Second Coord Set Not Working

[SpiderPig]

Here's a quick program and shader to test this out.  The shader works with inTexCoords.xy but not with inTexCoords.zw.

#include "UltraEngine.h"
#include "Components/Mover.hpp"

using namespace UltraEngine;


int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);
    auto world = CreateWorld();

    //Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create a camera
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetFov(70);
    camera->SetPosition(0, 0, -3);

    //Create a light
    auto light = CreateBoxLight(world);
    light->SetRotation(35, 45, 0);
    light->SetRange(-10, 10);

    auto box = CreatePlane(world);
    box->SetRotation(-90.0f, 0.0f, 0.0f);

    auto material = LoadMaterial("Materials\\Test.mat");
    box->SetMaterial(material);

    auto mesh = box->lods[0]->meshes[0];
    mesh->SetVertexTexCoords(0, 0.0f, 0.0f, 1);
    mesh->SetVertexTexCoords(1, 1.0f, 0.0f, 1);
    mesh->SetVertexTexCoords(2, 0.0f, 1.0f, 1);
    mesh->SetVertexTexCoords(3, 1.0f, 1.0f, 1);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

Shader :

#version 450
#extension GL_GOOGLE_include_directive : enable
#extension GL_ARB_separate_shader_objects : enable
#extension GL_EXT_multiview : enable

#include "../../../../../../../../UltraEngine/Templates/Common/Shaders/Base/TextureArrays.glsl"
#include "../../../../../../../../UltraEngine/Templates/Common/Shaders/Base/Materials.glsl"


layout(location = 5 ) in flat uint inMaterialIndex;
layout(location = 2 ) in vec4 inTexCoords;

layout(location = 0) out vec4 color[8];


void main() {
	color[0] = texture( texture2DSampler[ GetMaterialTextureHandle( materials[ inMaterialIndex ] , 0 ) ] , inTexCoords.zw );
}

Hey @Josh do you think this is a bug or is it just my bad shader skills?

The second UV set was not being copied into the mesh data.
