Hi people. Just rendering a background image where I use a spotlight shining at the camera with volumetrics turned on (no lens flare though). I seem to be getting a weird problem on geometry edges (see image) where it looks as though there is no antialiasing happening. This happens no matter what AA settings I use. Oh, the geometry is transparent if that makes a difference.

Anyone had anything similar and found a work around? The only thing I can currently think of is to render larger than I need and squeeze back down, but this image is for A3 at 300dpi so I don't really fancy rendering it at A1 @ 300 dpi!!

Here's a sample of the affected area.

Cheers

Have you enabled Volumetric AA (it's a separate setting from normal AA)?

Erm...of course I did...erm...well...maybe I didn't...erm...oops :o

LOL... 10 years of Lightwave use and I've *never* had to push that little button!

Thank you Mylenium for pointing out my complete ineptitude ;) LOL!

And for saving me a week of rendering time :D
