The quality of the renders can be adjusted by changing the Anti-Aliasing method. A different one can be selected for the 3D Viewport, viewport rendering and for final rendering.
The setting for the 3D Viewport is a user preference to specify the anti-aliasing method that runs best on the used system. The setting for viewport rendering and final rendering is saved per scene.
- No Anti-Aliasing
With this option selected no anti-aliasing will be applied.
- Single Pass Anti-Aliasing
Scene will be rendered with a post-process anti-aliasing pass.
The scene will be rendered multiple times with a slight offset. The anti-aliasing will be gathered from the multiple renders. The number of samples are predefined so it uses the best distribution of the samples.
5, 8, 11, 16, 32
Multisample anti-aliasing is well suited for rendering small details like hair.
Progressive Viewport Rendering
For the 3D Viewport, one sample is rendered at a time. When there are no changes to the scene or viewport the next sample will be rendered.
