Hi, maybe its a silly thing but I cant find a fix.

When I have a scene with for example a cube and a plane and use the pathtracing engine I get aliasing artifacts in the contour of the objects that have "background" I mean, the objects that are with alpha.

any idea?

Hi, you need to save the render with alpha at 16 or 32bit for best results

You might also want to check the 'premultiply alpha' box in the camera imager tab. This fixes a lot of alpha issues for me

yeah! that was the premultiply alpha thing in the camera

thanks very much

No problem!
