Smear Effect using Skin Mesh - Godot 4.4
A lot of nice effects can be done with the new feature in Godot 4.4. that allows you to copy the state of the mesh animation from the GPU. This project was a custom job I did, based on an example in Unreal Engine.
Unreal Engine is several steps ahead of Godot in this regard. Complex 3D effects on the GPU are UE's specialty, and it has very powerful tools to achieve them. But it is now possible to recreate some of them in Godot in a rudimentary way. And I think if I use a compute shader next time this is will be a lot faster.
I know, I know, calculate 5k vertices on the CPU is quite slow.

This is just an update of this tutorial for 3.5 ruclips.net/video/RXIRkou021U/видео.html It was a pain trying to upgrade from 3.5 to 4.3, so I just rewrote it and made some modifications to make it work as a tool in the editor. Then I rewrote it again in 4.4 so it has nice shaders and that pixel art that looks amazing. It requires 4.4 just because of 2 useless buttons that run in the editor, so...

* There are just 5 SDF nodes. I was counting the root node by mistake 😅 This is a small plugin but it has features that are tricky to combine: SDF shapes, simplex noise, fresnel, unshaded inner faces (using a next pass shader) It is still missing some features that I am going to add gradually.

New version of the "Invisible" project, now it works with any spritesheet ( I hope). Little but useful udpates to ShaderPedia, It's still a prototype so it requires a lot of work. But I think it can be useful to you right now (with just 4 examples 😆) Yeah, I'm working on the tutorial too, but I needed my application to be at least somewhat functional. I came up with an idea to solve the problem...

I'm back This application will serve as support in my shaders course (Patreon). But this is free on Github. It's missing a few things like a description for each of the shaders for example, and of course like 50 examples that I'm thinking of It can display not only 2D but also 3D shaders. For that I have to use viewports and solve some details. SHADERPEDIA github.com/pixezy/ShaderPedia SHADERLI...

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...

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...

Keep it up! :) Loving your stuff!
Very nice! I've been waiting for someone to do this effect in Godot. Makes me even more excited for 4.4!
Damn cool 🔥
Awesome work!
Super cool!
Awesome!
Fascinating stuff, all noted and put to one side for 'later' 😁👍
Wow.. going be tricky switching to normal to effects.
If in 2d, change ALBEDO -> COLOR and shader_type canvas, you'll get the same thing for this example.
Is there any way to use 1 uv for base colour and 2 uv to display some crack, sticker and stuff... I need help.
UV coordinates do not work that way. They are not like "layers". But there are maps or channels. In general, all color information is stored in the diffuse map (ALBEDO). To combine colors in real time you use masks (BW maps) and the mix function, you can also overlay textures using "decal" nodes.
Thank you for sharing this shader, it's really useful. Would it be possible for you to create a similar shader using visual shader?
Should be possible If I remember I "translated" this one from unity shader graph
This is awesome!
Very cool!
is the source code available anywhere?
I think I just lost the project. I'm going to make a tutorial maybe
@@pixezy8962 I would love that!
That's a really cool combo of shader + spring
this is very cool!!
Well done!
Just wanted to say that your channel is probably the best one when it comes to more advanced Godot concepts. I'm gladly supporting on Patreon you and I hope even more people do! ♥
Can you make a tutorial for this cape ?
cool stuff!
this is so poorly optimized, how are you going to have an entire field when a single square of grass takes 19 ms to compute a frame?
Just how Noita's player scarf and Rainworld slugcat's tails probably work, cool
What about bg3-select-object-outline effect? Or from divinity original sin 1
This is one of the coolest effects I've seen someone doing in Godot. I'm new to non-visual shader programming. Is it possible to have each piece rotate continuously individually?
I guess so, they could rotate with respect to the TIME variable, and to make them rotate differently, use the random function
@@pixezy8962 Yeah, I've been experimenting with that but I'm not sure how to get the 'rotation' property of each of the pieces
Wow I was literally looking for this yesterday! Thank you! Do you think after the version 4.3 in Godot is possible to do Stencil Buffer illusions? I haven't found any content about it...
I also have been waiting for this for a long time. Who knows, maybe it will be implemented in 4.5. Compositor Effects and copying from Skin Mesh Data take me off guard. I was looking for ways to implement it myself in C++, thinking it might take years to be included in Godot, and bang it's done
This could be improving by scaling copy interval by the referenceVelocity divided by actualVelocity, making the ghosts generally equidistant. (need to catch the case where velocity is 0, probably a TTL value that consumes the ghosts one by one is needed, too - small changes, big impact)
Damn ! That's awesome ! Can't wait for it to work with gpu particles !
Thanks for the tutorial, i really love it, ghost trails is really cool !
WOW amazing ! Is it just visual ? I mean does it cut off collisions too ?
@@melpeslier Just visual effect
@pixezy8962 That's super cool, I wonder how you made this, to pass the sdf datas to the shader, do you transform it to a texture ? or are you using compute shaders ?
Yeah I was doing this by instancing the mesh and applying the dissolve shader with an overtime effect script and then freeing it. It was cumbersome because needed to get the animation player and its time to set the model in the correct position on enable.
Awessssomeeeee
Nice work, Pixezy! If possible, can you change the project setting to compatibility mode? I can't open the "forward+" projects on my device.
dam man godot can have unreal chaos system hahahahhaha
hello
Where did you make this shader available?
this is one hell of a good plugin
Sure, now lets see the FPS 😑 EDIT: Nevermind saw them in the video, DAMN THATS BAD. It isn't like you are covering a large field or have crazy animation, thats just terrible...
Thanks a lot
Shaderpedia looks nice, thanks for you hard work!
Cool, but can you generate a collision for this?
It is a trick, because the geometry is deformed with respect to the camera. At zero point (the player's position), there is no deformation. Then you can use a standard collision and it will work.
I often see the method where neighboring pixels of a height map are sampled and compared. What's the advantage of the method you present compared to other ways? I did a tiny test, seems to be a bit faster to only sample ones as you do.
This method does not use samples, since it uses dfdx dfdy which are the derivatives automatically generated by the GPU. It is way more efficient, although it is somewhat less accurate than using samples, but in my opinion the quality is very good and there is not much difference to using sampling.
I will keep this function in my library, I mean that you only need to sample the height map once. I have also had a long time issue trying to get the orientation of normals right. Multiplying my mathematical functions with VIEW_MATRIX solved that.
thanks for it, this save me lot of time in my project
couldnt understand a word of the intro because of the loud music.
thanks for it playlist is saved me lot of time
you can have the ray record what it collides with into an array, and have it loop ignoring the objects in the array, until it doesn't collide anymore, than return the array. that will get all the collisions if you need it.
How ? We want this, we need this, we love this !
Thank you for this channel, I learned a lot from your videos! I was able to replicate these fills and masks from the tutorial, I'm trying to create a dynamic plane cut for when the player enters a house/building it auto hides the upper floors/roofs my problem is that all of my assets have overlapping meshes so it always shows pieces of the overlapping walls inside the mask... Do you know if there is a way to make the mask only follow the contour of the cutted elements?
I have tried to solve this problem several times, but I have not found a solution. It seems trivial, but it is hard to solve. Maybe a workaround would be to generate an SDF (assuming the SDF is generated correctly with overlapping faces) and hide any geometry inside it Maybe even the SDF would not be generated correctly. This is why I use meshes that are perfectly sealed and have no overlapping faces at all.
Thank you for the tutorial! I was trying to adapt it to my isometric game, making it cut the upper floors/roofs so I can see inside a house when the player enters it, but as the shader "discard" the upper portion it removes the shadows as well and I wanted to keep it. If i change the GeometryInstance3D.transparency it keeps the shadows, so i tried changing the shader prop "discard" to "ALPHA = 1", it made the cutted part fully transparent, but removed the shadows... do you know if there is a way to keep the shadows from the cutted part?
I answered something similar before, here in the comments. Maybe the question and answer are useful to you.
Hey this is the most clearly random&noise tutorial for Godot user I ever watched! Thankyou!
Thank you so much. I learned a lot from this. Not everything makes 100% sense yet, but I was able to reproduce the table effect. Now I'll attempt to tweak this for my specific needs.
