Subject: How do I get an object to become a light?

Easy question for someone, I'm sure.

I have the attached render. I need to have the ball emit light and preferably in the shade the spheres (I'll have a number of them in different colors) are overlayed with.

The sphere is one of BB's orbs. I have Poser 9.

Thank you for any help.

well at least

  1. switch on Indirect Lighting in Render Settings

  2. give the ball a material with something attached to Ambient Color, and a nice value (0.5 or up) to Ambient Value.

the latter will make the object glow, then the first will treat glow as a light source. Everything beyond that is experimenting, searching forum threads for more details, and so on.

Usually I'm wrong. But to be effective and efficient, I don't need to be correct or accurate.

I had Poser 5 for a long time and I set the sphere to not cast shadows, and put a spotlight inside it, set the light to the color you want. In Poser 7 and up you could use a point light.  Its a fake but its quick to do.

Thanks **aRtBee**, but I'm a novice at working in the advanced Material room. Could you tell me further what exactly I should do with your point #2?

"2) give the ball a material with something attached to Ambient Color, and a nice value (0.5 or up) to Ambient Value."

I get the Ambient Value but what material are suggesting that is attached to Ambient Color? And what node should I attach to it? Using Relect (as seen in the attachment) doesn't do anything that I can see. It makes it brighter but doesn't give it the impression it's giving off light.

markschum, I'll try that but doesn't the orb have to be transparent for the light to emit from it? And if so, how do I do that and still maintain the material color attached to it so it is not faded?**

I mainly intended to say: use the Ambient Color, and don't leave it black. The cyan itself is fine, for the moment, even without any nodes attached. Attaching nodes should be done with care, and please do use the ones you understand. An image map for instance, the bright areas will then glow and the dark ones will not, in the colors you like (multiplied by cyan in this case). Perhaps the info now plugged into Transparency can be connected to Ambient Color, or inverted first, depending on whether you want the transparent or opaque areas to glow. Just an idea.

And...when Ambient Value =1 does not produces enough light, you need to "pump up the volume". Some situations need values over 20, or more... Just try.

(The reflect node will reflect objects from the environment. This requires such objects to be available in your scene, and you should want that in your result. If no objects are around then this node produces a mild grey, just darkening the cyan. In real life, I'm not very familiar with lights which reflect their environment, to say the least).

here are the settings for using a point light in the ball.

shadows off in the ball parameters unless you have transparency.

color applied to the light  and the ball, with ambient on the ball to give the glow appearance.

 

aRTBee's method is likely better in later versions of Poser.

and the settings - only one point light in the above render.
