Lets make Lightmass EPIC (and understandable)

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.

I just wanna throw in my 2 cents. I’ve noticed that if I set all my Indirect Lighting Intensity to 3 and in World Settings under VR, set World to Meters to 1. Fills up the room with more light and looks great.

Works fine for me in 4.10.

Yes, Indirect Lighting Intensity really does help lit the room. I’m using it for Skylight only though, not every light source. However I’m curious with that VR Settings. Have you tried using Indirect Lighting Intensity without changing the VR Settings (leave it at 100)?

JOhnRose81 · November 22, 2015, 3:08pm

Yes. Absolutely. Not sure why it was such a big difference.

anonymous_user_6096f04f · November 22, 2015, 3:18pm

I’m not positive but I think it might be better to use the auto exposure settings in the post processing volume to adjust brightness. I think you lose less detail.

JOhnRose81 · November 22, 2015, 3:26pm

Right, but that doesn’t boost indirect lighting and reduce dirty walls and light leaks. But you ARE right by saying you lose less detail if you can balance out post process auto exposure and indirect light intensity.

anonymous_user_6096f04f · November 22, 2015, 4:47pm

Ahhh, I see. I used a ambient cubemap on one test with a .25 setting which helped clean up some dirt.

I noticed a problem with UE4 why the screenshot output is without AA and the images looks real bad. now I only use printscreen on the keyboard sad T_T
Working with lightmass definately give us some headache here I tested a very budget lightmass result.

Medium quality lightmass.
with SKylight+directlight
staticlighting scale must set to .2 to get good indirect shadows.

Does anyone have a copy of all the .ini default settings, I copied the ones in this thread but lost the default settings by mistake! I want to change them back to default for some testing.

Thanks!

anonymous_user_37d46923 · December 14, 2015, 6:15pm

Here you go.

The attached file is the default baselightmass, renamed as .txt since the .ini seems to be a problem for file attachment.
Just remove the .txt at the end and u’re done.

Yaaayyy… Thanks to @ for starting this post! And big thanks to @ for listening and implementing light portal!

edit: and for also integrating Intel Embree to UE light mass system, really can’t wait for UE4.11

heartlessphil · December 19, 2015, 9:09am

Incredible!

Portals and Embree for the win!

tupikp · December 19, 2015, 1:49pm

Well… UE 4.11 preview 1 is due next week, fingers crossed!
