hey, I have the same impression, I’m testing it on an ipod touch 5 generation with IOS version 6.1.3, Epic Citadel Unreal Engine 3 looks great. but the mobile base that is in the market place such as is mentioned Alex Man, at a resolution of 5??x3?? we need to configure?.
Yea I was impressed by Epic Citadel as well and decided to give UDK a go after downloaded that. I was a Unity 3D user and want to switch to UDK because of the level of effect and quality that UDK can do.
Have you tried their “Mobile Temple” sample project in UDK4? I built it on iPhone5 and the effects and quality is not as good as what I can see in my Macbook Air as well, my Macbook Air is just using Intel HD5000 integrated graphic, no dedicated graphic card.
Which makes me think that there must be some settings that I had missed, in Unity 3D what we do is simply just 2 clicks to set everything like texture level, shadow, AA for any mobile platform ( attached 4.png ). I hope there is something similar to this in UDK4 here, just I don’t know where it is.
Okay - i investigate…
Its an important topic for my self too…
The Mobile demo on Marketplace though… only compiles on iPhone 5S/iPad Air/Mini (A7) it seems… and i haven’t found a way to get it run on iPhone 5 yet. But i would like scaling up or down like that… so i build one thing to deploy on multiple devices
I think the Renderer are fundamentally different… while the UDK (UE3) used shader in a more traditional way, to generate the desired look (Shader that aim to look like real world materials but cheat) the new renderer uses ‘physically correct shader’ like modern renderer do (such as Arnold or even Blender Cycles) - that implies that to make something reflect its not longer a just a “gl_buffer” call - I guess its also quite difficult to generate the UE3 look because everything there is just good art direction and a cheat.
Basically you copy out the contents of Config/DefaultDeviceProfiles.ini out of the Tappy Chicken demo into your Config/DefaultDeviceProfiles.ini - in my case it was the mobile demo. Launch the game on your iPhone/iPad and now you have a retina version.
