Hi !

I wanted to test if i can do some “vray style” interior.
Here’s my first test, i dont really like to model/uv stuffs so it’s pretty simple.

! You pretty much nailed it.

Is it a single directional light with a skylight or did you have additional spotlights at the window?

Looks great , as i am architectural visualization artist by myself i admit that you did great work baking that lighting in. That was a lot of unwrapping, eh ?

Thx !

For the lighting i have a spot that light a white quad at the exterior of the window (so no direct light/shadow, just smooth indirect lighting) and a directional for the sun.
I have also tweak the BaseLightmass.ini with totally overkill values^^.

And yeah, I dream of a “make perfect UV2” button

Here’s another quick light test with just the spot/reflector :

Aha! So you tweaked the .INI file, you sneaky . Seriously beautiful though. How long does it take you to build the lighting for scene?

It take less than 10min on a i7-3770.

My jaw keeps dropping as you keep posting these. :eek: You should record a video next time!

anonymous_user_138c2332 · August 11, 2014, 11:18pm

wow…most realistic render I’ve seen from a game engine. Your work is amazing, have you got any short video walk through from those 2 last scenes?

anonymous_user_a41f46e2 · August 12, 2014, 6:55am

looks !
Very well done!

AlwysAnrchy · August 12, 2014, 12:28pm

WOW! is fantastic! Great job . I know it keeps being said but I hope you are going to show us a video soon. Keep up the superb work!

Here’s a quick video
(First time I use Matinee, very cool and simple tool)

Seriously, the more I use engine, the more I love it ! Great job UE guys

HOLEE ****~!

O_O

Super-fantastic. Bravo. Simply genius!

deserves to be showcased by EPIC.

Madness, is madness…

Btw what tweaks have you done in BaseLightmass.ini to get crazy good results?

anonymous_user_adcf0aef · August 12, 2014, 9:05pm

Oh my flippity flippin’ freaking gosh. is the best architecture project I’ve seen made with Unreal Engine 4. #madskillz

SE_JonF · August 12, 2014, 10:24pm

Beautiful work!

TomShannon · August 12, 2014, 11:02pm

Couple of questions:

can you detail what you did to your Lightmass.ini? would be invaluable for the arch-viz community to work from.
Did you capture the video directly using FRAP/Banidicam, etc? Or did you use the in-engine movie capture?

koola · August 12, 2014, 11:37pm

Hey, thanks everybody !

For the BaseLightmass.ini I use values (and I almost have no idea what each value does^^ … it’s totally random)


[DevOptions.StaticLightingProductionQuality]
NumShadowRaysScale=32
NumPenumbraShadowRaysScale=64
ApproximateHighResTexelsPerMaxTransitionDistanceScale=9
MinDistanceFieldUpsampleFactor=7
NumHemisphereSamplesScale=64
NumImportanceSearchPhotonsScale=6
NumDirectPhotonsScale=32
DirectPhotonSearchDistanceScale=.5
NumIndirectPhotonPathsScale=32
NumIndirectPhotonsScale=64
NumIndirectIrradiancePhotonsScale=32
RecordRadiusScaleScale=.45
InterpolationMaxAngleScale=.75
IrradianceCacheSmoothFactor=.75
NumAdaptiveRefinementLevels=3
AdaptiveBrightnessThresholdScale=.25
AdaptiveFirstBouncePhotonConeAngleScale=2.5

I capture the video directly with the movie capture tool in Matinee.
