Lets make Lightmass EPIC (and understandable)

I suppose that lightmass doesnt have to be improved for the moment (and indeed isnt part of the release notes for 4.10). One nice addition to expect will be light portals from , maybe in 4.11.

After that, we can throw Vray out of the window

I’m not convinced about that. I still see some things to overcome such as reflections and better material shaders. One of the weak links I see in a lot of the images is great materials and reflections and I’ve seen most of the great UE4 users work.

I need your help guys, I’m confused regarding the skylight and sun light, to get better results should I use both together like in vray with the hdri dome and vray sun ?

Can’t be that. Walls have 256 and ceiling 512.

I’m pretty sure it’s something in lightmass, I just can’t figure which setting would affect this.

This build is done using medium quality with .4 scale , 100 bounces, 1 indirect quality and 1 smoothness.

Lightmass.ini:

NumHemisphereSamples=128
NumIrradianceCalculationPhotons=4096
IndirectPhotonDensity=6000
IndirectIrradiancePhotonDensity=3000
IndirectPhotonSearchDistance=180

I’ve had the same result on a previous production build with 512 hemisphere samples, 12000 and 8000 PhotonDensity.

Were you able to solve this?
If yes, Can you let us know how you solved it?

It depends on what you want to achieve. Start with a base skylight+hdri all the time. If it’s an overcast day, leave it as is. If it’s a sunny day add a directional light. Skylight is fill light, Global illumination…you need it.

Not yet, I have to finish another project before going back to this. When that happens I will make a new topic so we don’t overflow this one.

Has anyone figured out how to rotate the hdri used to light the scene? Is it possible to also have a visual representation of the hdri’s orientation for better adjustments?

I am too still looking for options to rotate cubemap in SkyLight, meanwhile here is the workflow to rotate HDRI which has been used in EditorSkyshere as a background.

I am working extensively for creating a tutorial which will cover complete Lighting Workflow for Arch-Viz (Exteriors and Interiors) in Unreal Engine. Will start updating my blog soon. Thinking of making video tutorials also, but little bit reluctant about that (shyness).

Very handy, thank you .
I’m looking forward to read your tutorial !

Looking pretty good man, thx for sharing

Try blueprints BP_LightStudio, which is in the Starter Content.
I changed it a little bit

Preview BaseLigntmass.ini settings from : MEGA
Screenshots:

1. disabled PrevisArrow
   
   
   
   2)Switch SkyLight 1 static

   4)Sun used separately
   
   
   
   5)Disabled Atmosphere and fog

Those look pretty good, thanks for sharing. I see aliasing on the shadows in some shots, any way to fix that?

[AE_3DFX]

i wonder how this can help archviz creators in future, i know that baking still has highest quality but still…

It’s normal it’s the editor view and screenshots (low res).

I got the same aliasing on lights when I exported a matinee sequence. Any clues why that is? It was on the actual light being cast on an object.

[heartlessphil]

That’s because his lightmaps are too low res… The floor is way too big for 1 lightmap.

So is this working for rotating the hdri that bakes the light? Or just for visual/rendering?

I would like to be able to rotate the hdri in such way that the sun on it is positioned where I have the most light coming through my indoors. ( not for visual but for getting the most light come through when baking).

[anonymous_user_6096f04f]

Mihanix. I downloaded your scene but when I open it in UE4 - 4.8 there are no assets in the folders, yet they are in the root folders. For some reason they’re not showing up in the import dialog either.
Any clues?

I used UE4 - 4.10 it may be the reason.

I’m trying to figure out how to do it. Very bad I understand in blueprints.
