how to show the bulb lensflare effect when the bulb where in the transparant objects

Maybe someone know the right method, but from my experience i think that is not possible... You can see the effects only when the light have a little part out of your transparent object or when the point of view allow you to see the bulb, but i'm almost sure that isn't the effect that you need. BTW Good luck!! -TOXE

Sutoms, Put a bulb with brightness at 1% just outside the box in front of the object (uncheck CAST SHADOWS box) and activate the lens flare.. The low setting will not interfere with the lighting of the scene and it will show the lens flare. Do not drop the brightness to 0% as this just turns off the light, and consequently the lens flare. As far as I know, this is the only way to accomplish the effect. Light will pass through transparent objects, but the effects will not. Check a couple of threads back and you will see something about the refraction settings that seemed to be buggy. Same basic thing... Ken

cckens is right that it won't show through, but the reason is that lens flare, like blur and DOF, are post effects, so they happen AFTER the render. Since the bulb is already rendered it can't show the effect through the object. I believe it actually is happening, just only INSIDE the bulb! :>

You can fake a lens flare with Photoshop or some other image editing packages, as well, in post-render image manipulation. If it's an animation, you can render it as image sequences and add the flare in photoshop one frame at a time, or you can use an effects package like AfterEffects.... Unfortunately, Carrara's renderer doesn't realize that the lightbulb it's seeing through the transparent object (or reflected in a reflictive object, either) should also cause a lensflare....

I think it was EricofSD that put up a tut a long time ago for Bryce. The idea was to make a series of spheres that were so transparent that they were barely visable so many units apart coming towards your camera and let the light play off those. I think he incorporated a cone or cylinder as well. You might be able to get something decent this way in Carrara if you play with the shaders enough? cheers, - TJ

Not stupid; that's the one - I think with a little thought, the information will convert to Carrara, don't you?

You might be able to put a set of spheres in a line and use something like shader ops to get it to produce the disks in line from the source to the edge of the camera. I think it would be easier to take on the two light approach. For the animation aspect of it, you could group the two lights, put the hotpoint of the group at the center of the main light and add the "point at" behavior of the group to point at the camera. That way the "flare" light is always in line with the source light as the camera moves. For other post rendering effects, I've used a spot light set at 1 degree angle and pointed them at the camera. This removes the light the "effect" light is introducing into the scene because it's only shining on the camera. I usually do this in combination with a bulb light that has to be behind something. Seems to work fine. -Kix
