Filter Forge - Weird Antialias artifacts

Active Topics Search

Zsolt Posts: 4	Seems like if I add the output of a refraction with a free gradient to another refraction, these weird artifacts appear on the AA pass. The lines coincide with the AA edges. Is there any remedy for this issue? Or should I just render super large and downsample to the final size, like poor man's AA?

Zsolt Posts: 4	Apparently the Blur is the issue. If you replace it with a Motion Blur with the Directional and Angle set to anything but 0 it doesn't do the artifacts — albeit it's not exactly the same result as a regular Blur. If you set to 0 it behaves as the regular blur and messes it up again. Seems like a proper application bug, like there's a division by zero somewhere.
