[@rubpty]

Thank you aarthificial for this great shader. The Shader works perfectly fine in Unity 2021, but for those of you trying to use the Shader in Unity 2022 you will find 2 errors. I will explain you how to fix them in a detail way. The first error is: "You can only call cameraColorTarget inside the scope of a ScriptableRenderPass. Otherwise the pipeline camera target texture might have not been created or might have already been disposed." This error happens in line 47 of the VelocityRenderFeature Class. To resolve it, you need to comment out the line of code in the VelocityRenderFeature Class (line 47 for me), override the SetupRenderPasses function, and then add the line in the new format as shown below: public override void AddRenderPasses(ScriptableRenderer renderer, ref RenderingData renderingData) { //_pass.ConfigureTarget(renderer.cameraColorTarget); //COMMENT THIS LINE OF CODE _pass.Setup(settings, simulation); renderer.EnqueuePass(_pass); } //ADD THIS OVERRIDE FUNCTION public override void SetupRenderPasses(ScriptableRenderer renderer, in RenderingData renderingData) { _pass.ConfigureTarget(renderer.cameraColorTargetHandle); //ADD THIS LINE OF CODE } The second error is: 'Hidden/PixelGraphics/Velocity/Blit': Couldn't open include file 'Packages/com.unity.render-pipelines.universal/Shaders/Utils/Fullscreen.hlsl' This error was mentioned in the comments below. This happens because Unity 2022 no longer has the fullscreen.hlsl shader in the given path. What I did was to open a project using Unity 2021, then I went to the given path: 'Packages/com.unity.render-pipelines.universal/Shaders/Utils/Fullscreen.hlsl', then I copy the Fullscreen.hlsl shader from the Package folder to the Asset folder and export it as a Package. In Unity 2022, you need to import the custom package, and in the Blit Shader, you have to replace //#include "Packages/com.unity.render-pipelines.universal/Shaders/Utils/Fullscreen.hlsl" With the new location where you place the fullscreen shader: #include "Packages/com.luvagames.fullscreenshader/Runtime/Shaders/Fullscreen.hlsl"

[@simoneparisi_]

[@omegaomega6838]

It seems that my problem wasn't actually the camera moving, but for some reason the shader that gives the velocity seems to be making everything yellow. I got you demo and tried it out. On your demo it doesn't seem to me that when I put the debug shader on that everything is yellow except the emitter. Is there any solution to this. I can't figure out the difference. What is causing my shader to be all yellow except for the emitter.

[@mathismeilby]

Thank you for sharing! It's greatly appreciated.

[@NishanGhoshgameshamelame]

Bro you made it! No words can define you - an out of bounds index. So this Velocity Emitter could be applied to multiple objects for multiple object interaction?

[@aarthificial]

Thanks! Yes, you can have multiple emitters

[@Dondela_a]

I don't completely understand, but the effect is very beautiful!

[@TheStigChristensen]

Thank you for sharing, much appreciated! I think there''s an issue with the pixelart_shader, I can not get it working smoothly with 8 ppi and no upscaling. If I try it in your demo scene, I get the same error, the bush get's distorted like crazy.

[@dmon9333]

did u manage to get it working?

[@omegaomega6838]

I've been trying figure out why the package just didn't seem to work for me and then I used the velocity debugger and realized that everything was messed up because the velocity doesn't really show correctly when the camera moves with the player. Is there anyway to make this work while the camera is moving with the player?

[@iondarii7621]

Thank you, very nice. I found that it doesn't sway if the camera is in perspective mode and follows the player, and works if static. When camera is orthographic all is good. Do you know why that happens? Thank you!

Hey, I tried to download this Shaders, but every time I put the Material in Sprite Renderer, it leaves the object purple and does not work, how can I solve this?

[@psyantologist]

Wonderful work =] I'm trying to follow along yet I'm confused by the demo project - it throws aplenty warnings about missing audio and all sprite PNGs are invalid files, 128 bytes in size, smaller than their meta information

Thanks! To quote the README file: "This repo uses Git Large File Storage to store image assets. If you want to clone the repo, make sure that you have lfs installed on your machine. Otherwise the sprites may be missing." You would need to clone the repo using git with lfs: git-lfs.github.com/

Just found out about this now

[@BlacksmithYT]

Hey I replied to one of the comments in here, but I do not know if it shows up for you or not. This is absolutely amazing, it works wonders, but I have one thing I can not fix: The bottom of my grass sprites are also swaying. I know that a _DisplacementMask is needed, but it is not showing up for me in the secondary texture editor. Why is that? Is there a way to fix it? Thank you in advance, and keep rocking the awesome videos! Update: nevermind, I am just very new to Unity, I did not know that I just had to write _DisplacementMask in the name field. I got it. Works like a charm.

[@forestgamez7824]

I've tried importing using git link, but it always fails, is there any other way to import it into my project?

[@TheWesleykid]

Hi! I tried to add it to my project, but it seems like it does not work with Cinemachine VCams. I added a velocity camera component to the Main Camera, which also has a cinemachine brain, it kinda works, but the buffer is behaving weirdly (sway for first few grass GO, but doesn't for others). I tried it with the cinemachine brain off and it works flawlessly. Nevertheless, this is a really awesome shader package!

[@alrightmarty]

I get no errors, but my sprite disappears when I add the pixelart variant of the grass or foliage shader. The normal version works fine though Edit: I went into the documentation, seeing if there was a special way that my sprites needed to be setup, and it looks like there kinda is, but it didn't change anything.

[@keratinor]

Hello I have a question. I don't know if it's me but it looks like your grass deosn't move at the base. But when I try this on a random foliage, all the sprite wave. Is there a way to keep the base steadi with your shader? Great job, i've been looking for this kind of video for a while!!!

[@aarthificial]

It's done using a displacement mask: github.com/aarthificial/pixelgraphics/blob/master/Documentation~/shaders.md#displacement-mask In this case it's a gradient - from black at the base to white at the top: github.com/aarthificial/pixelgraphics-demo/blob/master/Assets/Terrain/Sprites/plants_displacement.png

[@keratinor]

@@aarthificial Thank you !!!! That was a fast answer ^^

I love your channel man, consider me patronized(?) patronable(?)….that

[@omegaomega6838]

Is there anyway to make this work in a perspective projection. I've managed to make it all work, I just can seem to make the camera move with the player and show the velocity correctly because it's in a 3D space. if anyone has an answer to this feel free to share your thoughts. I don't even know where to begin to calculate the math for this.

[@joshuabidwell2614]

I would pay for this package if you could do a perspective version. Also, even with an ortho camera I can't get the renderer feature to work with 2021.2 URP. The camera works in ortho and persp but obviously has very strange movement in persp

[@Chief-wx1fj]

I would pay for a perspective version too. Please make this possible

:o A NEW VID WUT

[@shadowofcat]

i've installed the package in my unity project and it seems to work fine with a static camera but it stops working when the camera is moving it jitters and moves when the player is not near the object. i hope i can find a solution for this. anyways thanks for the cool package and i will playtest this for potential fixes.

[@glimpsygames2734]

the project doesn't work, only the package works and i don't know how to set up things, i tried to use the grass_shader and the movement is like the whole sprtite is moving around as you increase wind strength

[@glimpsygames2734]

I fixed, it by multiplying the velocity strength by UV.g or UV.y and sending the result, the same for wind strength, but i came to the second problem and that is while the emitter is moving or after it moved, the grass that's out of emitter radius moves too slow to the default wind strength (only the grass within the emiiter radius interacts well)

[@Chief-wx1fj]
