Fantastic talk! Thank you for such fundamental explanations - very well done. Cheers! **Quick note for folks who are getting noisy light bakes even with high settings, go to Project Settings > Player > Other Settings Section > Lightmap Encoding > set to 'High Quality.' I was getting really bad bakes and it took a few minutes to figure that out. Maybe a note to Unity, but having the default of that setting at 'Low' produces very unwanted default behavior. As a artist with so many settings already, a bad default one causes frustration. Turn that sucker up, please. :) :) (Maybe this was mentioned in the talk and I didn't notice it.)

@pixelscholar 3 года назад

By far the most coherent and well organized video that your team has ever produced on the topic of lighting in Unity. Nice job! My team made the switch from rendering animations using 3DS Max to real time rendering using Unity about a year ago and I've spent the past several months running down the best tutorials on the topic of lighting and the URP on RU-vid as well as several paid tutorial sites. This video is the clearest and most comprehensive by far and watching it really made me feel as though I've finally reached a cohesive understanding of the process and the underlying logic. Thanks and keep up the good work!

@LloydVincent11 4 года назад

Fantastic video. I think most people who make tutorial videos don't have a confident grasp on this subject so it always gets ignored or glossed over. It's great to finally get some solid info and explanations.

@CaseyHofland 4 года назад

Thanks for this video! Save for understanding the relation between static objects and baked lighting, I have never known what I was doing when it came to the lightmapper. This was a really clear in-depth explanation with a lot of tricks that I'll be sure to apply to that sweet "performance by default" workflow!

Amazing tutorial and thank you very much for this. I have one question for now, because I haven't finished it yet. In 18:54 you start explaining how the lightmapping works and my question is this: You say that texel is shooting rays that try to find the directional light or environment light etc. It should not work the opposite way, where the directional light or the environment or any other light source is casting light rays that our bouncing on the geometry and are captured on the lightmap? This is what I have understand from other tutorials as well, and also, this is what I know from other software as well (Mental Ray, Arnold, Keyshot, Marmoset etc) Looking forward to your answer and thanx again for this great tutorial

Great video. Any hints to when we might expect more dynamic lighting features to replace Enlighten? It's very frustrating wanting to release a future game on many platforms with URP but also have a day and night cycle. Good lighting is pretty non existent for such dynamic lighting currently in URP.

just wondering what is the main difference between a regular 3D template from Unity and its Lightmapper tools/settings are and the URP's Lightmapper/tools/settings. I've noticed a few similarities , is there any difference at all??

What if I want to use more than 8 lights in one scene with urp ? The light pixel count is limited to 8. Should I switch to srp ?

@DonutGuy640 Год назад

I get the sense that I could use reflection probes, or maybe light probes, to make an unlit, subterranean room very dark. Someone please correct me if I'm wrong. Just to mess around with it though, and get a feel for it, I've created a reflection probe enclosing the central room in the FPS Microgame Learning Template, and can't tell that it is having any effect whatsoever.

Having baked lights and the shadows are cast, what will happen to the shadows when there is wind in the scene and the vegetation moves ? Will the shadows reflect the vegetation movement ? Thank you !

Shadows in baked lights are directly painted in the texture and cant be moved, so no

@TYNEPUNK 3 года назад

Great video, sometimes you sound Welsh somehow :)

@magellan124 3 года назад

Why does the lightmapper cast from the objects in the scene to the light rather than the other way around? Thats how photons work right? It seems like it would be less computationally expensive to do it that way. I am sure that there is some good reason for this, I just don't understand it. I don't have an engineering background.

@khoing1111 3 года назад

well, it is the opposite. If you cast a small number of rays from the light source, there are good chances it will not reach the pixel you want to calculate the light on (Unless you use millions of rays which will take ages). Not to mention, a lot of rays will be wasted if it does not reach any geometry at all or reach one that has lower resolution that we don't care about.

@mowax74 2 года назад

Very good talk. But your explanation of the light bounces when baking around 20:10 does not make too much sense to me. I think it's the other way around. The rays are not shot from a texel point on the surface to the light source. They are shot from the light source to the surface point. The lightmap texel on that point gets lit. Then, the ray color samples a little bit from the surface color to the ray color, and bounces back, hopefully hitting another surface point. This new texel gets lit with the new color from the ray, samples some surface color to it again, and the game continues till the number of bounces is reached. The more bounces, the more you get rid of those unnatural dark corners, even when the ray with this 4th bounce does not have that much of energy left.

@jeronimocollares320 2 года назад

Better solution to bake lights: change to Unreal. Unity is full of bugs in bake management, already reported in the community (which Unity doesn't READ and if it DOES READ, it just ignores).
