Unity | I made an Interactive Grass Shader + Tool

[@MinionsArt]

So, this video is pretty old now, I just wanna add that Compute Shaders are better to use than Geometry Shaders, because they are supported on more platforms I've got the compute shader versions here : BIRP: www.patreon.com/posts/compute-shader-53587750 URP: www.patreon.com/posts/54164790 I'll make a new video for the compute version, there are some more improvements coming to it too :)

[@alexandressrocha]

the links in Pastebin do not work

[@youngjepark5835]

cant wait! I am not experienced enough follow the tutorials in the links above. I tried but ended up stuck.

[@youngjepark5835]

by the way, do you have any plans for uploading your shaders into unity asset store?

[@adharshgg]

Hey, I've pasted the 'GrassComputeScript', 'GrassPainter', and the 'ShaderInteractor' scripts in my assets folder, and the 'EditorGrassPainter' script inside Assets > Editor. And then, I added the GrassPainter on an empty gameobject. After I tried making a material from the shader, I get this error: 'tex2Dproj': no matching 2 parameter intrinsic function; Possible intrinsic functions are: tex2Dproj(sampler2D, float4|half4|min10float4|min16float4) Compiling Fragment program with UNITY_PASS_FORWARDBASE DIRECTIONAL SHADOWS_SCREEN LIGHTPROBE_SH _SHADOWS_SCREEN Platform defines: UNITY_NO_DXT5nm UNITY_ENABLE_REFLECTION_BUFFERS UNITY_NO_CUBEMAP_ARRAY UNITY_NO_SCREENSPACE_SHADOWS UNITY_PBS_USE_BRDF2 SHADER_API_DESKTOP UNITY_HARDWARE_TIER3 UNITY_COLORSPACE_GAMMA UNITY_LIGHTMAP_DLDR_ENCODING I'm working with BIRP here. Is there anything I'm doing wrong? How do I fix this? The shader looks super cool and perfect for my tiny project and would love to put this in there. Thanks in advance :)

[@ItachiX9]

In GrassComputeScript I get shaderinteractor missing error Edit : nm I was missing shader interactor file. Didn't saw it on ur patreon page at first

[@MinionsArt]

So at this point the shader is for the Built-in renderer, I haven't looked at it in URP yet, but it should be pretty easy to convert, I will update this post when I do :) Edit: It is done! Here is the URP version : www.patreon.com/posts/geometry-grass-47447321

[@repsejnworb]

Love you content mate, learnt so much from following what you make available for the general public!

[@gnomemann6986]

How do I actually get the shader into a unity project? Do I just copy and paste the shader code into a new shader? I tried to open one but it only opens up in shader graph.

[@anth378]

When I add your URP version, the shader throws the error "'GetAdditionalLight': no matching 3 parameter function", why's that? Please help i want to use so bad your shaders in my game, they look awesome

[@MinionsArt]

@@anth378 Just remove the 3rd parameter in that function, it's half(1,1,1,1) or something. (Means you're using an older version of URP than me)

[@anth378]

@@MinionsArt yeah, I'm using the one from 2019.4, I'll try that, thanks!

[@octobeanx]

This looks so similar to the grass in Genshin Impact, I love it, thank you so much for sharing!!! ❤️

[@benjaminreinsch392]

wow, I am absolutely speechless. You are a blessing, really. I only just started making my own games with unity and this is like black magic to me. Thank you so much for the hard work and taking all this time to explain how to use it.

[@rodmileski]

Gotta say, you channel and work deserves a lot more visibility than it currently has here in KZbin. Your game looks fantastic and your tutorials are very enlightening. All the best :)

[@Dertres]

crazy how this is not a default feature, very cool!

[@HUQAFU]

But there are default feature in Unity - Grass.. when you painting on terrain, you can draw plants, grass and etc and change its density and also its supports lods and changing of quality settings

[@mikeohc]

This is amazing, I still refer to your tutorial from time to time. I also want to thank you for providing the break down of the process!

[@agnarzb]

So unfortunate that I could not discovered your channel before. It is not just the tool but sharing it freely with the people is also amazing. I'll follow your videos from now on. cheers & take care

[@AntoCharles]

Wonderful job! Shaders hurt my brain awesome of you to share this with others :D

[@geri4367]

Thanks for sharing Joyce. The game is turning out great btw, can't wait to see more

[@MinionsArt]

Thanks! The game is going slow, but slow progress is still progress :P I'm planning on a dev vlog on Astro Kat soon.

[@babosarosa4304]

Wow, this is incredible. I've been searching this for a long time and you made it perfect. Thanks

Thank you for your Grass Shader! It's really helping a lot

[@IWasAlison]

OMG! Thank you. It's most beautiful grass I ever seen.

[@alexdamsa5423]

Wow! This really is a great and helpful tool. Unity should implement this in the engine, if you ask me. Or at least it should be a package. Thanks for sharing!

[@HUQAFU]

But it was already implemented in terrain - Check Unity Terrain Grass

[@bds_killerbaru9972]

@@HUQAFU the unity terrain grass is very basic and does not include this type of interactivity with grass

[@fredimachadonet]

Amazing work! Thank you Joyce!

Hi ! Nice work :o ! Is it really impossible to use it in HDRP?

you are a life saver

[@matteoburzi9016]

there is a method to incrase the brush size more than 10?

please can you share code for auto-generate

[@sanketpushkar6224]

having the same problem! can you please guide me if it was solved for you!!! please

What I did is I saved the mesh what I generated with the Grass Painter script, and used that mesh in my prefab. Also this is a pretty good shader, thanks for sharing

Thank you so much! Is it possible to make the grass not react to light? Unlit?

[@kibrjr]

How it can be compatable to HDRP? Thx for now

[@darrenbeckett]

This is awesome! But how can we make the grass Interact to multiple players or objects? We will need the shader to check for all GameObjects with the ShaderInteractor script attached.

[@jashwaaradhya2989]

Thank you very very very very very much :-)

[@artusartus4540]

Hello ! I am using urp with the compute version of your shader and it works fine on my mac but the grass doesn’t show up on an ios build. Do you know why ? Anyways great job 👍

[@iTobbz]

hi, everything appears to be working except the grass material is just pink, any idea how to fix this issue?

[@Chris-tv2kp]

When I try to do this and paint it just paints tiny orange dots and it is nothing like the video. It may have something to do with the material because the material icon is just a black circle while in the video it’s the icon of grass.

[@Block21312]

Hey! Do you think you could provide an update to this shader (July 2023)? I'm interested in using this shader for my project but currently cannot get it to work.

[@imdianapaola]

amazing, new sub here
