DEMO Godot Grass Particles Shader

[@AgriasOaks99]

Amazing! Ww need tutorial for this, please

[@wellwellwelp]

is it possible to learn this power?

[@sugimanjuara8195]

Could you share the reference ? Its pretty cool

[@pixezy8962]

What I mean by I've already shown it, is that I used it to decorate my scene in this tutorial: kzbin.info/www/bejne/o4ranpuQa8R7qq8 But I didn't show the shader neither what it is able to do.

@@pixezy8962 got it, thanks

Any reason for particles over MultiMesh instances? Just curious if there's some advantage performance wise?

[@pixezy8962]

Multimesh instance is less efficient for moving instances frame by frame since you have to use a cycle in gdscript to access each of them. With particles this is not the case, there is no loop and it's more efficient. docs.godotengine.org/en/stable/tutorials/performance/vertex_animation/animating_thousands_of_fish.html

@@pixezy8962thanks for replying. The grass vertices are affected by wind, but the grass transform doesn't change. So I'm still wondering why not use MultiMesh Instances for static grass? I feel like there is something I'm misunderstanding?

[@pixezy8962]

@@ijidau Yeah there is a misunderstanding because that's not how it works. There is no vertex transformation, what you see is the rotation of each transform of every instance of the particles and the rotation is amplified by the noise. The spatial shader just set the color of the grass.

[@pixezy8962]

Actually it's a personal preference to use particles instead of meshinstance, I like to use glsl rather than gdscript and the code is more compact since there are no loops.

[@ijidau]

@@pixezy8962 Thanks again for clarifying. I hadn't realised your particle grass was actually rotating, but it makes sense when I look closely now. I've made grass using MM and a shader with vertex manipulation to wave in the wind. It's the choice to use particle vs MM that I have been wondering about for the purposes of grass specifically. Seems like it's mostly a preference thing, rather than any significant pros/cons.

Very pretty!

It looks amazing, how you achieve that, and do you plan to open source the Demo

[@pixezy8962]

The code is very similar to, "the wall of particles" the difference is just that there is random rotation and displacement in every particle and the noise amplifies everything.

@@pixezy8962 Thank you, but if you can share the code you will save me a lot of time, if that's possible

[@dueddel]

@@_0xUr_ I second that. Not actually for using the code, but for studying. 👍

[@dmitrykolesnikovich]

Can I access this on your Patreon?

[@pixezy8962]

Yeah, it's there

[@felipefacundes1]

The video was great, you could make a tutorial! People really like the Godot video tutorial!
