I have not expressed any opinion on lumion because I don't know, I just said that to me with unreal engine achieves excellent results but for comparison you have to use both at high levels.
I don't use luminion but Unreal engine for me have a great power an you can push to a great result. It's vast program and depends by your knowledge to determine if and easy or difficult to use, but the results pay.
may i ask you that among unreal engine and lumion (which also include free version) which one is better choice? i haven't tried unreal engine and lumion is perfectly fast and easy to use but i am curious about unreal engine and i want to ask a pro user
