Hi Mark :In the meantime, here's more ivy: http://www.xs4all.nl/~ath8n0r/div/IVYladder04.jpgLooks good . What kinds of render times with and without Gi ?
This one was about half an hour on a dual core 3GHz machine, haven't tried GI yet: that would devastate the render times. Actually, the ladder is dragging it down more than the ivy thanks to the blurred aluminium. I think a modest-sized ivy can be added to any outdoor scene without taking too heavy a toll on render times. Maybe the biggest danger is that it's too good: the contrast with non-ivy plants in the scene can be painful ;)
Yes , translucency is key and a real treat to look at under certain lighting conditions , I think . Does the paper shader parts allow you to vary the amount of transL ?
I made a few modifications that allow adjustment of the translucent color: see attachment. Of course, you'll have to download the textures from the Ivy site http://graphics.uni-konstanz.de/~luft/ivy_generator/ and redirect them.
Ideally, the texture itself should shine through instead of a constant illumination, but that's only visible in close close-ups anyway.
Incidentally, I overlooked the programmer's warning: "Please take care for the leaf orientation - in most renderings I have seen the ivy leaves are mapped upside down!" so yeah, invert V when importing.
Thanks for the feedback, Mark H
