Probe Relections on Other Renderlayers

[reepblue]

 

I was going to report this in the bug report, but I don't think this is really a bug. I noticed the reflections of my viewmodel (which were being rendered on a different layer) weren't reflecting the level probe. I suspected that this was because the probe is only set to renderlayer 1, and the example below proves this. It makes sense, but I expected the probes to affect all layers, but there might be a situation where you don't want that. 

The example and map attachment below demonstrates the conflict. I don't know what the best course of action would be. Should the probes render on all layers by default? Should there be an option to allow the mapper to set each entity to desired renderlayers? Or should this be left alone, and the programmer has to ensure the probes render on the desired renderlayers? 

#include "UltraEngine.h"
using namespace UltraEngine;

//#define TEMPFIX

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
    iVec2 windowsize = iVec2(1280, 720);
    WindowStyles windowstyle = WINDOW_CENTER | WINDOW_TITLEBAR;
    auto window = CreateWindow("Ultra Engine", 0, 0, windowsize.x * displays[0]->scale, windowsize.y * displays[0]->scale, displays[0], windowstyle);

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

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

    //Load the map
    WString mapname = "Maps/coloredroom.ultra";
    auto scene = LoadMap(world, mapname);

    auto maincamera = CreateCamera(world);
    maincamera->SetPosition(0, 1.28, -1.92);

    auto camera2 = CreateCamera(world);
    camera2->SetClearMode(CLEAR_DEPTH);
    camera2->SetMatrix(maincamera->GetMatrix(true), true);
    camera2->SetFov(maincamera->GetFov());
    camera2->SetRange(maincamera->GetRange().x, maincamera->GetRange().y);
    camera2->SetRenderLayers(2);

    auto sphere = CreateSphere(world);
    sphere->SetPosition(0, 1.28, 0);

    auto mat = CreateMaterial();
    mat->SetShaderFamily(LoadShaderFamily("Shaders/PBR.fam"));
    mat->SetRoughness(0);
    mat->SetMetalness(1);
    sphere->SetMaterial(mat);
    mat = NULL;

    sphere->SetRenderLayers(2);

#ifdef TEMPFIX
    // Search all probes
    for (const auto& p : scene->entities)
    {
        auto probe = p->As<Probe>();
        if (probe)
        {
            probe->SetRenderLayers(1+2);
        }
    }
#endif

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

    }

    return 0;
}

From your description, it sounds like the probes and render layers are working as intended? Is that correct?

[reepblue]

Yes (for the most part), but only after I figured out that the reflections were not showing on the viewmodel because it wasn't being rendered on the same layer as it. I'm not sure if this will add friction to new users.

In more recent testing, I've been getting black reflections when I changed the map without rebuilding the probes or in outdoor environments. I'd have to do more testing and make an example before I can file a bug report.

Perhaps by default lights and probes should have their render layers set so they include all possible values? (Max unsigned integer)

That's what I'm thinking unless there's any reason for that not need to be the case. I really think the RENDERLAYER enum should come back and allow us to assign renderlayers in the editor.
