antialias in Irrlicht only works for fullscreen windows using DX drivers. in theory, to use antialias you will need to use the IrrlichtDevice.createFromParams() instead of IrrlichtDevice.create(). you will need to pass an instance of SIrrlichtCreationParameters into the createFromParams() function. to create an instance use SIrrlichtCreationParameters.create(). you can then set the individual params on the SIrrlichtCreationParameters instance by using setPropName() methods where PropName is the name of the property you want to set. please see the Irrlicht manual for SIrrlichtCreationParameters to see the params you can set.now the reason i say "in theory" is because while researching this for you i found that i missed the antialias property of SIrrlichtCreationParameters when i wrote the wrapper i have them in now, but i have yet to build a new release. i will post here again when i do. should be in the next 24 hours.
