LMP isn't really a defined file format. This particular file reports that the width and height are both -1...

What is bigbox.lmp? Is it the background image?

It was just an example. LMP are for UI images in Quake. I need weapon icons from rerelese pak0.pak (gfx/weapons). Currently have to keep ported icons in game folder.

Okay, I think it will work now. Update is available.

#include "UltraEngine.h"

using namespace UltraEngine;

    //Create user interface
    auto ui = CreateInterface(world, font, framebuffer->size);

    //Create widget
    iVec2 sz = ui->root->ClientSize();
    auto button = CreateButton("Button", sz.x / 2 - 75, sz.y / 2 - 15, 150, 30, ui->root);

    auto plg = LoadPlugin("Plugins/FITextureLoader");

    Assert(pixmap);
    
    ui->root->SetPixmap(pixmap);

    //Create camera
    auto camera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    camera->SetPosition(framebuffer->size.x / 2, framebuffer->size.y / 2, 0);

    while (true)
    {
        while (PeekEvent())

            const Event ev = WaitEvent();

                {
                    return 0;
                }
                break;
            default:
                ui->ProcessEvent(ev);
                break;

        }

        world->Update();

After update still an exception thrown, with other lmp files too.

[Josh]

You updated project to get the plugin?

[Josh]

I uploaded it to the wrong folder. Try again please.

[Dreikblack]

Thanks! Now it's working!

[Dreikblack]

btw the editor still crashing when i'm trying to open .lmp file (probably i don't really need it, just letting you know).

[Josh]

Are you sure?

[Dreikblack]

Was a case for me Updated and tried again today - now works,
