Idea

Here's an example script for the creation of a grid of lights for a view. To run it you should first right click the view background and choose "View->Desginate This View (sv)" and alter any of the commented values to suit your need.

It seems the more lights you have, the slower the rendering will be.

treenode view=sv();   //right click the view background and choose set as sv()
Vec3 startloc=Vec3(-10,-10,20);   // the SouthWest most corner of the lighting grid (min x and y)
double xsize=20;      //  grid x size
double ysize=20;      //  grid y size
double brightness=0.01;  // brightness per light
int spacing=2;            // grid spacing
double x0=startloc.x;
double y0=startloc.y;
double z0=startloc.z;
int lightidx=0;
double x;double y;
treenode lights=viewlights(view);
treenode light=lights.first;
while (lights.subnodes.length>1)
    lights.last.destroy();
for (int xidx=0;x0+xidx*spacing<x0+xsize;xidx++) {
    for (int yidx=0;y0+yidx*spacing<y0+ysize;yidx++) {
        lightidx++;
        x=x0+xidx*spacing;
        y=y0+yidx*spacing;
        if (lightidx>1)
            light=createcopy(light,lights);
        light.name="Light Source "+lightidx;
        light.subnodes[1].value=x;
        light.subnodes[2].value=y;
        light.subnodes[3].value=z0;
        light.subnodes[4].value=brightness;
        light.subnodes[5].value=brightness;
        light.subnodes[6].value=brightness;
        light.subnodes[7].value=0;        
        light.subnodes[8].value=0;        
    }
}

Note that with good settings for RTX, the lights may be incorrect for non-RTX viewing - requiring more ambient light to correct which is not ideal. The whole system needs calibrating or an exposure/gamma setting adding.

Also note that if you close the view you lose the light setting since it's not currently stored with the model - is the view window that contains the definitions. Because of this you may/not want to set it as the default view.
