ivanjay Posted October 24, 2010 Share Posted October 24, 2010 Hi all, I modeled a 2' x 2' recessed light fixture and am just not happy how it is looking. I traditionally do all of my modeling in CAD so this was a bit new to me. I think the issue is more with my light output and material settings but can anyone guide me on how to improve this look. On the attached rendering you will see the fixtures in one row (I just put them in 1 row for testing). Attached is also what I am attempting to model. Thanks!!!

DavidR Posted October 25, 2010 Share Posted October 25, 2010 Not sure if you're just rendering or doing lighting analysis, but normally, I'd just stick Vray lights (or mr, etc) 12x12 or whatever, with maybe a plane the same size with a glow applied. It will render faster, the glow gives you the look while the light generates 90% of the light -don't crank up the multiplier of the glow material or you'll start to get white dots or other problems. If you need to use ies lights, my understanding (I don't use them) is that the light they cast is consistent with the light type AND it's fixture, so again you probably don't need to model the fixture. Esp. for an indoor scene, a photo would likely show all your lights as just white glows with no discernable fixture detail, so I think you're cleared to cheat!

I do know that a camera would not show the detail of the fixture but the human eye would see it. It is minutia but I always find that the extra level of detail with respect to those types of items does really bring a space to life. Traditionally I create the lights as you see in the other fixtures, just a square light with the option to show the light checked. In this case we are specifying a specific fixture and it would be nice to show it. Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted October 25, 2010 Share Posted October 25, 2010 I would recommend isolating that light, and posting a link here for others to look at your setup. The main problem I see is that whatever you are doing with the actual light is not working. Your curved up deflector is not casting a shadow, but letting light pass right through it. Are you placing a light inside of the fixture, and trying to get it to behave as though it would in real life? If so, don't. Typically for something like this I would place a light casting material in the deflector to make the inside of the light illuminated, and then place a separate IES light pointing down a couple inches underneath the light. The only potential problem with this is that is requires a bit more skill to get mr to render material lights smoothly. You may need to crank up the FG settings on the material that the light case is made of. Vray tends to handle the specific method I described much better imo.
