Simple Parallax Material Scrolling

How to use:

Convert the material with texture albedo to a shader, then copy and paste the code below and add to the code you just created. 

Shader code

uniform vec2 scroll_speed = vec2(0.2, 0.0); // Default scroll to the **left** at 0.5 units/sec

void vertex() {
    // Apply initial UV scaling and offset
    vec2 scaled_uv = UV * uv1_scale.xy + uv1_offset.xy;

    // **Apply scrolling based on TIME and scroll_speed**
    scaled_uv += scroll_speed * TIME;

    // Assign the modified UV to be used in fragment shader
    UV = scaled_uv;
}

void fragment() {
    vec2 base_uv = UV;

    vec4 albedo_tex = texture(texture_albedo, base_uv);
    ALBEDO = albedo.rgb * albedo_tex.rgb;

    float metallic_tex = dot(texture(texture_metallic, base_uv), metallic_texture_channel);
    METALLIC = metallic_tex * metallic;
    SPECULAR = specular;

    vec4 roughness_texture_channel = vec4(1.0, 0.0, 0.0, 0.0);
    float roughness_tex = dot(texture(texture_roughness, base_uv), roughness_texture_channel);
    ROUGHNESS = roughness_tex * roughness;

    // Emission: Enabled
    vec3 emission_tex = texture(texture_emission, base_uv).rgb;
    // Emission Operator: Add
    EMISSION = (emission.rgb + emission_tex) * emission_energy;
    ALPHA *= albedo.a * albedo_tex.a;
}
