Sprite with pixmap

[Dreikblack]

When i'm trying to create Sprite with Pixmap texture it's invisible. Label and usual Sprites can be seen

#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 * 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 light = CreateBoxLight(world);
	light->SetRange(-10, 10);
	light->SetRotation(15, 15, 0);
	light->SetColor(2);

	//Create camera
	auto camera = CreateCamera(world);
	camera->SetClearColor(0.125);
	camera->SetPosition(0, 0, -3);
	camera->SetFov(70);

	auto default_font = LoadFont("Fonts\\arial.ttf");
	auto ui = CreateInterface(world, default_font, framebuffer->GetSize());
	ui->SetRenderLayers(2);
	ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);
	auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
	uiCamera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0);
	uiCamera->SetRenderLayers(2);
	uiCamera->SetClearMode(CLEAR_DEPTH);

	auto label = CreateLabel("TEST GUI LABEL", 100, 100, 100, 50, ui->root);

	auto pixmap = CreatePixmap(iVec2(100, 100)); 
	pixmap->Fill(Vec4(0.5f, 0.5f, 1, 1));
	auto tex = CreateTexture(TEXTURE_2D, 100, 100, TEXTURE_RGBA, { pixmap }, 1, TEXTURE_CLAMP_UV);
	auto mtl = CreateMaterial();
	mtl->SetTexture(tex);
	mtl->SetShadow(false);
	mtl->SetTransparent(true);
	mtl->SetShaderFamily(LoadShaderFamily("Shaders/WidgetBlock.fam"));

    auto sprite = CreateSprite(world, 0, 0);
    sprite->SetPosition(0, 0);
  //  sprite->SetViewMode(SPRITEVIEW_BILLBOARD);
	sprite->SetMaterial(mtl);

	sprite->SetRenderLayers(2);
	//Create usual sprite
    auto sprite2 = CreateSprite(world, 2, 2);
    sprite2->SetPosition(2, 0, 0);
    sprite2->SetViewMode(SPRITEVIEW_BILLBOARD);

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

    return 0;
}

    return 0;
}

2 Things:

1. I believe the WidgetBlock Family is not the right one, better use the unlit family for this.
2. your sprite with the material has a size of 0,0 so it will never be displayed no matter what you try to do

auto pixmap = CreatePixmap(iVec2(100, 100));
	pixmap->Fill(Vec4(0.5f, 0.5f, 1, 1));
	auto tex = CreateTexture(TEXTURE_2D, 100, 100, TEXTURE_RGBA, { pixmap }, 1, TEXTURE_CLAMP_UV);
	auto mtl = CreateMaterial();
	mtl->SetTexture(tex);
	mtl->SetShadow(false);
	mtl->SetTransparent(true);
	mtl->SetShaderFamily(LoadShaderFamily("Shaders/Unlit.fam"));

	//Create pixmap sprite
	auto sprite = CreateSprite(world, 40, 40);
	sprite->SetPosition(20, 20);
	//sprite->SetViewMode(SPRITEVIEW_BILLBOARD);
	sprite->SetMaterial(mtl);
	sprite->SetText("Test");
	sprite->SetRenderLayers(2);

with these changes the colored sprite is visible in the lower left corner.
