UDK vs Unity
show user profile  mike_renouf
I'm going to embark on something that I should have started a while ago.. learning how to use a game engine editor for archviz purposes.

I've taken a quick look at both UDK and Unity and both seem pretty cool. I was wondering if anyone has used both and can give me some pros and cons so I can make a choice which to pursue.

At the moment my attention has been grabbed by UDK because it seems to allow lightmap baking as standard, whereas this is a Unity Pro only feature (i.e. you can't have it for free in Unity, only in the paid version). I'd really like to bake lighting info into my scenes somehow (I gather some people do it using vray or mentalray even) to increase the realism. Apart from this I don't know of benefits or drawbacks that one system has over the other.

Looking forward to hearing some thoughts

create & apply your light maps in max. that's the config / workflow I've gone with anyhow.

the rest of it - will leave for those with experience of the engines you're interested in to comment on.

Usually I just monitor this forum but in this topic, I think I have something to say.

First of all, I am no expert in this area, but I have some experience.

I have done a lot of research on architectural visualization and found out that Unity is one of the easiest engines to use. I have been using it for 2 years in production for architectural visualization purpose.
I do not know about the UDK but I believe you can get the same result with both engines.

Here is the best result done by Tearte Digital Rendering in unity as far as I have found:

Everything in this video was baked with Vray.

My advice would be, the better arch viz artist you are ( I mean more experience), the better result you will get. Of course, you need to learn some special tricks and settings to get your model into unity. 95 percent of my time, I spend in max, and other 5 in unity.

There are some drawbacks to unity free version. Specially when you are making glass material or mirror. It is little bit tricky. With Pro version, you get a fancy glass shader. There are no real time shadows. You need to bake cubemaps in external software. Probably you have to do it in max.

This is just my experience in this matter. Hope it helps.

I've used UDK only, and what i can tell is that the documentation on it is HUGE, its easy to learn, that's a huge PRO.
Cry engine delivers photo-real images quite easy (Cryengine has no lightmaps at all), but for me it was harder to learn. If you want large open world scenes, like if you have to design a city or a whole street or maybe a campus (etc.) CryEngine would give great results in a short amount of time. For indoor scenes I've seen good results with all three.

PS: Using lightmaps in UDK is quite easy peasy, but generating good ones for photoreal stuff, i got no idea.
PS2:If you do choose UDK i will be willing to help you as much as i can to get started.

I have done stuff on both.
I think they are both the same in most areas.

I feel that the biggest difference is that they have a very different approach in their licencing.

UDK is free until you make a product that makes over 50k then you have to shower them with royalties.

Unity: needs to be purchased and then you also have to purchase sdk's for phones but I don't think you need to give high royalties.

Both are crazy expensive (around $80k) to get counsel rights if you get certified to do counsel games

I have used both. I'd reccomend the UDK over Unity any day of the week.

I've played with Unity. I liked it but am not apposed to trying out UDK.
I thought it could be useful for factory walk-throughs for some of my clients.
I wonder what the licensing will cost for something like that with UDK.

UDK licensing is simple.

You want to create a project? That'll cost you a grand total of $0.00. You want to sell this project to people? No problem. Your project starts earning you over $50,000 per annum, then the folk over at Unreal will ask you politely for a percentage of your earnings. You are, after all, using their engine. If you decline, they shelve your product and ban you from using their engine. You can also outright buy a floating, or multi-seat license for their engine too.

Unreal Engine 3 downloaded.

And I'm staring at the screen like a rooster watching a card trick.

Sounds like UDK is the one for me. I like the 3Dbuzz tutorials i watched on YouTube so far so I'll plough on with those.

Unity's interface looks a bit too much like a file manager and less like a graphic engine, though that's a minor thing. The big flaw in Unity - for me as a complete noob - is the one I suspected: reduced functionality unless you pay upfront. It'll take me months to learn it at the pace I have now (due to work and family commitments) so the free trial of pro will expire before I get to grips with "Pro Water" effects etc.

@Joey - I'm staring at it like a rabbit in the headlights mate.

This stuff may be a bit too advanced as you're just getting started, but both these scenes have downloadable files you can look at and have a nice arch-viz render style. Bookmark 'em for later. :)

UDK hands down. People like Unity because there is no learning curve, but its like giving your toddler a bouncy ball and suggesting he is a pro sports star.

If you want to make something decent, stick with a mainstream engine like UDK or cryEngine. The only con is that they need like %25 royalties. Although you might be able to get away with a single seat licence for 4K, which could work out cheaper.

He who says it cannot be done is interrupting the man doing it.

As I said to Clayton the other day on facebook:

UDK is like snorting a line of cocaine. Unity is like spending the day at a petting zoo with your four year old neice.
