Panel texture not showing with 3D cam

[SpiderPig]

While the example here works, it seems if you are overlaying an interface over a 3D environment the panel won't show the assigned texture.  I first noticed this in my project where I wanted to show the real-time render of a 2nd camera on the panel.

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0]);
    auto framebuffer = CreateFramebuffer(window);
    auto world = CreateWorld();
    auto font = LoadFont("Fonts/arial.ttf");

    auto ui = CreateInterface(world, font, framebuffer->size);
    ui->background->SetColor(0, 0, 0, 0);

    //Create and position camera
    auto camera = CreateCamera(world);
    camera->SetPosition(0, 1, -2);

    int RENDERLAYER_1 = 2;
    auto ui_camera = CreateCamera(world, UltraEngine::PROJECTION_ORTHOGRAPHIC);
    ui_camera->SetRenderLayers(RENDERLAYER_1);
    ui_camera->SetPosition(framebuffer->size.x / 2.0f, framebuffer->size.y / 2.0f);
    ui_camera->SetClearMode(UltraEngine::CLEAR_DEPTH);

    auto panel = CreatePanel(0, 0, 512, 512, ui->root);
    auto tex = LoadTexture("https://raw.githubusercontent.com/UltraEngine/Documentation/master/Assets/Materials/Ground/river_small_rocks_diff_4k.dds");
    panel->SetTexture(tex);

    auto box = CreateBox(world);
    box->SetColor(1, 0, 0);

    while (true)
    {
        while (UltraEngine::PeekEvent()) {
            auto event = UltraEngine::WaitEvent();
            switch (event.id) {
            case UltraEngine::EVENT_WINDOWCLOSE:
                if (event.source == window) {
                    return 0;
                }
                break;
            }

            ui->ProcessEvent(event);
        }

        world->Update();
        world->Render(framebuffer);
    }
    return 0;
}

I fixed it 

auto ui = CreateInterface(world, font, framebuffer->size);
ui->background->SetColor(0, 0, 0, 0);
ui->SetRenderLayers(RENDERLAYER_1);//<----- Needs this!!
