Simple Blur

shellrider

A super simple blur effect.

Use lod variable to regulate strength.

Shader code
shader_type canvas_item;

uniform float lod: hint_range(0.0, 5) = 0.0;

void fragment(){
	vec4 color = texture(SCREEN_TEXTURE, SCREEN_UV, lod);
	COLOR = color;
}

Anything that will cover the whole screen, so usually a ColorRect for example. This is because the shader in a screen shader, meaning it will use SCREEN_TEXTURE and SCREEN_UV

It should be “textureLod” instead of “texture” I believe.

“texture” also works for me.

how to do the same to a vec4 (like a shape made with code) instead of a texture?

For anyone getting an error in Godot 4, add this line above the fragment function to get it working: uniform sampler2D SCREEN_TEXTURE : hint_screen_texture, filter_linear_mipmap;

Alternatively, just swap SCREEN_TEXTURE and SCREEN_UV for TEXTURE and UV, respectively (I think, I could be wrong, feel free to correct me and explain why)

Edit: Ok yeah, I was wrong, disregard 😁
