Another visualization using Unreal:


I had the opportunity to use Unreal for at least two visualizations and is not that difficult once you understand the correct workflow.

This on is really amazing. Love the mood so much!

The chalet scene is very cool! Makes me want to buy it (the chalet)! I've finished my New Tamayo museum scene with Corona and I'm going to bring it to ue4 and see if I can get something cool out of it. Congrats XOIO.

Yea nice find man! I was thinking about doing an art gallery. I think Ue4 is well suited for this type of stuff!

Concerning the UVw unwrapping, I found this maya 2015 video one of the best to learn about the subject. I might even add Maya 2015 to my workflow just to do my lightmaps.

Anyone have experience with 3ds max vs maya for uvw unwrapping? I heard quite a few times that Maya was better.

In the 4.5 version there's no need to unwrap anymore for lightmap UV's. At least that's what I've been reading

http://viscorbel.com/ue4-realtime-archviz/

So far I've been messing with Unity alot but the lack of making good lighting and shading is too limited and I sincerely hope that the 5.0 version will solve alot of those issues (If they ever release it...). I'll be giving Unreal 4.5 a go since alot of nice footage is coming out the last months.
If anyone has more footage or workflows for Unreal  I'd like to see those.

Yes but apparently the auto-generate lightmap sucks. I want to test 2 new features this week, distance field AO and distance field soft shadows!

By the way we are on 4.6.x and 4.7 is coming soon, they previewed it earlier this month. 2-3 weeks I think until it's out.

Recent Koola's environment tests are pretty good. Not sure if he use the 2 new features of ue 4.6 and 4.7 preview which are : really improved foliage instancing and Precomputed lighting and shadows are now supported on foliage objects and instanced meshes! This allows for very efficient rendering in scenes with stationary or static lights.

He made a gorgeous winter forest scene too, https://forums.unrealengine.com/showthread.php?58385-Koola-s-stuff

On a side note, I'm getting quite decent results with auto-generate uv lightmaps tonight. I've decided to break my asset into multiple parts in 3ds max, save in fbx, import fbx...in Ue4, cranked lighting settings, high res lighmaps (512-2048), 100 indirect light bounces, etc. This test is with a 12k polygon design connected chair, divided into 8 pieces. As you can see no artifacts or weird shadows



This second test using the auto-generate uv lightmaps, is a 67k triangle wall. lighting quality high for speed (instead of epic), lightmap only 1024! Ground is a brush.

You missunderstand these features, the important part is not soft shadows, but distance field ;- ) They are absolutely unsuitable for anything archviz oriented. It just sounds good on paper but when you study the examples a bit better,
you will see where this is actually applicable.

The forest scene looks so bad, like worse then CryEngine1 from 6 years. I don't get this, don't have time to test, but as great as interiors look, the foliage is abysmal.

I tested the features with LPV (yea I know, I gave it another try). Everything was bad like you said. Concerning the vegetation I think the main problem is speedtree...the quality isn't that great. I Wonder if it would be possible to use far better trees in 4.7 since they apparently improved the instancing and foliage performance!

On Stream they said ue4 is going to have a built-in grass feature...probably going to look too ''gamey'' but we'll see. But if I'm correct it's not going to be instances of grass patches but more like you'll be able to ''grow'' grass out of a selected surface.

Juraj, one day, if you find time, you should try to remake your Icelandic coastal house project in ue4. It could look very nice!!!

In summer I started to make the Kogan house (https://www.facebook.com/jurajtalcik.visualizations/photos/pb.167322623372220.-2207520000.1423826626./580794602025018/?type=1&theater )
in UE4, but the sheer amount of work and little time stopped me :- ) I will finish it though.....some day....

wow yeah, that one is totally different. The snow on trees and the effect....god that is beautiful. Reminds me of old rpg (MM-6) game where I first saw snowing in first person, it looked horrible by today standards but it left me deeply fascinated.

Neat little feature coming in 4.7 : Automatic Asset Importing!

Importing meshes, sounds and textures has never been easier. Simply save your source art files under your project’s Content folder, and the editor will automatically import the new files, ready to be used in UE4!
If you update these files from an external application, the editor will detect that and automatically reimport your content! This makes iterating on game content much faster.



Also, new dynamic G.I method that could come with 4.8 (currently experimental feature on github master branch). Here's a gif and the link to the discussion about it : https://forums.unrealengine.com/showthread.php?2421-Global-Illumination-alternatives/page6



Finally, on stream tomorrow... Tim Sweeney, co-founder of Epic Games (He has never shown is face on stream yet) will make  a big announcement!!! Can't wait to see the boss!
