Squash and Stretch Shader

Description

A squash-and-stretch spatial shader for Godot 4 that dynamically deforms 3D models. High-poly models produce smoother results.

You can also find this shader on Godot Shaders.

Shader Code

shader_type spatial;

uniform vec2 direction = vec2(1.0);
uniform float squash: hint_range(0.0, 2.0) = 1.0;
uniform float offset: hint_range(-0.5, 0.5) = 0.0;

void vertex() {
        float v = abs(VERTEX.y + offset) * squash + direction.x;
        VERTEX *= vec3(v, direction.y, v);
}
