I've noticed some aliasing artifacts showing up in my render. I've tried even high levels of anti-aliasing, and changing from normal lights to hdri, etc and nothing seems to help. Any idea as to why these jaggies just refuse to disapear?

Oh those are just plain horrible :annoyed:

Have you tried rendering it at twice that size? What happens then?

Could there be some extra polygons or rings of two point polys in there?

I get the same feeling... but I'm new to LW, so I dont know how LW reacts to that situation although that's what it looks like to me.

Alright guys thanks. I remodeled the items from scratch and the artifacts have disapeared. I don't know what was the culprit, could have been those weird polys... At least it's fixed (for now).

This may not be a problems on THAT render,but....

If you use HDRI reflection images you could force LW to try to anti-alias between two pixels it can't. Going from a superbight (rgb = 100,000) to black with only one step between won't happen. That example would still give you a RGB of 50,000, still overblown white but technically anti-aliased.

It could be that remodeling gave a different angle on the edges and isn't picking it up. Just thought I'd throw that out there if it shows up again.

Using 'Limit Dynamic Range' usually clears up the problems CG.p just mentioned... (Under Image Processing Tab). :wavey:
