Scene Effects

Scene Effects apply to entire rendered scene and are part of the Environment Effects dialog.

MSAA

Multi-Sample Anti-Alias is an effect that reduces appearance of jagged edges along adjacent polygons rendered on screen.  Anti-alias also reduces flickering that can occur between contrasting colors along polygon edges while the view is moving.

Settings
None: 1 sample, no MSAA
2x: 2 samples
4x: 4 samples (default)
8x: 8 samples


Higher sample count increases anti-alias effect for a better appearance.  MSAA places a higher demand on the GPU and can reduce frame rendering speeds.

Note: If frame rate is slow disabling MSAA may improve speed.
Note: MSAA 4x is default for new files.
