Next Part: • Stylized Geometry Gras...
A fully functional grass shader that's made for the Universal Render Pipeline, it works without Unity's terrain system and comes with a bunch of features such as lighting, shadows, tesselation! This is the system I will be using in my open world game which I am developing on this channel as well, we will be coding everything ourselves so that you can understand from the base up how everything works.
PROJECT FILES (TEXTURES & MODELS) + COMPLETED PROJECT :

☁ In this video we begin our journey by creating the first of the three shader sections, the Vertex Shader. It's only setup, but it will set the foundation for the remaining episodes, this is a very complex system and will take a few episodes to get fully fleshed out!

Hey everyone thanks for watching the video, hope this helps you all! Fun fact, the first couple of seconds is a sneak peak of my Open World game that I have been working on for a while. In regards to my Open World Series, I am still continuing it and infact this grass shader is one of the things I have been working on, I haven't uploaded much due to school, but like I've mentioned, it isn't a project I will be giving up on :)

@Shamysoza92 3 года назад

Is it possible to add the shader only at a certain height?For example i have my mesh that has different color textures depending on height(grass, sand, water) and i only want the grass to appear on the grass part of the mesh, is it possible?

can you make grass interactive with player . i mean grass move side when player coming

@Indseta 3 года назад

Awesome shader! Is there any way to keep the grass direction up even when the plane is tilted?

@batchprogrammer108 3 года назад

Thank you :) Currently i extrude the points using the surface normal, but instead of that you can use the global up vector (0,1,0)

@Ryan-xq3kl 3 года назад

can you make a change to the script to make the grass curve or work on curved surfaces?

@batchprogrammer108 3 года назад

I think the grass should work on curved surfaces already.

@32kuba32 3 года назад

Is it possible that the grass is instantiated once and then stays the same? In our game we want to move platforms with gras on them but any kind of movement resets and reloads the grass. Is there any way so that doesnt happen?

@batchprogrammer108 3 года назад

Absolutely, the reason why it resets is because the rand function uses the seed that is based on the world position of the grass, so if you change that to object space then the grass will stay the same :)

@dongiovanni1993 4 года назад

Thank you for your efforts to share tour struggles. Note that there are dead links in the description (some vidz like CCC tut; IK series). And what about the school. I think, if you'd talk to the staff, they'll let you stay home considering you'll learn their 'ropes' on your own. Why will this work? They burn your time giving the knowledge with the most slow speed possible for everyone of the group to comprehend. And you're self-motivated, and you just don't need this. Just get from them themes that they will teach, and discuss some exams to verify your progress and that's it. And this stupid journeys will become just another line in your todo list. Working with old books is pretty easy. =) If they're too stubborn, there are ways to get some vacation (e g. foreign affairs=).

@batchprogrammer108 4 года назад

I'm happy to share this, also thanks for pointing out the dead links! Honestly, I thought about doing that a while ago but it's a bit too late I'm about to finish school in a month so I'm just going to get through it and get it over with, but I'm sure this advice would be great for anyone else on the same journey.

@dongiovanni1993 4 года назад

@@batchprogrammer108 Sure, a bit too late. :( Ma per chi arrivera.. Lucky you, at least you have had this thought. It's fun, but most people while being at school treat it as a real thing, a part of reality. They can never afford the thought that a school is actually just a game. Maybe it's wise to support this deceit to keep the Universe continuity intact. =) But in some rare cases someone just got to say something like "there is no spoon that bends, it's only yourself..." © =)

@@dongiovanni1993 Haha I love this! I hope more people see this comment :)

@rredenvous 3 года назад

Question, is't this performance heavy? I've seen ways to do it by using sprites systems where the grass is a textured plane only. Of course there are many planes but that way we could compensate with the terrain being very low poly...(I'm an extra virgin noob so i don't really know what i'm talking about)....

@batchprogrammer108 2 года назад

Well considering Geometry Shaders work primarily on computers I reckon you won't see much of a performance hit with some decent culling. However, I would recommend this more for situations where you can't use a terrain :)

@xxzippyzachxx 3 года назад

Is the vertex color based placement of the grass implemented in the complete project? Don't seem to see anything in the shader code for it. Just the initialization of the _VertexColorTesselation variable. Thanks!

@batchprogrammer108 3 года назад

Yeah so essentially in the Geometry pass of the Completed project you should see these lines at the very top: if (input[0].color.g < 0.1f || input[1].color.g < 0.1f || input[2].color.g < 0.1f) { return; } Now all it does is checks if the vertex colour is green, if not it doesn't draw grass there. You can use Unitys polybrush to vertex paint your meshes, just vertex paint a green colour where ever you want grass :) It's not very sophisticated at all, but I guess you could build upon this relatively easily.

@xxzippyzachxx 3 года назад

@@batchprogrammer108 Thanks for the detailed response. I used poly brush like you suggested to add the vertex color instead of Blender (wasn't working for some reason) and now its working great. Thanks!

@batchprogrammer108 3 года назад

@@xxzippyzachxx Awesome, that's great to hear! I'll try look into why Blender's vertex colors aren't working, but it may have something to do with the mesh import options but I'm not too sure.

Did anybody manage to get this to work on HDRP? I tried messing about with the code with no sucess :/

@batchprogrammer108 3 года назад

Hey, you might want to check out this link: github.com/keijiro/TestbedHDRP He has a bunch of HDRP Geometry shaders, however I think the only few adjustments you would need to make are to change the RenderPipeline tag within the shaders. Tags{ "RenderPipeline"="HDRenderPipeline" "RenderType" = "HDLitShader" } Something like this, instead of the existing tags; you will also have to change the package includes to include the HDRP files rather than the URP files. This specific shader might help: github.com/keijiro/TestbedHDRP/blob/master/Assets/CustomShader/Voxelizer/Shader/Voxelizer.shader Good luck, and if you get it working it would be great if you could upload a link to help everyone else out, thanks! :)
