I've known for a while now you could do boolean operations on lights, sometimes making funky stuff. Never ran across this simple one, until now. A single positive cube. A single negative radial light. (shown here with no light on) It drills out the cube as it should, but also...guts it. AS

That's a twisted mind you have, boolean lights!

That "gutting" effect is like what happens on imported geometry when you don't have the "Solid When Boolean Rendering" option checked.

You've got me thinking though - what would happen if you boolean a light with another light :-/

Well, it can apparently be used for various nifty things. Negative radial light, squashed, and an intersect sphere. The light is ranged as well as having a pretty dark gradient, too. Notice how the iris glow is nicely fuzzy, not like that artificial 100% Ambience. Unfortunately, I don't see a structure in it. I'll have to go case by case.

very interesting! drac

hmm..maybe you can do (offscreen) recessed lighting..negative light..hmm..is it possible to go 'faster than dark'?..;)

I wish I'd said that.. The Staircase Wit

In this image the light source is visible, being the sphere with a chunk taken out of it via a radial light. I find that this gives more accurate, concave lighting surfaces as you would get in a lamp with a reflector, as in bryce reflectors don't really reflect :)

YEah, but you did something with shadows, max. Cause mine such had a pretty sharp and visible shadow on the floor below it.

-- erlik

Soft shadows are enabled on all the lights, maxiumum softness. That image took 36 hours to render at 128 RPP LOL, I believe it has every advanced render option enabled in fact.

looks like you are working in a LDRI sphere as well, nice image max!

Pass no temptation lightly by, for one never knows when it may pass again!

I dunno what's going on here, but I did a bit of playing too, the left sphere is positive with a positive light (green) inside and a negative light (blue) half in and half out of the sphere and grouped with it. The right sphere is negative and so is the blue light inside it. The blue neg light is grouped with the right sphere. And the right sphere is grouped with the left sphere... I hope. The cube has had nothing done to it, not even a material - so I have no idea what's going on, but it's rather pretty... sort of. But I don't know if any of the effects you are talking about are present here...

@ AS....... I think this was how x-rays were discovered. Careful that you don't die prematurely of some light stroke. If two lights booleaned together, one positive and one negative and one set at positive light and other negative of same value; does it cancel out itself and simply isn't there? Or does a worm hole open up?

A worm hole pops open, and Kai Krause hands you Bryce 10.5 from the future. AS

hehehehe

So that's how you pull some of those images off eh?

Erlik, how on earth did you do that? - exactly I mean, since I've tried it myself and can't duplicate it.

I did get some nice effects though...
I tried a sphere booleaned with a radial light, and a cone booleaned with a smaller cone and then the results of those two booleaned together...
Plus using IBL and a water plane on top of an infinite plane with a slightly reflective surface, can't remember exactly what it was... but the odd thing is I prefer the reflection of the cone-ball thing on the water plane (which actually looks like wet streets rather than water alone) to the actual... um... cone-ball thingie itself.

My gosh, Fran has been in a worm hole.  If I'm reading the posting dates right it took a year for her to recover.  Or was the render that looooooooong?

Sorry Fran, I couldn't pass that up.

AS. You realise it would also have to come from a different solar system as well as a different time. By the time time B10.5 arrives the sun would have destroyed the inner solar system and be a little old brown dwarf.  That will take place in about 5 billion years. Far too short a time period for B 10.5 to be out.

When I was in the sixth grade some friends and I found an x-ray tube at the air force base dump.  So we rigged a power supply to fire it up and took x-rays on lithography film.  I feel sorry for the little critters that got sacrificed to the radiation gods.  It is a good thing that my friends brother got jealous and broke the tube or we could all have cancer now as we weren't using shielding.

Free men do not ask permission to bear arms!!

The last time I used something that Agent Smith suggested, I ended up getting an interesting picture. Took 5 days to render but it was something different from what I usually do.

So I am going to bookmark this page and see what I can do.

Fran, sorry, I didn't see this, as my site email was kaput. No, I don't remember anything more except that I used the eye material on the sphere and tried to make the booleaning light to be as big as the blue "iris" in the material. I also remember I had to make some effort with the exact positioning of the light. And I apparently didn't save the file. I have just that screenshot from a year aago.
