GRASS SWAY in Unity - SHADER GRAPH

[@Brackeys]

Hey everyone! To those of you who can't find the package: Unity has moved the "Show Preview Packages". You can now find it under Edit -> Project Settings -> Package Manager -> Enable Preview Packages. If you check that box, you should see preview packages in the Package Manager! :-) Stay awesome!

Can you make a tutorial on how to make interactive grass (grass parts when you walk through it)?

[@rfxstudios9481]

Hi brackeys, when I try to download the grass assets it brings me to a website where I download the assets (in a zip file), how do I then import them into unity? Much thanks👍.

[@rpamungkas13]

Hi, The grass assets link cannot be downloaded. :( Could you post a new link? thank you. :D

[@wanderingworld762]

For those of you working in LWRP or URP, if you get shadows appearing like block, you need to use opaque mode and set alpha clip threshold to something around 0.8.

Hey guys! You don't need to subtract anymore in this part 12:34! You can connect the node "Combine" with "Transform" directly!

[@rhapen]

it was disappearing without removing the subtract with camera thank you

[@TobiDerKrasse]

thank you very much, my grass disappeared before, now it shows up correctly

[@scdijkens]

This is true but since HDRP still uses camera relative rendering it produces another artifact that causes the wind noise applied to the grass to be camera relative. This artefact makes the wind effect to be faster or slower depending on how you move the camera. The work-around for this second artefact is to change the first position node that leads into the tiling and offset from Space: world into Space: absolute world.

[@richardl116]

[@harrygeorge3665]

what do you do with the gradient that stop the bottom of the grass from moving then ?

[@frost-hex]

I search for a very long time for a method that doesn't need terrain to plant moving grass, and your method works the best for me, and I don't know how to express my appreciate to you! This is truely a magnificent tutorial with detailed mechanism explanation. Thank you so much!!!!!

[@kubalas688]

For the people who have problem with invisible grass: Now You must substract camera position not on the end, but on the begining, directly after first position node, before tilling and offset node. That works for me - I'm using latest available version of LWRP and Shader Graph (6.9.2.) and I don't know that fix will work in other versions.

[@ragest_blender]

it works, thank you!

[@oconop2310]

4 years later and it this fix still works! THANK YOU FOR SHARING

[@XxRokuChangxX]

I love the fact that you can see the animation is made by moving layer in PS at 5:50

[@Woodythehobo]

For those in Unity 2020.1 URP with a PBR master node in Shader Graph and if your grass has black areas on the mesh, then you may want to bake lighting: Window > Rendering > Lighting window > Scene tab > Click New Lighting Settings > Hook up Lighting Settings file to the Lighting Settings selector > Keep everything default for now > Uncheck Auto Generate and click Generate Lighting. May take a few minutes but it fixed the issue for me. A second way of "fixing" is in Shader Graph plug in the grass Albedo/Diffuse colour node into Emission too, the only issue with adding Emission is that shadows will be less effective on the grass, because it's essentially emitting its own light. You can visibly see the shadows move on the mesh if you select your Directional Light in the scene and rotate it.

Hey guys, For those who are having the ! next to their node: 1) Download the last Render Pipeline from the Package Manager (HDRP and the other); 2) In asset folder and Create -> Rendering -> HDRP asset-> name it anything. 3) Goto Edit -> Project Settings -> Graphics then Drag and drop the HDRP asset (pt.2) onto the Scriptable Render Pipeline Settings. Have a nice day!

[@cinnamondum]

brackeys, you made this video 3 years ago but is it still one the best source of information

[@ProxyDoug]

Don't you love when Unity changes how their tools look more than how they function so much it takes you double the time to follow a tutorial... Edit: With that done, here's a tip. Instead of using a gradient texture for the color, you can add two color parameters and put them on a Lerp node, then use the same step done here 14:47 to get a nice gradient in the grass object. It's specially useful if you're going for a more fantasy look and need weird looking colors like blue or red grass.

[@xXnickylodeonXx]

Wow, one of the best tutorials I've ever seen. Very easy to not only follow, but actually understand the process. Thank you so much!

[@DerSnubili]

Just wanted to add that as far as i can see in the newest version of unity HDRP you don´t need to subtract the camera position, just go from the transform to the position input (like in 12.12 in the video), if you do it the way shown afterwards in the video you will get some strange object placements/movements, cheers !

[@oivinf]

I love this and it is really helpful, but a quick note on using the "metallic" property as a map here: Only metallic objects display any sort of metallic reflection, and for organics (such as grass) it definitely should be turned off all the way ie. be black, unless you're trying to achieve a specific stylized effect. It looks like in this case it might be, but then plugging in the map is redundant in the first place, so that saves you a couple clicks every time you set this up! IIRC the metallic property is - in realistic terms - actually more of a binary effect that a material either has or doesn't have. (But of course, with something like dirty metal you would have varying degrees of metallic properties displayed across a map.)

The problem with this method is it's highly inefficient and the moment you scale this into a proper, full game, it's going to eat too much resources. Acerola has some excellent tutorials on grass, and other things, and discusses optimisation and the need for it, and also has a video on why most tutorials on youtube (like this one) is an extremely bad way to go about implementing grass.

I can see now why you're popular. You give out assets that are super useful. Because of your asset, now I know how to model a grass mesh out of intersecting planes from blender to unity. Those axes aligning are super tricky! Unfortunate you're a unity youtuber, I was constantly curious how you modeled that mesh before figuring it out that it was the axes from blender that was throwing my grass around.

[@brandonlaventure8086]

Hi guys, If you have a problem with materials appearing pink, this is how to fix it: After setting HDRP as render in project setting, you have to set linear workflow. For this go to Edit > Project Settings, then select the Player category, navigate to the Other Settings, open the Rendering section, and change the Color Space to Linear. Then it should work :)

[@SrZarolho]

Thanks Brandon! It solved half of my problem, but i still got pink material. :c I solved it by re-importing the hdpr package and changing Standard shader to HDPR/Lit for the models that didn't need a custom shader.

Hi Brackeys, Nice tutorials sir. I have a question: does it really effect on performance? if so, how big can we make to not to overload our pc

[@xd-fu6ry]

This method is actully deeply terrible performance wise because it is calculating the perlin noise every frame and not pre computing it. It also uses geometry shaders which are in general pretty low performance. So with any real large amount of grass things are going to start chugging.
