Godot DEMO: Invisible transition
I think this is my first actual 2D shader. Yes, at the beginning in my channel I made a couple of effects using Canvas Item. I even uploaded the result to godotshaders:
godotshaders.com/shader/ripple-effect/
But this effect is on a 2D scenario with animated sprites. I think this effect can be useful to avoid being seen by an enemy or even for other things like removing collisions and being able to pass through walls for example. It would be best if the line animation is controlled from a Tween in gdscript.
This will be the first tutorial of the ‘Practical Shaders’ course on Patreon. I will create an interactive application where I will demonstrate all the basics of shaders to create the effects, as well as a library of functions. Both the interactive application and the function library will be public on Github. Because in my 2 years experience and statistic of my channel, nobody gives a d4mn about shader theory. 😆 But it's required so i can simplify the tutorials and avoid repeating myself.

Godot DEMO: Procedural Caustics

I have tried so many times to make a decent stylized water shader. Because I have seen so many games in Unity and Unreal Engine with beautiful shaders, but I just didn't know how they did something like that. It wasn't a simple texture, I know because it had animation. I think I just found it. As far as I understand you can apply this technique to any type of noise... So the possibilities are e...

About plugins. I have already shown the basic functionality of some of them in the form of shaders in this channel, for example water, grass and VAT. But I want to take them to a much more complex and detailed level. Besides making them more accessible to everyone. Godot versions 4.2,4.3,4.4 have amazing improvements that allow this. #godot #shaders #videogames

I miss to make just simple demos of cool effects. So I made this one :D *EDIT: It would be a good idea to make the corridor load infinitely unless the user takes an action. I saw something like that in Little Nightmares, and it's very easy to do, because the way the shader is built, the vertices are distorted according to the distance from the camera. So you can connect the pieces without any a...

Godot DEMO: Vertex Animation Textures and GPU Particles

I have a lot of ideas in mind to use GPU Particles and VAT. In the following tutorial I explain how the shader works and how to adjust the Blender/Unreal Engine plugin to work with Godot. Yes, there is already a port for godot 3.5 but it is way behind and doesn't work anymore. So we will use the most recent one in the latest version of Blender.

Godot: Bake and read position textures from a path
Переглядів 8722 місяці тому
This tutorial is inspired by Godot's native particle system, but also by VAT (vertex animation textures), so some concepts like reading positions in textures and interpolation between positions are related. The next tutorial is about VAT and I will try to "load" several animation textures randomly on thousands of models. So it is a good idea that you understand the principles of this tutorial. ...
Godot DEMO: Fish school (final)
Переглядів 4893 місяці тому
This is the final result, maybe it needs some post processing effects to simulate being inside the water. But that's another topic, and I think compositor effects are the way to go now. But it's certainly more complex. As far as I know, because it's a compute shader, it doesn't have the basic tools that specific shaders have, like the projection matrix or the view matrix. I don't think you can ...

This tutorial comes from Uniy from years ago. But I found it visually very attractive. It is very simple, maybe what is really interesting is to use the space of normal vectors to load textures, it is something I had not used before. It also helps me to better understand the concept of the hexagonal sphere to be able to do the effect I have in mind, which requires baked pivots. DOWNLOAD FILE (S...

I had already forgotten about this project, but I recovered it since someone commented that he needed to do something similar. I calculated the occlusion of the character with the wall in a strange way, it isn't raycasting because I do it in the GPU, but it isn't depth testing either because I don't compare fragment by fragment. But the concept of projection is quite interesting and I will use ...

Did you share this shader somewhere? it would fit perfect in a game Im making :D
Only on Patreon
Thank you so much for this. The official documentation is currently lacking the usual detail for compositor effects so this is super helpful and helped me fill in some of the gaps in my knowledge.
Back to the shader model 2 era? There were many ways of making true caustics, say myself I used photon mapping + a separable bilateral filter, and there were projects utilizing a deforming additive mesh as a scene to render into a lightmap. Both ways allow to achieve a correct lighting even from fluid simulations with a collider response, which really makes them stand out. Today you can even use the RTX features, although even the named methods create a nice effect for a very affordable performance cost.
it looks awesome! great work!
Is there a big hit on performance?
There's a hit on performance to be honest but isn't anything that a mid range graphics card can't afford
Maybe still showcase the patreon stuff that on youtube. I really love how SImonDev or - what's his name - does their videos. The videos on youtube are beautiful, and the viewer just gets that he knows what he's doing, and thus he is a respected 'teacher'. You should do the same, show stuff, make people eager to learn, tell them stuff why certain things are done in the way they are done - but don't actually show the detailed code, just snippets, so it looks easier, much more viewer friendly - and if somebody wants to actually learn what you are showing, they go to your patreon for a really good price they have access to the detailed materials. At least that is how I would do stuff. Most of the time, people just want to see cool stuff, and that is a market gap in my opinion, that you could fill.
Still dont understand y your channel not popular. Your videos are really useful simple and looks cool.
Very nice

That's great work! It doesn't require transparency? I'm looking for a solution to make object between the camera and the player invisible. The file is missing in your link. Do you think you can provide a github or new link, please? Thanks!
Uploaded again. I have a tutorial to make objects transparent between the camera and the player.
You're doing awesome work, that makes me wonder if you know a solution to my problem : In godot 2D, (4.3) I build some gpu particles, and I would like them to interact with each other when they cross each other, so I turned blen_mode to 'blend_add' and then, when the background is pretty colorfull, it's a whole white mess. I would like my particles to add togethers, but not with the environnement... I tryed a bit of things whil adding a custom shader, but I don't see how I could make them add there particles colors together and then mix them to the world. Do you know a way ? It would help me tremendously !!!
@@melpeslier It's an edge case. Don't know if it's possible rendering and mixing particles inside a transparent viewport, then mix the result with the background using a shader.
@@pixezy8962 Yup indeed, thanks !
@@pixezy8962 Hi again ! Do you know how to emit particles in 2d from a texture depending on alpha value from a subviewport ?
@@melpeslier I don't know if you mean using a custom shader to emit particles from a mask. Maybe something like what I do here but in 3D: ua-cam.com/video/cgVmANy6JBg/v-deo.html In another tutorial I put the source code. But I don't have anything in 2D, you would have to adapt it yourself. Also assuming what I believe is correct, you would have to copy from the original godot shader all the particle velocity code. Not an easy task
why not change the compression setting to an interpolated one and do only 1 texture read? that will save tons of performance. see Donald Martin's vertex animation in godot tutorial.
It was my first try, because this comes mainly from UE examples and they use bicubic, I think is the same that bilinear. But I couldn't find it. If i remember correctly choosing filter type was different in 3.5. I gave up, maybe too early... If you know where is that option located please tell me. AFAIK this is the only way to setup the filter type in Godot 4: uniform sampler2D absolute_map: filter_linear;
How did u make this ? I know the sdf but the wall effect is.... How to make it pixel cut like that ?
"Quantizating" the world space, I used to call it "the grid" effect before, but I see that Unity guys use that term for everything that looks like squares or blocks like in this example. This is the 2D version: ua-cam.com/video/wAwQW1TxJq8/v-deo.html Here is the solution, basically I quantizated (maybe I am using the term in the wrong way.) the SDF over the world space: ua-cam.com/video/GDbSqZpy1TY/v-deo.html
Tutorial??
nice work!!!
If you had a shader course, I would buy it
Great!!
Where do learn all these sir?
So good! Also nice that I recognozed a whole lot of the shaders from earlier videos that I have obviously watched. Overall a really great outcome. Keep up! 😘👍
incredible work boss
Insane
Great showcase, lot of nice effects!
crazy good
So cool man. Great work 🤩
Too good and cool
Very cool!
Several reasons for my upvote * using the Imphenzia color palette 😅👍 * using Godot in general 🤖❤ * making such a cool shader 😎 Looks great! Keep up. 😘👍
❤
This is so cool! Please continue the tutorial on this! Bless you!
i'm too tired to process what i am seeing, i thought it was abstract. there's no comments so i thought i'd add one :) Y, M, C, A! Y, M, C, AH-HEY! :) (sorry it's not helpful i use c++ for modeling)
wow, thats is absolutely UNREALL
My god, this is perfect! Thank you so much! It's EXACTLY what I needed
For performance test you should compile project and run it from exe, godot have several optimizations.
I think your original voice is better than AI voiceover. Anyway good videos!
Well done. Waiting for the next vid!
it will be a lot faster than skeletal animation But why did you just code interpolation code and reduce key frames between vertex. this way you can get smoother animation for example my monitor 240 hz it is not suitable for me
liked and subscribed. the community needs more vertex animation texture tutorials!
Can you please make a small tut on how to add foam at the edge? My shader would like that very much
lol exactly what i wanted to make, thank you. I was thinking to fake it and make something simple, just a mesh with hexagons painted on it and half transparent 🤣
finally, someone explains vertex animation textures on godot. thank you.
Ah that's cool, I haven't seen vertex data used in that way. Always found vertex animation interesting
Geonodes in blender can be used for creating the same textures. And many similar things.
This is so unbelievably smart and the result looks so unbelievably stunning! Really great work! 😘👍
This guy is sole savor of godot 4 technics
way to just skip the most important part in world space :D
For Godot 4.2+: vec3 world_position = NODE_POSITION_WORLD;
@@radivarig that's node position. it gets the position of the node, not the pixel.
Really cool👍
This is great! 🐟🐠🐡🪸🐚
Any performance gains over MultiMesh?
Not really in this case. MultiMesh and particles are both handled by the GPU. The only difference might be a little lag at the beginning in the case of MultiMesh as it requires a cycle in GDScript to position the instances.
cool
