Lets make Lightmass EPIC (and understandable)

[aviel08]

Oh no way! it is faster, just like you promised Dan, you're the man!

Well, Substance Designer plugin does not work, yet, in UE 4.11 preview 1, so can't test the rendering properly since my projects are using SD quite extensively. But yes, the rendering is pretty fast now and using less memory. Anybody knows how to activate/use the light portals?

edit: found it. Lightmass portal is in All Classes tab

Some tests...

Nice. Look how fast Intel's Embree is . Could you make a test without touching baselightmass.ini file? So it will clearly shows the difference between versions using only default .ini setups.

Are portals bi-directional or is there a front/back, and is there any portal related settings?

DanielW thank you so much!!!!! You have made a revolution for real-time arhviz!!!!!!!!!
This saves time.

This new speed is just insane! This basically allows to double quality at the previous bake time, Jesus Christ *o*

Wow, this is fantastic news! Outstanding effort, Daniel Wright and all the people who has participated in this thread.

Can't wait to play with the 4.11 preview. One question though - I assume that we need to re-think the optimal Lightmass settings now?

AFAIK, from Daniel explanation in the video, light mass portal don't need to have settings other than scale, since they are more like light mass importance volume, to force light mass calculation to focus on more important places rather than firing photons to every direction.

And I also would like to know if a light portal is bi-directional or not. Although from my limited testing it seems that light portal is working on one direction only.

Can someone tell me where to find the portal lights in the UI please? Can't find it.
Also, would be great to have a little run down on what settings has to be used to get the best results now with this new 4.11 release.

Thanks
Stan

You can find Lightmass Portal in All Classes tab. The best thing about UE 4.11 preview 1 is that I don't need to mess around with baselightmass.ini file anymore. In Lightmass setting, I rarely use high indirect bounce values, mostly around 10-30. Using low light scale such as below 0.5 also won't tax light building as high as in previous versions. Thanks to Intel Embree integration. It really helps and makes light building much, much faster.

However, don't use UE 4.11 preview 1 for your real project yet. The official release of UE 4.11 is February 2016.

I could use some help or advice, I started a new scene and wanted to take advantage of the portals in 4.11, but I'm getting a soft dark areas around each corner, even with different lighting. It looks unnatural and is the same even on the walls with the windows and the opposite walls. Any idea whats causing it or how to improve it?

Zacd, did you turn off all AO settings? I don't think what you have looks bad personally...

[ZacD]

I'm dumb, forgot to turn off post process AO.
