   {=')

Maybe try the crackle pattern? But it might be too asymmetric.
