Many thanks for all the replies.
I already have abarro, and yup it is very poly-heavy.

And the scene I have in mind requires not one but five or six willows. I 'spose I could always render them out singly (if I can get Bryce to swallow one) against a plain (contrasting colour) back-drop, use PSP to create an alpha-plane for transparencey (or a transmap, depending on what Bryce 5 can deal with - Bryce 3 can only handle .bmp's, I haven't exploered B5's import/export capabilities yet)...

Thx again,

Cheers,
Diolma
