Materials for map can't be load from zip

[Dreikblack]

After recent update material for skybox can't be loaded from zip package

1. Make Materials.zip with Materials folder inside

2. Rename usual Materials folder to exclude loading from non-package

Standard start.ultra map

#include "UltraEngine.h"
#include "ComponentSystem.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    RegisterComponents();

    auto cl = ParseCommandLine(argc, argv);

    //Load FreeImage plugin (optional)
    auto fiplugin = LoadPlugin("Plugins/FITextureLoader");

    //Get the displays
    auto displays = GetDisplays();

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

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

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

    auto package = LoadPackage("Materials.zip");
    package->FileType("");

    //Load the map
    WString mapname = "Maps/start.ultra";
    if (cl["map"].is_string()) mapname = std::string(cl["map"]);
    auto scene = LoadMap(world, mapname);

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

    return 0;
