Bounds not calculating

[SpiderPig]

The bounds are returning 0 size for some objects I'm loading.  I think its when there are two or more entities in the file.  Here cube1 shows the correct bounds size but cube2 (has two cubes in it) returns 0.

#include "Engine.h"
using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    auto displays = GetDisplays();
    auto window = CreateWindow("Ultra Engine", 0, 0, 800, 600, displays[0]);
    auto world = CreateWorld();
    auto framebuffer = CreateFramebuffer(window);

    auto camera = CreateCamera(world);
    camera->SetClearColor(0.0f, 0.0f, 1.0f);
    camera->SetFov(70);
    camera->SetRange(0.01f, 1000.0f);
    camera->SetPosition(0, 1, -3);

    auto light = CreateDirectionalLight(world);
    light->SetColor(5.0f);
    light->SetRotation(35, 45, 0);

    auto font = LoadFont("Fonts/arial.ttf");
    auto ui = CreateInterface(world, font, framebuffer->size);
    ui->SetRenderLayers(2);
    ui->root->SetColor(0, 0, 0, 0);

    auto ui_cam = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    ui_cam->SetPosition(framebuffer->size.x / 2, framebuffer->size.y / 2, 0);
    ui_cam->SetRenderLayers(2);
    ui_cam->SetClearMode(CLEAR_DEPTH);

    auto label = CreateLabel("", 10, 10, 200, 30, ui->root);

    auto cube1 = LoadModel(world, "Cube.gltf");
    auto cube2 = LoadModel(world, "Cube2.gltf");
    auto b1 = cube1->GetBounds();
    auto b2 = cube2->GetBounds();

    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        label->SetText("Size1 : " + String(b1.size.x) + ", " + String(b1.size.y) + ", " + String(b1.size.z) + "\n"
            "Size2 : " + String(b2.size.x) + ", " + String(b2.size.y) + ", " + String(b2.size.z));

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

Without looking at it, I am guessing box2 has a node at the top of the hierarchy with no geometry, so it's just a point. You can get the recursive bounds and that will include all the children.

Ah yes.  That did the trick.
