Just tried the demo Epic Citadel that is Unreal 3 engine adapted to Ihpone on my Itouch 4 (3GS) !
Just amazing the quality the engine can bring on last Iphones !
Ok it had no characters, but big and detailled level with rocks, trees, castel, water cascade, animated trees, ambiant sounds ...
all smooth, with precise lightmaps that have some simuled HDR effects on some bright parts exposed to sun !

















But i think the cost to use it must not be cheap !
Well let's wait for some games made with this engine , it would be next level if 3D artist bring such good models and precise textures !

There has been a thread about it before (not sure if it was in Morbius or here).

About the price, as far as i know, the engine is free, like UDK, unless you earn more than 20k or whatever the limit is.

Though if i remember correct, the demo isn't THAT impressive cause everything is baked, even the specular, at least thats what i've read from other people who examined the demo.

How do you "bake" specularity?
The point where you see it moves with the camera... doesn't it?

As I see it there just is no specularity. Instead they feature parallax and normalmapping. And all together I consider this demo quite cool.

Does anyone know how to set the output settings? The demos seem to be set always to the highest settings - what, if I want to publish a version for android?
(Maybe, my version of UDK is too old? --> 2009_11)
EDIT: The last beta doesn't work for me.
AND: Sorry, I should look myself: the Android 'export' isn't even implemented!

Even baked, the lightmaps are great quality !
The engine allow vast and beautifull scenes.
Unreal engine allow to manage lot of polygons in the scene, just look at rocks, or rounded corners on the city !
And there is a room with reflections and special effects, but well let's wit for a talented team to make a game using Uneal 3 engine for iphone to see what it can really do !

I recognize some others engines have also lot of power on Iphone !
I played the last FPS from Gameloft on Iphone 4, just amazing the quality. i've remarked they have used good optimisations like the use of 3 LOD for characters for example, it allow sprecise characters for an Iphone when your are near, and to have 5,6 or more ennemies at same time at screen !
The animations of weapons, sounds, precise textures all for an Iphone is top quality, lot better than any FPS on PSP for example.
Even more i didn't find any time on 3DGS some FPS demo as good as that game on Iphone !!







The big advantage of Iphone or Android, is the price for such quality games. On PSP or NDS that's lot more !

In fact on the las picture showing Unreal 3 on Iphone posted above, we can see a good amount of polygons, only towers use a lot already.
When you see games on Iphone, there are less polygons use than that scene. I think it have big optimisations indeed, theyv'e done a great job for Iphone.

I don't know when will Unreal Kits for Iphone will be delivered
and what will be the price, i think it will be lot more than Unity.

Let's wait for dev kits and a game.

I suspect they use billboarding a lot. In the last picture the towers in the background and the church look like billboards.

I think that only the towers roofs are billboards. Everything else are just great texture, good lighting and models with few, well placed polygons.
I don´t think that they use any LOD, but instead they have choosen an environment which is perfect for some good occlusion culling. The view of the two last screenshots btw aren´t running completely fluent on my iPhone 3GS. There also aren´t that many different textures used, which is good to save draw calls. Well in the end they even seem to have enough speed left, which they seem to spend into antialiasing.
