Voxel Shader

MountainLabs

A sudo working voxel shader

Shader code
shader_type spatial;

uniform float voxel_size : hint_range(0.01, 1.0) = 0.15; // Size of each voxel

void vertex() {
    // Get world position of the vertex
    vec3 world_pos = VERTEX * mat3(MODEL_MATRIX) + MODEL_MATRIX[3].xyz;

    // Snap to voxel grid
    world_pos = floor(world_pos / voxel_size) * voxel_size;

    // Convert back to object space
    VERTEX = (inverse(MODEL_MATRIX) * vec4(world_pos, 1.0)).xyz;
}

I made some adjustments that fix some world position errors and also adds texture input

shader_type spatial;

uniform float voxel_size : hint_range(0.01, 1.0) = 0.15; // Size of each voxel
uniform sampler2D color : hint_default_white;

void vertex() {
  // Get world position of the vertex
  vec3 world_pos = VERTEX * mat3(MODEL_MATRIX) + MODEL_MATRIX[3].xyz;

  // Snap to voxel grid
  world_pos = floor(world_pos / voxel_size) * voxel_size;

  // Convert back to object space
  VERTEX = (MODEL_MATRIX * vec4(world_pos, 1.0)).xyz;
}

void fragment() {
vec3 alb = texture(color,UV).rgb;

ALBEDO = alb;
}
