I Made Sebastian Lague's Procedural Planet In Godot 4 

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

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

Thanks! ❤

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.

@@athillion (not sure what's going on with RU-vid, I attempted to answer 3 times already but each time the comment goes away in limbo Oo)

6th attempt....... my voxel engine and the demo project are both available on my Github. Sorry no links in this comment, I feel like RU-vid 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 RU-vid 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 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?

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... 🤔)

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.

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.

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.

Sure, go ahead!

Thanks! I used beta 3, then 4, then 5 🙂
