Date: Fri, 12 Jun 1998 01:17:59 -0000 From: Stephen Thornber Subject: Quest: Lighting Probs Hi Guys. Question time. I've built a small space station (well more like a space depot actually. :) But I've having trouble lighting it. I want to have a few glowing lights near the docking entry, but can I do glowing lights... (NO I can't..!), also I've tried using controlled falloff for the lights, so they don't swamp the main lighting. But I can't get anything like glows or subdued lighting.. any ideas.... or is it a case of RTFM ..? :) ---------------------------------- Date: Thu, 11 Jun 1998 19:16:21 -0700 From: Rhithyn Yr Arth Got the "lens flare" FX going? This will give your lights a glow (mostly), but normally if you look at a light without any lensflare effects or objects to simulate the glow, you are SOL...they don't render themselves... ---------------------------------- Date: Fri, 12 Jun 1998 01:40:00 -0400 From: Collins Do you mean like a visible light itself? Have you tried using a sphere with fog, fakely, ghost and setting it to be a light? Or if you are using IFW 1.3 whatever, the ghost can be dropped for the settings in the fog tab of the attributes. I could upload an object but it would be the new IFW format, but I'm sure someone else could send you a sample glowing light object in the old format. Or maybe you mean you can't get the falloff right? If so, try a different falloff setting in the lights actor bar, if using stage lights. ---------------------------------- Date: Fri, 12 Jun 1998 19:20:21 +0200 From: Stephane Van Israel MMMh, If I remember Tom Grandberg's technique well, he used to create a very intensive light (intensity around 1500) with a limited fall off determined by the axis size and applied the lens flare global FX selecting only the halo around light axis tab. ---------------------------------- Date: Fri, 12 Jun 1998 12:27:46 -0700 From: Drift Dennis There is a way to get glowing lights, but it will cost you. As an example of the cost, I was rendering a pic for the contest, a ray trace took about 5 minutes on a ppro 200 with 128 megs. I added 1 glowing light, and it wasn't finished the next morning. Each light adds  a significant amount of time to render. How to do it? create a sphere, take color to black, specularity to white, near max on hardness and add some overdrive, filter to max, reflections set low (less then 25%). Make it a light source with shadows and point source, set it up otherwise the way you want it), copy this object, then scale it up by 20-50% (more or less), Then paste the original. Now both axis are at the same point, between the specularity and the small reflection you get a glowing light source. be sure to link them together. different colored light sources can inter play in interesting ways. ---------------------------------- Date: Sat, 13 Jun 1998 01:33:58 +0000 From: Andy Organization: Blurred Vision Maybe you could try Milans' Lensflare texture. It's a 3D texture which can be stuck on a cube or whatever. It makes a nice "glow" effect, and being 3D, it looks normal without needing to track it to the camera. Though It can do some nifty tricks iirc, like ramping the intensity depending on the angle of Y to the camera. Mayhap someone could jump in with the URL for Milans' site. I forgot it :] Mess about with fakely a bit. That can do the trick too. Jesus, ain't fakley a versatile texture. How would we get by with out it 8) Regards, ---------------------------------- Date: Sat, 13 Jun 1998 07:08:38 +0100 From: Matthew O'Neill Organization: Spectrum Take you light object, stick a spere of fog around it (start at about 300 and then take it down 20 at a time until it is the right thickness) then scale the y axis so that 1/3 of it is sticking out beyond the fog, and make sure that controlled falloff is used. Making them soft shadows should helo the effect too ---------------------------------- Date: Sun, 14 Jun 1998 12:07:57 -0400 From: Pat Connelly I tried the fog object but it did not seem to be my idea of a glowing light. I have fiddled with fakely and twinkle and come up with something. It is closer I think but not quite right. Any suggestions would be appreciated. http://www.erinet.com/fnadoc/imagine/temp/glow3.jpg ---------------------------------- Date: Mon, 15 Jun 1998 11:36:48 -0500 From: "Pyatt, Steve" Looks pretty good. What you can do is take a sphere. Make it a fog object with a length of .01. Add the Ghost Texture, then the Fakely texture. Pretty much go with the defaults on them. Tweak as desired. Make the object a light and render in trace. Should get a nice glowing light. Change the Fakely color as desired also. ---------------------------------- Date: Sun, 14 Jun 1998 13:08:27 -0400 From: Pat Connelly Thanks, Steve. It makes a very reasonably glowing sphere. I did not use the ghost texture on my previous fog objects and I think that is the answer. Also, it is a lot simpler than mine. ---------------------------------- Date: Mon, 15 Jun 1998 09:43:00 -0700 From: Clae & Deborah Tanett Hi Pat Major point for me... it's the color of the light on the ground; you have a yellow 'glow' with a 'white' cast. Try making the cast yellow to match the glow. ---------------------------------- Date: Sun, 14 Jun 1998 13:12:27 -0400 From: Pat Connelly Duh! Astute observation. I have been staring too hard at my light source and forgot about the light casting on the ground. I can fix that. Thanks Clae. ---------------------------------- Date: Mon, 15 Jun 1998 13:53:43 PDT From: Ian Stearns >I tried the fog object but it did not seem to be my idea of a glowing light. Hello.. take a look at http://www.geocities.com/SoHo/Studios/7772/buzzglow.jpg and see if any of these three glowing lights suit you. If any one does, i'll talk about it in greater detail. Left to Right: light 1 is fog with ghost.itx light 2 is fog with nebula.itx and overdrive (IFW 1.3.4+) light 3 is fog with just overdrive (IFW 1.3.4+) My only suggestion is to have the LIGHT COLOR match the FOG COLOR, since I see a yellow lightsource casting white light and it looks 'funny'. Good luck. ---------------------------------- Date: Mon, 15 Jun 1998 22:45:56 +0000 From: Andy Organization: Blurred Vision For stills, I use a "glow" a friend rendered for me with Lightwave. I compose it into the required area with photogenics, using the MIX/add filter. This composes the glow, and lights up the surrounding area. I'd use the solution I mentioned earlier in this thread for a animation. Oh yes. Regards, ---------------------------------- Date: Wed, 17 Jun 1998 14:02:22 -0500 From: Jeff Krase I like the second light and maybe the third light, but the first looks funny. It looks a little more like a small embryo or a tadpole before it's hatched or something. The second light looks like a stage light and the third light looks a bit like a distant sun. Anyone have any interesting ideas for how to use the first light? I wouldn't mind seeing more detail on all of the lights. Thanks in advance, ---------------------------------- << You can find the buzzglow.jpg and the Glow3.jp in the Threads/Additional Directory >>
