Hi Rune, I was watching the Unity 2014 Advanced UI video and at aprox 45:09 in the stream you mentioned something about a system for swapping out graphics but I did not understand the acronyms you used. What were you referring to?
iByte
The only two acronyms i heard were
SD = standard definition
HD = high definition
referring to the image assets mainly. i.e. SD image might be 256x256 HD version of that same image might be 1024x1024
Ah thanks - that makes sense now - so I guess my real question what are the “plans” he was referring to?
He said “with the same plans we have going forward for supporting SD and HD assets swapping out images using that system …”
I’m not to sure what the exact plan is. Its something the 2D team have been dealing with so we were just going to wait for them to solve the issue. I’ll ping one of them to get back to you on this.
You can use Asset Bundles to create a SD/HD system for your project.
In Unity 5.0 we have updated the bundle system and it’ll be a lot easier to maintain.
Here’s a video of how to use the new bundles for SD/HD sprites:
We’re working on how to solve this by making it easier to do the sprite swap 
velipekka, I just finished watching your Unite 2014 video last night. I will watch this one too.
