    Additional lighting in engine

    the hard limitation was the engine not yet making it possible to define light sources attached to units or map props.

    It's not the hardest part. The most time consuming part is to make the lights be accounted during rendering.

    PRB would be awesome but feels more secondary by comparison: Especially for a RTS where you don't see close detail it might be less immediate.

    PBR isn't for details but for rendering consistency. With PBR an object will look well in all light conditions. Currently we have over-brighten or over-darken colors on some maps.

    Some guidance?

    Currently we have at least two major problems: many different materials (different only by uniform value aren't different) and many draw calls (because of complex variations).

    I also plan to release Technical Art Guide but not sure when I'll have time to finish it.

    you mean to look at patches by this guy https://code.wildfiregames.com/D3555 ?

    No, I mean industry standard PBR approaches.

    May I bump this to ask if any progress has been made since last time? Alpha 26 was released recently: A27 is about to be upgraded from OpenGL and feature a Vulkan backend. Given the new renderer, is the way paved for allowing buildings / units / map decorations to correctly have their own lights?

    Technically it's possible but it requires art optimization.

    I feel the lack of custom light sources is the biggest relevant limitation still left in Pyrogenesis.

    I can't say it's the only biggest there is also PBR.

    On both systems I was running 0ad from an AppImage. On the desktop it worked.

    Could you run the following test program? 

    #include <iostream>
 
#include <SDL2/SDL.h>
 
int main()
{
    if (SDL_Init(SDL_INIT_VIDEO|SDL_INIT_TIMER|SDL_INIT_NOPARACHUTE))
    {
        return -1;
    }
    const int flags = SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE | SDL_WINDOW_VULKAN;
    SDL_Window* window = SDL_CreateWindow("vk-test", 10, 10, 512, 512, flags);
    if (window)
    {
        std::cout << "success" << std::endl;
        SDL_DestroyWindow(window);
    }
    else
    {
        std::cerr << "fail: " << SDL_GetError() << std::endl;
        return -1;
    }
    return 0;
}

    Command to run: 

    g++ -O2 --std=c++17 vk-test.cpp -o vk-test -lSDL2 -I/usr/include/SDL2 && ./vk-test

    For instance shore waves are rendered in gl without fancy while it requires fancy with vulkan

    I think it's not the expected difference.

    also using vulkan models throw shadows onto themself while in gl only onto other objects.

    Could you show an example?

    Do you have an inkling of what is going on there?

    Highly likely it's related to material refactorings. I'll investigate it further.

    Should I report here some logs

    You might attach errors about a "model_solid_tex" material.

    it works quit well!

    Did notice any difference with OpenGL?

    automatic data upload system is enough for you?

    If you enabled Feedback in the main menu then it should be enough.

    Texture or shader quality doesn't change anything.

    Any other option maybe?

    My GPU memory usage is at 2GB when it crashes.

    It might mean limitation of 32bit application. Your GL crash says: "JavaScript error: out of memory", which means out of available RAM. Highly likely it's the same reason for Vulkan. Might want to build with --large-address-aware.
