So with the level you have made, whats the smallest terrain detail you can make?
Well I think maybe CryEngine can do better one the actual Landscape plane, but the page I sent you is the Recomended sizes,
you can do higher but a map with bunch of objects in it this big will in the end have performance issues if going high detaled. At
the moment, the whole island is 1 map, if Ill keep it that way, no idea. IMO I think the landscape is plenty enaugh when it comes
to smaller detales but in the end its the materials and models that does the rest of the job for such as bigger rocks.
How is unreals terrain tools? are there many plants/vegatation available for it?
Well UDK gets patched every month which sais a lot about the engine, always fixing bugs, always adding new features so thats great. There are a bunch of free models, models which you also get when buying a license to sell ur game. But no, not a lot of tree's but the editor has all the features e.g. Unity has, paint out grass and trees and etc.
On the scripting side it's a bit different, there are two different ways, 1: Kismet, its a graphicle way to do scripting, can make a whole game by drawing lines between boxes, should check it out, it's awesome. It good for people with no intention of learning a language but yet want stuff work in game.
The other way, and the most safe way is just like any other engine, real classic scripting, in UDK (Unreal) it supports UnrealScript which is its own language. It may sound different but it's not, its based on Java script, I'm educated in C# and it didnt take long until I could write some basic stuff. So yeah, Unity supports C#, java and another one I cant remember but I dont think it would be hard to convert it into UnrealScript.
Any ways thanks a lot of the nice comments folks
