How to create fake light cones - 60 second Blender tutorial

Sometimes volumetrics are too slow for the result you are going for, in this tutorial i show you how to create fake volumetric light cones for a much quicker rendering.
How to make it work in EEVEE:
Change the cone materials blend mode to "alpha blend" and add a color ramp node after the subtract node.
Thanks to "Justin" to suggest this change!

Important: In the "light paths" tab you can find the "max bounces" settings.
Do increase the "max bounces" number if any black areas appear when using many light cones.

Pro tip: These light cones render noise free with only one sample.
You can render them on a separate render layer and add them in the compositor to save even more render time ;)

I guess Ian Hubert is breeding a new generation of very quick tutorial geniuses.

OMG thank you very much, I was trying to make some city lights that wouldn't be affected by distance like with volumetric.

It worked! Thank you for the tutorial :)
Just one thought... I know the video is supposed to be just one minute long, but in order to be really helpful, I think it might be better, if you not just explain what you are doing, but why you're doing it, so that the spectators learn how certain nodes really work :)

Hat funktioniert! Danke für das Tutorial :)
Nur ein Gedanke... Ich weiß, das Video soll nur eine Minute lang sein, aber um wirklich hilfreich zu sein, wäre es denke ich vielleicht besser, nicht nur zu erklären, was Du machst, sondern auch warum Du es machst, damit die Zuschauer lernen, wie bestimmte Nodes wirklich arbeiten :)

- "Volumetric denoiser artifacts hate this one trick!!"
Dude this is the best thing since the discovery of the fire!

[LanceMyair]

Dude! This is like the best control of volumetric like I ever had. So amazing! :-) Your are the hero of my day :-)

I only needed one video to get subscribed, your tutorials are perfect and honestly really useful

[maxgrey]

Awesome tutorial!! I've thought of doing this before but I never tried it because for some reason I assumed it wouldn't look very good, but you proved me wrong! It's perfect for some projects I have in mind

was trying so hard to see what i was doing wrong then i realized this is for cycles lol

[kontrastwesen]

saves a ton of render times compared to real volumetrics ♥ thx a lot

[JaniSuni]

I don't know why but it wasn't working for me at first. Then i swapped the shaders going into the Mix Shader node so that the Transparent BDSF Shader was going into the first input and the Emission shader into the second. Then it worked. I hope I can help someone out!

VIDEO: Don't forget to add...
I'M LIKE: Dude, what? Where the other nodes came from and what are they and why I don't have them? Also what you mean "don't forget to..." ? I'm here to learn it. How could I not-forget when I don't even know yet? :D

[AGrandeArte]

Congratulations for the video. You are God!!!!

[necropolix]

Thank you so much for this, i've been wondering how to do these for ages!

[TaitiTaitilil]

Thank you for this very useful tutorial!

[fabianeer]

This gave me a ton of new ideas. thanks a bunch!

[stanislovasm.]

WOW, thank You ! I were looking this couple of weeks, D Making scene where I want to make fake light beams.

[MirceaKitsune]

Pretty useful tips, thank you for sharing!

This is how animation 3D and 2D (hybrid) vehicles and street lights are done, I guess. I saw that being used in Transformers Cyberverse and I wondered how to create it with Blender 2.82a. Now I know. I tried following along but my results were not like in the tutorial. Maybe I did it wrong. Will try again!

Constructive criticism point - way too fast with the editing. need to slow down so we can follow it.

[rizzolini]

followed this tutorial to the letter but it doesn't seem to work
