@@rblxtutorials1881 agree, not everything needs to be a freemodel. Just do stuff yourself, the roblox engine is already easy to use compared to other game engines. That said, open source modules are still useful but you shouldn't just only use open source stuff.
@@chibisayori20 I mean, yes, it could be done by yourself, but not everyone has the time to learn about advanced lighting/rendering solutions when making a game - sometimes they want to focus on, y'know, their actual game, but still want to take advantage of a wellmade utility that vastly improves the art aspect of their game.

would be really cool if you could bake the lighting into a scene through a plugin so the framerate ingame would be more stable. this looks sick and I'd love to try making something similar but I don't know where to really start.
@@JourneyKid raytracing is the evolved form of raycasting. roblox's lighting engine using raycasts to tell if the light is colliding with an object and draws shadows based off the angle and some maths. raytracing is basically this - but shoot tons upon tons of these small rays, calculate their impact point, and bounce them again, till they reach the camera, where the data they carry (light info) is used to shade a pixel in the screen. raycasts on roblox are quite costly, meaning this would be a decent solution but still very expensive for roblox.
I do know of a few plugins that do this sort of GI but they aren't in real time, so this to me seems really impressive that this is interactive and running at a playable framerate. I'm not sure if this sort of thing is that scalable (for larger games), as increasing the number of voxels to fit a larger area would probably make the framerate tank.
Loved this, I've been looking into ways of doing this and never thought of probe based "real-time" GI. I'd love a deeper explanation on how you did the buffers, I've been working on my own for the past couple weeks now and only shoot out about 5 rays and calculate the color based on that.
I have a very high tech computer and it can run through realistic graphics, I would love to see builds in roblox with global Illumination and see how it would look like if it were real life.
Hi Daniel! I tried to implement this into studio on my own based off of your explanation, however, I’m struggling to create a buffer, smooth the lights and get more speed. Could you elaborate on how you fixed these issues or what types of algorithms you used? Thanks.

I wish that roblox would allow us to write our own shaders and give us access to cuda even if that creates a huge security vulnerability. It would give us access to so many cool effects that are either extremely difficult to replicate or just super inefficient to run through luau.
Wonderful work! I’ve always been bugged by roblox’s lack of GI thought about some sort of ray tracing method and at least a few bounces. As far as performance goes, could you break down scenes into chunks and only update areas that contain unanchored parts, or does parallel luau not work that way?
I think i know how he coded this. The local ambients are going to change colors where ever the player is at (or the camera). The colors are going to be like, lets say your inside and the floor is purple. The script is going to copy the color and make it darker to match where you are Edit: the one i said is something a bit more simpler. I dont know how he manage to make it everywhere
He says in the video He uses a bunch of point lights everywhere, which uses single bounce raytracing to get the color and brightness they should be It didn't actually take very long for me to make something that works, and looks about the same (Though admittedly mine is a good bit slower, and the recalculations are much more visible)
ok so, i have here a script which creates a raytracing effect on every part (you can modify if you want) local ref = 0.01500000013039 -- don't change local function analyse(v) if v:IsA("BasePart") and not v:IsA("Terrain") then v.Reflectance = ref end end local function descadded(desc) analyse(desc) end for i,v in pairs(game:GetDescendants()) do analyse(v) end game.DescendantAdded:Connect(descadded) observations: must use future lighting and maximum graphics. (btw, it's not real-time, and it's SLIGHTLY noticeable. you must be indoors for the effect to work, and it's only noticeable at spheres or at edges of parts.) and the effect is not always accurate, it may show inccorect reflections. basically a poor-made shaders LOL
i should use it in my game where the map as it is (barely complete) is already laggy enough with all the details, LETZGOOO will be game be the next cyberpunk 2077 >:D
Well you use actors by inserting them anywhere. Doesnt matter as long as the script runs. You insert any type of script inside, and that script will run inside a seperate thread, so the roblox game loop runs seperately from the raytracting for example.
Incredible! However, it seems as if you have a furry profile picture. Now, to be honest, We, I, and Us are not that very fond of furries, however, your experimentation with Realtime Ray Tracing/Global Illumination is very impressive, you have gained a vast amount of respect in various departments. Again, being honest with you, and everyone, (we) (I) (us) are going to look how to improve this and try to make it better. Best regards.

This is the most impressive Roblox demo I've ever seen!
It would be cool if it's open source!
A good way to make "fake" raytracing is by using invisible surface light blocks to mimic the light bouncing off where the light is
Clever

Bruh is this future lighting in an nutshell
we got Roblox rtx before fixed shadows
i really hope roblox takes a look at global illumination at some point, future lighting just doesn't do it :(
Very well explained, good job.
Little does this man know that the GTX 1660 is a raytracing card.
That GUI tho...blows blender, 3dsmax, c4d, maya and houdini ui out of the water! probably the ocean!
use future lighting for more accurate shadows.
How'd you make it so.. not laggy?
Please tell me!
The lighting is beautiful and i love it
please make this public
this is epic mate! keep it up!
Was that the gmod undo notification 💀
Wow incredible! Does it also work with terrain? And terrain water?
Probably not
@@Forcoyive seen you comment in differentvideos three times now xD.
hello again :P
thats actually crazy. does this work ingame too or does it use studio-only things right now?
Probably but it's so inefficient
For Anyone wondering, there is someone making this for completely free as a engine for developers.
where
This is like zeuxcg presenting his Future is Bright projects back in 2015-2016 (older players will get it; and I wasn't one of them lol)
it would be great to have a RT core acceleration for all this
garry's mods pop ups are crazy

he held control + alt while selecting
True but what about the pop-ups?@@taxevaiden
WOAHHHHHH!
This looks so cool! I want this in my game!
ok so, i have here a script which creates a raytracing effect on every part (you can modify if you want)
local ref = 0.01500000013039 -- don't change
local function analyse(v)
if v:IsA("BasePart") and not v:IsA("Terrain") then
v.Reflectance = ref

local function descadded(desc)
analyse(desc)

future is a bit differ
@@GeorgesWizard Yeah but looks kinda like it not exactly but kinda
@@AnomalyfyedSince I do have at least a year of experience on roblox studio, Future does have shadows but there really isn't any light reflection.

damn never seen something that impressive, what about the memory usage?
For my raytracer, Ram usage was not affected much. With 2k probes it only got like half a gig.

same bro
can you actually release this?
can someone make this open source so I can experiment, I don't know how to add this to Roblox
