To show the necessity to import directly pvr file in unity, I’m doing this test.
Unity 3 final need a PVRTC Asset import, for offer the best quality.

Test 1
Test 2
This is disappointing. I was hoping Unity would take care of this for me without me having to take to time to convert every texture, then to boot re-link all the new pvrc textures to the correct materials.
Or at the very least, buy out the PVRTexttool guy 
I’ve been wanting custom importing of compressed textures and custom mipmaps for a while now, since a huge gripe people have when working with the iphone is about image quality.
no need to buy out anything, its enough if the pvr texture format is supported.
also buying out the pvrtextool is a few 0 at the end of the price too high for unity (imagination technology could eat unity, not vice versa)
Looks like we may be getting some additional texture pipeline options in a couple months. 
I don’t see anything in the Substance engine about PVRTC stuff, but at least they are thinking about texture-related engine updates.
the primarily interesting aspect on it is the note of nov
given that Unity 3.0 will likely happen around the beginning of oct I think we can be pretty sure that his date is not correct at all as such a major new feature would mean Unity 3.1 unless it happens as an extra license of some kind like the caching. (it can’t be in 3.0 as its not even present in Release Candidate 1)
Going to add this, from higgyb’s facebook:
In the upper right hand corner there is a scene shot of what appears to be Allegorithmic already in Unity. It looks like its in in motion!
http://www.allegorithmic.com/?PAGE=NEWS
No, looks like it will happen soon. This from the Allegorithmic News Page…
“This will be available to all Unity 3 users later this year, free of charge. Stay tuned for more info on this unique partnership!”
Strange to see the same page mentions Shiva agreed to this four days earlier!!!
Crazy times, but great times!

Men this is a super surprise… they didn’t announce it anywere, did they?
naw but thats not too uncommon. business level news happen everywhere but here for an undefined amount of time.
half the features for U3 took “forever” to be announced here, some are still not on the page for example but were already pre summer on the gamasutra news for example
Allegorithmic work only for PC, Xbox360 and ps3. Not on iPhone… I think
But it’s a good thing 
Hey hey !!! Good news …
Err, what? Where does it say it only works on those platforms?
Was mentioned somewhere that it will bake in for platforms where it can’t run.
so you don’t lose the texture but the saved space on disk (keep in mind, on vram it has always the full size independent of the tech)
as for pvr in unity vs tool: U3 allows you to drop in pvr textures
Is that in response to me?
half, yes
half is in relation to the thread on its own
Oh, I misread…
Hi, I know this is an old thread but I just downloaded the pvrTexTool. How do I even use it? There’s a photoshop plugin but it’s only for Windows. But I just saw the GUI version. How do actually put it in Unity iOS? Usually when building a project, it will rebuild the textures again.
*EDIT: Nevermind, just realised the built-in compression version in Unity 3.0 is already fine.

the built in compression of unity 3.0 is not already fine. The tool does a better job on alpha pvr
