Pick collision and light does not work for Brush if it was parented to Pivot in the Editor

Light when not parented:

When parented:

Click to test pick collision. For some reason pick works if you click on box when ground is behind it, otherwise pick is not successful. I was not able to reproduce if i create brush and pivot via code.

#include "Leadwerks.h"

using namespace Leadwerks;

int main(int argc, const char* argv[]) {
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 1280, 720, displays[0], WINDOW_CENTER | WINDOW_TITLEBAR);

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

    //Create a world
    auto world = CreateWorld();
    shared_ptr<Camera> camera;
    auto scene = LoadMap(world, "maps/TestBox.map");
    for (auto entity : scene->entities) {
        if (entity->As<Camera>()) {
            camera = entity->As<Camera>();
            camera->SetDebugPhysicsMode(true);
            break;
        }
    }

    while (window->Closed() == false) {
        //Click on an object to change its color
        if (window->MouseHit(MOUSE_LEFT)) {
            auto mousepos = window->GetMousePosition();
            auto pick = camera->Pick(framebuffer, mousepos.x, mousepos.y, 0, true);
            if (pick.success) {
                pick.entity->SetColor(1, 0, 0);
            }
        }
        world->Update();
        world->Render(framebuffer);

    }
    return 0;
}

I recall bringing this issue up with the FPS Template and I was just told not to parent lights for the meantime, lol.

If the pivot is set to not cast shadows and uses NONE for the pick mode (as is the default), then the child light will not cast shadows or participate in pick operations.

[Dreikblack]

It works for shadows, but child is not pickable with Prop and Collider mode for both child and pivot

Okay, it was a problem with the recursive bounding box not getting updated when the box was pivoted to the parent. Thanks for reporting!
