All other unity tutorials should strive to this standard

[akmalsalikhov]

Best tutorial I've ever seen on Lightmapping. Thank you, Ciro! By the way, you have a great voice and I would love to see and hear more tutorials from you!

[pratyushbarikdev]

This is the best video on lighting so far.

[tiredlocke]

I've read and I've watched and I've played around with lighting for a long time...
Several concepts finally just "clicked". Thank you!

Now I'm off to do some baking!

[ShackMan]

One of the best Unity tutorials I have ever seen! This will result in less headaches for devs and better looking games for everyone. Thank you!

[pixelscholar]

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 YouTube 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!

This is pure gold! A single video can convey so much more than countless pages of documents

[MrWetwilly]

This is an essential tutorial, i cant believe I didnt notice it on unitylearn or some other place

[LloydVincent]

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]

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!

[ericmonnereau]

The most best and detailed tutorial of lights in urp. Now i need tu put this in my game! Thanks Ciro!

[WidmerNoel]

I wish I would have found this earlier. This clears up so many things for me. Thanks a lot!

[D-Dev]

One of the best Unite Now videos, and one of the best video about light mapping.

[evanlane]

What a fantastic talk! Thank you Ciro. This has helped clear up a lot of Unity's numerous settings.

[brianfromearthhh]

Thank you so much for this! We need more in depth URP tutorials

[BabbSteve]

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.)

[dewlorr]

Excellent tutorial! Easily the best one i have seen so far for Unity lighting .

[bsorochka]

Awesome Tutorial, I wish I had come across this when it was first released. Great speaking voice. The organization of topics/presentation flow was also fantastic. Thanks!

[expansevr]

Fantastic breakdown on lightmapping. Great work Ciro and Unity Team!

[chriswatts]

Very well explained ! Please more of this type of video!
