Title: Replace image in Atlas
Post by: ant on April 17, 2012, 10:09:59 AM

Hello,

Can i programmatically replace/add/remove an image within an Atlas? I'm requesting images from a server and would like to have them added to my main Atlas so to keep draw calls down, but ultimately keep transparency working as expected.

thanks,

Not as it is now, no.

You can make individual Materials and show them with a UITexture, but you can't put them in an atlas at run time. Yet. ;)

I remember there was a thread about this in the old forum. The old forum is still accessible, so it would be worth a look...If I find it I will post the link here for you...

It seems NGUI has no method to do this, the hack i came up with awhile ago was to write new pixels into the atlas texture myself (very slow)- i'll see if i can get this to work a lot faster. Thanks,
