Transparencies.... grrrrr

[Lamont]

The image below is the problem I am having. Raytraced trans/shadows is on... going nuts here. One area light and a "sun" (distant light from sky-tracer2). Ground fog and haze. I just get this stupid halo around stuff. Cropped from 2000x2000.

LW v9 (not beta)
WinXP64 Pro
4GB ram

Compositing isn't an option because this is a benchmark scene.

Are you using a clip map or a transparency map? Just wondering because the title suggests that you are using transparencies instead of clip maps, but either way there seems to be a definite problem with the render. I think that an issue like this came up in the beta as well and was fixed, so maybe it's been a problem since 9.

Using a transparency map.

Just my luck ;) I'll muck with some settings.

Switched to clip maps and the problem went away. Not only did it go away, but the render times dropped 96%. I can only guess is that the leaves aren't alpha-blended anymore.

Glad to be of service :)
