Custom sun ray colour not working

Hokan · 07-22-2015 07:48 PM

As title - if I create custom sun via SunClass constructor (reason - I want to have two suns), its ray_colour member won't affect sun's rendering. BUT this works with so called "Main Sun" - global "Sun" variable.

Code:

vigilantEye.sun.image = UID(2922889087, 1171051764, 3010789764, 3570309810); // Images/sun

vigilantEye.sun.size = 0.05;

Vec lightColour(255, 242, 161);

lightColour /= 255;

/**********************************************/

Vec raysColour(171, 171, 171);

raysColour /= 255;

vigilantEye.sun.rays_color = raysColour;

/**********************************************/

Vec imageColour = lightColour * 255;

vigilantEye.sun.light_color = lightColour;

vigilantEye.sun.image_color.set(imageColour.x, imageColour.y, imageColour.z);

vigilantEye.sun.glow = 255;

vigilantEye.sun.highlight_front = 0.275;

vigilantEye.sun.highlight_back = 1.0;

How it suppose to work (as Sun parameter of Environment):

How it works in application (to the right glowing of Editor's sun):

So my questions are:
1. Is there an option to make "rays_color" work on custom suns?
2. Is it a bug or native behavior (and Engine renders external Sun specificly)?
3. If it is a bug, will it be fixed or is it fixed? (I'm using version from Feb.'15)

Ray colour should be the colour of the sunlight going through/around objects. That's not visible in your example.

Ok, maybe "rays_color" describe god rays (and not "light_vol", "light_vol_exp" and "light_vol_steam" parameters), but as you see it also describe sun's light source brightness, and it's working for main sun.
