Point light question - star light simulation Software: Away3D 4.x

kz, Newbie Posted: 27 January 2012 04:36 PM Total Posts: 30 Hi, I’ve attached an image: I got this “sun”, I’d like the point light to illuminate the silver rings on the INSIDE, but I can’t. I tried with radius and fall’off but I still don’t get it. Any suggestion? `light = new PointLight(); light.color = 0xff0000; light.radius = .001; light.fallOff = .5; light.diffuse = 1; light.specular = .3; addChild(light);` Thanks in advance (:

Also you adjust each material how to interact with the light. Start from there… ringsMaterial.lights = [light]; ringsMaterial.specular = 0.5;

I haven’t done any specific test with lights, just the basic lightning of a scene, so not 100% sure how they behave in away3d. But 1 thing I could think of that can cause trouble in some engines is you putting the light in the middle of the ball, which might contain the lightning, therefor no light comes out. Try the scene without the ball or putting the light beside it. Also, if you want a shining star in the middle I would go with billboard (or animated billboard) rather than geometry (sphere). I’m not sure away3d has a method to make a geometry luminous like a star.

Cant get the sphere to be displayed. ››
