EyeonTips:Manual/Tool Reference/3D/Renderer 3D
From VFXPedia
In certain situations the 3d render will produce strange aliasing or "jaggies" to prevent this effect set the 3drender nodes image size to at least double your needed resolution then directly after the render node pipe in a ResizeResize tool and scale down to your need size.
For example if your resulting comp is 720 by 486 you would set the render node image size to at least 1440 by 972.
Limitations
Currently the Renderer can not render particles using the Line style in software mode. They do render using OpenGL.
