Hello

I have problem thats my light point emmision is only a half of circle and i dont know how to fix it :/
I use fallowing code with Alia5 LTBL2:

Code: [Select]

#include "ltbl/lighting/LightSystem.hpp"
#include <SFML/Graphics.hpp>
#include <iostream>


int main() {
    sf::RenderTexture normal_texture_;
    sf::RenderTexture specular_texture_;
    sf::RenderWindow window{sf::VideoMode{800,600}, "LightShow"};
    ltbl::LightSystem lightSystem{normal_texture_,specular_texture_,true};
    lightSystem.create({ -1000.f, -1000.f, 1000.f, 1000.f }, window.getSize());


    sf::Texture pointLightTexture;
    pointLightTexture.loadFromFile("resources/pointLightTexture.png");
    pointLightTexture.setSmooth(true);


    auto* light = lightSystem.createLightPointEmission();
    light->setTexture(pointLightTexture);
    light->setOrigin(pointLightTexture.getSize().x / 2.f, pointLightTexture.getSize().y / 2.f);
    light->setScale(10.f,10.f);


    while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed) {
                window.close();
            }
        }
        sf::Vector2f pos(sf::Mouse::getPosition(window));
        light->setPosition(pos);


        window.clear(sf::Color::White);
        lightSystem.render(window);
        window.display();
    }
    return 0;
}any tips?

edit: dummy me
 ltbl::LightSystem lightSystem{normal_texture_,specular_texture_,FALSE};
