JeffP: Journeyman: How did you make "water4.jpg"? AuntiAlias: welcome back, Journeyman. Clay was desscribing his lighthouse effect.. then you can address the water4 question Journeyman: k Rivak: . <- lurking still AuntiAlias: <pictures the flurry of typing on Clay's keyboard> Clay: I just lied to yall LOL!!!! I done that light differently oops AuntiAlias: === ; o Clay: well that effect is a cylinder set to fuzzy a high ambience and about half on the transparency but there are simple radial lights in there sheesh! (dork typin) but if I did wanna convert it to a light object AuntiAlias: That's a good point.... you can have an object that gives the appearance of your light source, and a light source actually casting the light. Clay: I wouold do that in the Mat Lab by making it a light then setting the volume on AuntiAlias: Clay's seems to be that. A cylinder that's a "stooge light" .. something we can see.. and then light sources that actually throw lights. The candles from earlier are that way. Spheres that have fire material preset on them (but also set to additive, Tonebone: How long do you think this chat will last? I have to log off and upload a piccie from my other PC, you might be interested in it.. AuntiAlias: so that they're brighter) and radial light placed in same place to throw the light Journeyman: a little while longer tony Tonebone: ok brb.. eilif: I've done that, Aunti Clay: I also like to use lights as part of an object, like the trails left by jet motors etc Journeyman: Another way to do it is thus: George told be able this anyway, what you do is get a sphere make it positive and glassy texture, then get a light and make it smaller, negative and then combine them he tells me it works well (you might like to experiment, I haven't had a chance to do it yet) eilif: neg? hm.. AuntiAlias: sounds interesting!! I"ve seen a link, I'll try to dig it up and post it eilif: might try that with mine... AuntiAlias: http://www.thespisonline.com/green.jpg Clay: here are two examples of the "secret cylinder Light" used as jet exhaust http://www.phase2.net/claygraphics/canyon12.html http://www.phase2.net/claygraphics/red_rock_run.html eilif: that's exactly what I was aiming at, the green jpg, but my light was pos! Journeyman: thank george next time you see him then AuntiAlias: neg light casts light shadow, eilif... Journeyman: here is an example of caustic light http://www.wheel-of-life.com/caustic.jpg eilif: but not light? I need to cast light on the person's face Journeyman: it neads a really ocean bottom there AuntiAlias: Clay.. secret cylinder light... is this where you take a cylinder and, in Materials Lab, shading mode menu set it to light, so that it fakes the light appearance (it looks like a light, but does not cast any light)? Clay: no Susan the light where you control+click on the square light when you're creating a light AuntiAlias: aaaah, that "secret" cylinder light! Clay: :-) AuntiAlias: the round parallel spotlight! Clay: yeah eilif: ? AuntiAlias: eilif? eilif: just for the stoopid, can I ask about that picture with the light ball? eilif: whether a negative light would've still given me light on his face? DreamVoyager: ? AuntiAlias: uh.. sure... but the person who created it is not here. That's george.... eilif: no, MY pic AuntiAlias: so you mean you want to have light emitting from a sphere that lights up someone's face, too? eilif: yes http://hjem.get2net.dk/eilif/new07.html Journeyman: just make a visible light put it inside a sphere maybe eilif: but the ball is not as good as george's... Journeyman: add a gel eilif: because that's what i did, what you said Clay: I would jst use a spotlight if ya want it just on the face AuntiAlias: or enlarge it outside sphere... depends on the sphere.... Croaker: Make a volume visible sphere light eilif: so one for the ball, one for the face, same color as ball? Clay: I would Journeyman: sounds good if you cant get it bright enough Clay: you could be more accurate I would think Journeyman: adding a spotlight on his face eilif: I want the light to be emitting from the ball eilif: or as if Tonebone: Back Journeyman: wb Tonebone: Can I give a link to a piccie? Journeyman: sure AuntiAlias: sure! Clay: use a fuzzy sphere that's set to volume and not surface or do you want "beams" shooting out? eilif: no beams Tonebone: Sice we are talking about lighting, I thought you might like to see this. It's still very much WIP. I have used negative lights in some areas of the room to tone things down a bit: http://www.tonebone.demon.co.uk/art/room1master2test.JPG DreamVoyager: ? eilif: just as is, only lightball like george's AuntiAlias: nice, Tone!! Tonebone: Thanks Susan :) eilif: very detailed! Croaker: Eilif, make a volume visible sphere light, it's simple Journeyman: very good Tony eilif: that's what it is, Croaker and a glass ball around it Clay: GREAT LIGHTING tbone! Croaker: U want it to be brighter then? AuntiAlias: tell us about the neg lites, tonebone! (still takin' it all in; it's a great image!!) eilif: brighter but more color, not a blob in the middle DreamVoyager: ????? (before we move on to Tonebone, please Tonebone: Thanks guys.. I'ts the first time I have used multiple lights :) eilif: I WANT THOSE BED SHEETS! sorry Croaker: Get rid of the sphere around the light then Tonebone: Sorry Dream !! AuntiAlias: sure, DV.. go for it DreamVoyager: Clay... the light eminating backwards from the motors... is that actual lightbeem from the cylinder parrallell spot? What are your settings, do you remember (aprox)? Clay: yes they are brightness set at 100% DreamVoyager: (BTW... I agree with the rest, ToneBone... stunningg pict. Too bad Poser still cant make good nudes.) Clay: and diffusion set to 10% DreamVoyager: aha fall off? Croaker: Tone, are those models from poser? Clay: ummm linear I think Cosmic_Cookie: Tonebone what program did you make the sheets in? DreamVoyager: aha, OK, thanks Clay. :-) Clay: N/P DreamVoyager: Im saticfied now... lets move on to toneBones wonderous apartment :-) Clay: here's a scene with just one light and the sun used for illuminating an object: http://www.phase2.net/claygraphics/thewaterclock.html Tonebone: models from poser, yes. Sheets made in Amapi. Not much to say re neg lights, just small squared falloff and cast no shadows! positioned in the darkest recesses of the room eilif: ? AuntiAlias: hmm! interesting! of course it makes sense.. neg lites can be squared or linear falloff... I think I need to do some tests for comparison of results : ) Thanks for joggin' the noggin, Tonebone! :D Tonebone: NP JPSullivan: Thank god that I now know that squared falloff is mathematically squared, and not geometrically squared, as I had thought all along... Tonebone: ooh, that sounds a bit technical! Clay: LOL!!
