What is Antialising?

[shak59]

Is this a typo or is it a special art term?

(File - Preferences - General - Antialising...)

[tekman]

it's to make the the art less blocky and more smooth, though that depends on your resolution, if the resolution is too low it looks pixelated instead.
it's actually spelt Anti-aliasing

Ha! That checkbox has been in Hexels for almost 4 years and no one ever mentioned that typo before! Thanks for letting us know! Should definitely be spelled antialiasing, which is a technique to make lines and edges look less pixelated.
