Volumetric Lighting in ROBLOX and How I Created It
A showcase of a volumetric lighting technique in ROBLOX that I figured out how to do years ago. This is done entirely within ROBLOX and is a relatively basic technique.
Performance:
For me it runs at 60FPS in-game, but obviously results will vary depending computing power and a number of other factors, like density between the beams, the range of the beam box, whether there is proper camera culling, scene complexity, etc.
PC specs:
i5-7600k @ 3.80GHz
GTX 1060 6GB
16GB DDR4 ram @ 2400MHz
0:00 Introduction
1:50 The concept
4:58 Connecting it to the camera
5:31 Potential optimizations
6:11 Removing excessive beams
7:13 Mitigating artifacts
7:56 Lights
8:18 Caustics prototype

why it won't work for me?
could you let us download the showcase place, i was struggling with getting it setup and want to see what i did wrong
I suggest limiting the max distance for zooming out and attaching that to humanoid so it culls.
999+ missed calls from Roblox
bruh
are you able to share the place file?
@@ChaseDJ549 I will not be sharing the place file. I made a free model available, though, which is provided in the pinned comment
hi, im having a problem with the beams being very bright
@@inertians6452 if the beams are too bright, it's likely because they aren't transparent enough
Cool to know but not really useable.This looks good only under specific scenarios and theres way better options to do something very similar.

This is actually so genius!!! I’m gonna try it out 🤯 thank youuuu
Didn't work for me :( and I can't find any other tutorials other than this
I have a free model posted in the pinned comment, if you're having a hard time you can check it out to see how it works
does volumetric lighting still look good with the moon? since im currently trying to make a realistic horror game.
@@Spidxiooo yeah, it looks good at night, too
This map is free ? I see everywhere 😅
its because its the map called "Crossroads" its one of the first Classic roblox Maps
@@TigerPlaysRbx52923 how to get this ?
i did it and my sun wont stop moving
Beautiful, I love it.
Did you change your thumbnail? I think this is the video i've been searching for week!?!?
@TelaGamer yeah, I changed the thumbnail a little while back. Before it was just a screenshot
this is worst way to do that due performance
Yo this is super cool❤ wish you luck on youtube😊
oh i figured this out on accident a while ago
I have a new technique that kinda optimises it, if you go into blender, get the shape you want a volumetric cloud/fog, give it a particle system, make an icosphere, set the “render as” in the particle system to “object” then pick the icosphere, and under source, set “emit from” to “volume”, then change “jittered” to “random”, mess around with size then apply the particle system. Select all icospheres (except the first one) and join them with ctrl+j, decimate with triangulate till face count is below 10,000, then set a displacement and set it to whatever displacement texture you want and mess around, then go to “edit normals” modifier and give it weird normals (fixing the bottom shaded part) and then import to Roblox, give it a fancy transparent pbr texture and mess with transparency and yeah, that would also work with pointlights.
Does the volumetric lighting makes the game lag a bit more?
@@BS_lore57 yes
you can do this with parts (baking fake light) and the lightray feature in lighting
Did you even watch the video? Sunrays were mentioned but it looks much worse than volumetric light
autism is a super power
Most users on ROBLOX don't even have the power to run this lol Very cool though u earned a sub!
he was making this while dr disrespect was getting freaky
Honeslty man, this is great. For a game engine that was an old version of unity to its own engine that doesn't look great, this it cool
im guessing this would tank on about 90% of computers
@@mahuba2553 as long as your PC is decently powerful it can run it, my PC uses parts from 2016 and it runs fine
OHH MY PCCCCC
no way this dude did volumetric lighting and caustics accidently. this is actually top ten 999iq plays
wtf is that in the thumbnail? gm_construct?
@@Asarchi the thumbnail is from the showcase place that is linked in the pinned comment
so just letting eveyone know when future is bright 3 was in beta this same effect could be used with point lights, so lanterns and stuff could cast shadows like in this video. unfortunatly it was patched out, and now it only works for sunlight
gatekeeping an effect for 6 years... man
That's actually crazy LOL You really did that without coding anything, congrats!!
Theres no literal way he was starting with layered water
When you're in first person, do you see your characters shadow, that was another issue I found with stock lighting
@edwardkoziol5697 no, the character shadow is still invisible in first person. There are free scripts to make your shadow visible in first person, though, which look pretty cool with the volumetric lighting
@@RocketShotgun Oh, nvm THANKS!
Guys, this is the future
can you make a cathedral with gothic architecture with the windows with those rays?
An awesome twist on the technique for making fog in the 2010 era :P
ok dude now teach us how make fading out mesh (only thing i know its about blender alpha erase)
If only you can render it sepretly, and have a blur effect on it for more natural rays
give us the rbxl or a proper tutorial i WANNA USE THIS
can you uncopylock your game?
this is actually so cool
theres a simmilar way some people do it on blender
Woah!!!!! That is SICK!
Dude, that actually looks crazily good. This was definitely the more easier way than using bollboard GUI.
so kawaii
He came- He showed us how to make volumetric lighting- He left-
Awesome work dude. I'll try it out myself. I've been working on a retro anime cel-shaded / chromatic abberation effect, i should document a video on it some day.
If you implemented culling, would objects that’s models are offscreen but have volumetric shadows that should still be on screen also have their shadows disappear?
@aidencella4971 No, nothing would change with the shadows. What I meant by culling was removing excess beams that are off camera and making the beam box fit the camera's field of view
