Light?

Light?

(OP)
hiya,

I'm trying to draw up a light design, only part of the light is on so I need that part to look on but the rest of the light not too? I've tried using a constant material (30% transparent) but the light looses it's shape? and a fog light behind but I can't get it to work? is there any other way?

I've got a picture of the design, if someone could explain how to attach it to a message?

Thanks

RE: Light?

Seems to me you should be able to add a light source.

Lighting Overview
You can adjust the direction, intensity, and color of light in the shaded view of a model. You can add light sources of various types, and modify their characteristics to illuminate the model as needed.

The properties of the light sources work with the material properties of the model. If you change material properties of the model, you can enhance or reduce the effect of the light properties.

Light Types
There are several types of light source:

Ambient light. Illuminates the model evenly from all directions. In a room with white walls, the level of ambient light is high, because the light reflects off the walls and other objects.

Directional light. Comes from a source that is infinitely far away from the model. It is a columned light source consisting of parallel rays from a single direction, like the sun.

Point light. Comes from a very small light source located at a specific coordinate in the model space. This type of light source emits light in all directions. The effect is like a tiny light bulb floating in space.

Spot light. Comes from a restricted, focused light with a cone-shaped beam that is brightest at its center. A spot light can be aimed at a specific area of the model. You can adjust the position and distance of the light source relative to the model, and you can adjust the angle through which the beam spreads.

RE: Light?

I can't find it right now, but someone posted a similar question to yours a few months ago.  Some else posted the answer with a few links to images, like a tutorial.  I think they used a point light to make a ball "glow".  Maybe whoever replied will reply here.

What the......is it groundhog day?

RE: Light?

(OP)
I already tried the stuff suggested in glowing parts, but I still can't seem to make it look good. when i make the ball a constant material, with transparency at 30, I can see all the workings inside? and it looks a little flat? is there any other way?

RE: Light?

You'll definitely need to use indirect lighting as a rendering setting.

If you want more depth (less "flat") to your part, create another transparent (but not constantly-lit) part like a layer of glass over your constant, partly-transparent part.  With this part you can better control gloss, reflectance, and other properties.  To get a good rendering, you'll need to turn up the number of reflections/refractions in the Options panel for PhotoWorks and the rendering will take a while to render.  You'll also need to turn up the indirect lighting option as well.

Doing these things will bring great results.

Theophilus- I had a go with the extra layer of glass - it worked a treat! Thanks
