Oh! now I understand, finallly. Thank you very much! May God bless you and your family!

19:15 "material" doesn't work now (3.1.1). Have to write "self.material"

Thank you so much. This video was a HUGE help! It sort of just made some things click for me that I wasn't understanding about shaders.

keithwinget

A bit of (I hope) constructive criticism. The tutorial is about shaders, but you spend most of the time building a (very simple) interface to just use the shader.

This is what I'm looking for! Thanks

astwyr

Thank you for another great video and initiative !

this is... haard...
i think some more introductory stuff like dealing with color and alpha would be more easy to grasp

Do you not get long term instability from doing adds like this

michaelmoran

I engineered a boat with cosine waves.

I really wonder if and when Godot will have shader nodes (like Blender nodes or Godot visual scripting) for those of us who don't want to code in GLSL. I could have sworn I saw a shader node editor long ago, but for the older version of Godot.

When trying to save the shader, it fails and shows a warning: "This resource can't be saved because it does not belong to the edited scene. Make it unique first."

Arklte

Is it possible to somehow give the shader a dynamic set of values? (for example positions of certain objects so that the shader could create some kind of ripples etc)

bobus_mogus

can one add a noise shader to a Light2D to simulate the small particles of dust in the air ( or equivelant ) ? thanks

mrstevens

А на каком языке пишуться эти шейдеры? Немного напомнило С++, нет?
What language are these shaders written in? Slightly reminded C ++, no?

КОД-шу

Seems so convoluted be to change timer and amplitude by drilling down into Materials. Is there a simple way to expose the shader uniforms vars in the properties of DancingGodot inspector

wyattbiker

How to save the material/shader resources in godot 3.1 ?

TheGruselmops

Somehow my preview rendering is iterating much slower than yours. Did I miss someting?

HunterR

Is this a good methode for huge bodies of water? (think top down oceans)

TheCivildecay

A pronúncia "certa" é 'perfórmances'.
