I do not understand what the purpose of scene0 in the above example is. I changed the code and it now works as I would expect.

The scene file format currently does not embed procedurally created model geometry into files. All models must be loaded from a file. This might be something we change in the future, but for now that is part of the design. 

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

    //Create a world
    auto world = CreateWorld();

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

    //Create a camera    
    auto camera = CreateCamera(world);
    camera->SetClearColor(0.125);
    camera->SetPosition(0, 1, -4);

    //Create light
    auto light = CreateBoxLight(world);
    light->SetRange(-10, 10);
    light->SetArea(15, 15);
    light->SetRotation(45, 35, 0);
    light->SetColor(2);

    //Create the ground
    auto ground = CreateBox(world, 20, 1, 20);
    ground->SetPosition(0, -0.5, 0);
    ground->SetColor(0, 1, 0);

    //Create a scene
    auto scene = CreateMap();
    scene->AddEntity(ground);
    scene->AddEntity(light);
    ground = NULL;
    light = NULL;

    //Add some boxes
    for (int n = 0; n < 2; ++n)
    {
        auto box = CreateBox(world);
        box->SetColor(0, 0, 1);
        box->SetPosition(Random(-5, 5), Random(5, 10), Random(-5, 5));
        box->SetMass(1);
        scene->AddEntity(box);
    }

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        if (window->KeyHit(KEY_A))
        {
            auto box = CreateBox(world);
            box->SetColor(1, 0, 1);
            box->SetPosition(1, 1, 1);
            box->SetMass(1);
            scene->AddEntity(box);
        }
        if (window->KeyHit(KEY_D))
        {
            for (auto box : scene->entities)
            {
                if (box->As<Model>())
                    scene->RemoveEntity(box);
                break;
            }
        }
        if (window->KeyHit(KEY_S))
        {
            //Save the scene to a file
            scene->Save(GetPath(PATH_DESKTOP) + "/game.sav");
        }
        //Load the scene when space key is pressed
        if (window->KeyHit(KEY_SPACE))
        {
            scene = LoadMap(world, GetPath(PATH_DESKTOP) + "/game.sav");
        }

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

By saving nothing? :D

If i change boxes to brushes, they fall through ground brush but now being saved, but lightning is broken after load.

I think we probably need a flag or save command that saves the state of objects without resaving the brush and other data. It seems like saving a scene is not exactly like saving a scene...

What I meant to say is that saving a game state is not exactly the same thing as saving a scene. :blink:
