Handle retina / non retina in 4.3

Hi all,

I'm importing multi resolution sprite assets from Texture packer. How do I in 4.3 switch different texture atlas depending on the device?

thanks

 

i've asked the same question here, someone replied "I believe the only options at the moment is to make a separate atlas for your hi-res sprites and reference that instead of the other one when you detect a retina device. "

Or you can do this (via 2Dtoolkit)...
