Glad they finally added compute shaders. I remember having a long conversation about that on the Godot Github a couple years back but it was decided not feasible due to the OpenGL 2.0 support and we would have to wait for the Vulkan renderer
Can you make an issue for this with your current struggles and project as an example of why mult-pass post processing is needed. The Godot Core Contributors are fantastic but tend not to add a feature unless there is a documented use case for it. This seems like a perfect candidate
this is beautiful. i really feel like i want to understand this . i love nature i think about it all the time and i think understanding this will make me enjoy thinking about it even more . thanks .
I'd just like to say you did an excellent job both on the project and in making the video. It's very well articulated from start to finish. Very thorough!
I'm been trying to hack together deferred rending in Godot, and the multi-pass requirements for it are very simmilar to your project. I'm dissapointed that Godot still isn't up to the task, and thank you for trying it first. You've saved me a lot of time
My experience with viewports in 3.x was "don't use them ever" as they're quite fiddly to setup and then also extremely slow. I see that hasn't changed much. In my case, I was creating a ray-sphere intersection atmosphere similar to yours, however I didn't care that it wasn't true volumetric; I just wanted the sky to look good in a first person shooter project I was working on. So what I did was adapt the original viewport version to fit on a hemisphere and then to draw the hemisphere first (render order used to be set by tree location; now that's further adjustable in 4.0 on top of the usual node order) and force each fragment to be max. depth. This worked great and brought my performance up immensely; but obviously it's not without issues and isn't a fullscreen effect at that point. Happy to see it's not just me, at least...
In my project, I use a full-screen quad for planet atmospheres and lens flares. The atmosphere is a simple ray-sphere integration, but maybe it could include scattering to be more fancy (curious about baking optical depth! I might poke at your code some day). I don't use any viewport. When I get far enough from a planet, I switch the fullscreen quad to a cube around the planet, which is done seamlessly. It allows to layer multiple planets on screen, while reducing the amount of pixels to process in fragment shaders, resulting is better performance. I haven't tackled oceans though, which might be tricky. For oceans I was thinking of actual geometry (a sphere that tessellates when getting close) which would use depth too, so it would not be bothered by the other post-processing effects and would be able to wave, although I'm not sure about the effects of overdraw and transparency. In the distance it could eventually collapse into the ground shader to prevent Z-fighting, since my project takes place with large distances. It would be great if Godot allowed more interop between compute shaders and the main renderer. And also provide more APIs to do postprocessing effects as well, though I'm a bit concerned that my trick switching to cubes would not apply there... Check th-cam.com/video/Cq_dHmgcc7U/w-d-xo.html
This is probably a better approach than multiple viewports, I was also considering using actual geometry for the ocean, since I wanted to add actual waves to it. I stuck with the full-screen quad for now because I wanted the project to reflect Sebastian Lague's as much as possible so I could make a more valid comparison. If Godot could get better support for custom post processing, that would be amazing! Your solar system demo looks amazing. I suppose your voxel engine is not available on GitHub? I am looking into implementing something similar using Dual Contouring.
6th attempt....... my voxel engine and the demo project are both available on my Github. Sorry no links in this comment, I feel like TH-cam has an auto-mod which deletes comments way too aggressively or something
@@ZylannMP3 Yeah, for some reason often comments with links are aggressively deleted. Even links to other TH-cam videos. But it's an interesting approach. How does ist compare performance wise?
@@Sk4lli I haven't tried the demo from this video yet so I don't know about comparison, but my project can run at 60fps on my 1060. I should probably try uncapping framerate to see how high it goes, but I not only have atmosphere in my project, also got lens flares and a multiple voxel-based planets with scattered rock props^^ I actually have an ocean on one of them, but it's just a big sphere. And later I want to add more fancy water, impostor foliage and planetary rings. And player-made structures such as buildings and ships, but that's way later in the future xD
I've worked with some CUDA in the past, and there's a LOT of similar concepts between CUDA kernels and compute shaders. Im really excited, there's a ton of cool things you can do with that kind of power that you can't do with fragment/vertex shaders. You showed that off really well! Man, it sucks that they haven't added multipass shaders. I really wanted those.
I was planning on doing this eventually, but it looks like you've beat me to it.

Man nice video, you accomplished what I am trying to do for my game. Do you mind if i look to your code and probably use some? Also i wonder. What game are you developing?
Sure! The code is free to use 🙂 I am working on something similar to a colony / life sim, maybe a hybrid between Spore and No Man's Sky, but smaller scale.
I'll have to take a closer look at your project but I'm pretty sure you can create the ocean and atmosphere effects without resorting to postprocessing the way you are doing this, instead rendering a sphere around the planet and embedding the logic there should result in the same effect. Also you can likely combine your ocean and atmosphere pass into one. Both work on the same dataset, if the height you're sampling is below ocean depth you perform the ocean logic to get your base color, else just take the color as is. then apply atmosphere on top.
I feel like you are correct, but bunching several post processes into one isn't a correct solution, rather a workaround for Godot, IMO. If it's a valid technique (IMO, it is) and can be done straight-forwardly without an engine (IMO, it can), it's an issue that Godot cannot do it, no?
Interesting video and very good exposition of the process and problems! I don't use Godot (I decided it'd be more useful to learn Rust while trying to write games, so I started with Bevy) but I'd really like to see more videos like this!
Hmmm, with Beta 6 I'm getting a `SHADER ERROR: Tokenizer: Unknown character #35: '#'` on the line `#include "res://materials/shaders/include/Math.gdshaderinc"` of a shader that should be the Ocean one (has a uniform float OceanRadius - and no, there's no shader resource name anywhere I can see... 🤔)
I thoroughly enjoyed this video Athillion! Thank you, Thank you, and Thank You!!! I watched Sebastian Lague's series on the delivery game he created and was excited to see him using "real world" data to create a virtual version of Earth to fly around. My question is... could this be done in Godot, to the point where player characters could be placed in specific locations to explore and travel through? These characters would be land based at first and have no ability to fly around until later versions of the game. I have a concept for several games that I could implement, and one of those games would be based around a futuristic version of Earth gone terribly wrong, as well as other planet exploration due to having to leave Earth because of what happened.
Bravo! I have been meaning to do this for his slime sim, but have been looking for a way to use OpenCL since I know a bit of that. I might just end up using godots python binding so I can use pyopencl to set up my buffers and launch my opencl kernels... I like OpenCL because its practically just plain C without too much extra syntax.
Just asking, How portable is OpenCL between systems? Is it possible to ship a game that includes OpenCL code for Linux, Windows and Mac easily? How does the OpenCL dependencies get installed? Asking for general information not necessarily that it is the best way to go for making with it games. Thanks.
@@astroid-ws4py In theory, the code you write should work with every vendor that has implemented the OpenCL specification, but a bunch of stuff is implemented as extensions I think. For instance, I mostly use it on my AMD card and when I went to run my code on my laptop with intel hd graphics, it turns out that it only has floats and no double types (if you don't necessarily need the precision, you can just swap with a typedef). Though I think that's just an integrated graphics thing, most modern GPUs should have doubles. The OpenCL deps usually need an extra driver like CUDA for NVIDIA or ROCm for AMD (separate from the graphics driver), which the user needs to install. I've only really tried on Linux and only really on manjaro and arch, where there is a opencl-amd AUR package, which is a one click install. It really depends on how easy it is to get users to do so. After that, if you're working in C/C++, as long as the driver is installed and your program can find the so/dll, none of the code should be platform specific, so it should all work. This shouldn't be too different for a wrapper in another language like pyopencl, but it needs to also know where the .icd file for the driver is, so this might add some extra steps. Also, the user might need to also install python in that case, unless it can be bundled with your project (I imagine Godot does this, but I haven't looked). TLDR: Code itself should be almost 100% portable, cpu-side only the OpenCL header location import changes and only for Mac (and once its compiled this won't matter for the user...) and gpu-side, well it should be fine if you're writing pretty plain code with no fancy extensions. Dependency-wise, one driver is needed.
I'm sitll fairly new to gamedev, and I don't know much about shaders and post-processing, but I do know that Godot 4 is still in its infancy, as are many of its features. Godot doesn't have a very large team working on it, and they can only focus on so many things at once... so, especially when it comes to advanced visual effects and optimisation, it's going to be playing catch-up to Unity and Unreal for some time. Its real strengths lie in its workflow and its open source nature.
that's cool! i tried to do this about a year and a half ago, I got the planets generating mostly OK but didn't get into the shaders. I also never got to implement an LOD to allow for surface exploration, not to mention colliders.
Instead of trying to write to the screen texture you could use a copy of it make the changes then use quad mesh and scale it up to the camera View matrix then apply that texture to it. Ive never actually attempted it but ive seen multiple screen space shaders do it. cell shading for example or you could even use a texturerect Control node set to full screen. For the MeshInstance version just add this to the shader. To line it up with the camera void vertex(){ POSITION = vec4(VERTEX*scale_multiplier,1.0); }
This seems quite similar to how I am doing it already. I take the viewport texture from the source camera and provide it to the next step, which is connected to another viewport, which produces a new viewport texture. 🙂 The shaded texture is slapped on each corresponding billboard quad mesh.
the compute shaders don't use the shader language of godot ? since i remembered godot having a gdscript-like shading language that gets compiled to glsl rather than directly writing the raw glsl
Good video! I think the stars look too bright, in real life they are actually very dim but your eyes adjust to the dark to make them brighter. The absence of this in the game makes the transition from day to night look a bit unrealistic.
I'm not sure if I completely understand why you had to use multiple cameras, as I'm not too familiar with godot, but do you need to run those shaders as post-processing effects like you did in unity? Couldn't you just put a slightly oversized sphere around the planet, and run water and atmosphere as a frag shader on that? Or, to also have it work when inside, just put like a small quad right in front of the camera, and run the shaders as frag shaders on that?
Godot's current postprocessing setup is really basic, and the developers are aware of this - there's already an open Github feature request, and something much more flexible and more performant is expected to be added somewhere down the line... but not any time soon unfortunately. Hopfully sometime in Godot 4.x.
Godot 4 has sky shaders. Maybe you could convert your stars to it. Is it necessary to have fxaa as a viewport or csn you get away with just enabling fxaa in ProjectSettings.
Hiii, I donn't know if somebody have tried enable antialiasing and noted that effect dissapear. Somebody has idea what part of the effect can be affected by this? I would appreciate all possible help :)
I'm getting to the point where I'm comfortable with my knowledge in web development, but most of the stuff you've shown flies totally over my head. I wonder if I'll ever get to a point were I can understand this.
it's been already a year for me learning godot and am still stupid as f* . i can make character controllers and inventory and levels and stuff but goddamnit i still feel like i haven't learned anything

how can i do that in shader
or gdscript
thing i dont like about it is that i cant have some variable for objects that i can read while post processing
Great work!! I always wanted a Sebastian Lague-like video on Godot, you nailed it!!

i cant even work on shaders from sabestian league.
