Dear All

I do a lot of outdoor bridge renders and am looking to produce 'technical drawn' renders- basically toon style line renders with monochrome materials and edges inked in (differing thickness as per engineering drawings - I am a structural engineer btw).

I want to investigate the possibility of using billboard style tree models, rather than having lots of low polygon res trees in the background of my scene but I need these billboards to render in a toon style with the outlines inked in and that is all. I can create toon style materials for the bridge, piers, handrails etc. but am struggling with the trees.

I can create a standard billboard style tree using mental ray architecture & design material with the diffuse color material set to my RGB jpg tree and the cutout map with the alpha tree.

Any suggestions?

Kind regards
