Realistic office lights

[Carrotious]

WIP for an office refurb. My ceiling lights are crap. I have no idea how to go about making them look real. Any ideas. I'm just using a self illuminated material with a VrayMtlwrapper. For some reason that doesn't even com out looking bright. It's all rather shite. Would appreciate any help on how to get really nice lights with highlights and reflections off the metal structure within the lights etc.

 

Also where my floor is timber the reflected light (i think) is turning everthing yellow. any ideas how to reduce this. I tried making my light bluer but with little effect

 

Thanks for any help, am tired and the deadlines are way too short.

i'm not familiar with VrayMtlwrapper, but i know just using a standard material has always worked great for me on those kind of lights. i just get a standard material, and check self illumination and instead of puting in a value for the self illumination i check color and then select white.

 

the metal framing around the lights, try another standard material and crank the specular to like 90-95 and leave the color at the grey it defalts to, but you could make it a bit whiter.

 

your wood flooring shouldn't be effected too much by the color of the light. i think it would mainly change by the specular levels. keep it under 30 maybe even under 10. is it a polished floor? if so add some reflection to it. same with the table and the wood cubicle deviders on top of the desks.

although it is dependant on what type of lights you are using for the scene...i've had the best results with the vray lights and the invisible turned off...or sometimes a box light with the vray lightmat applied...play with the multi to get the right brightness.

Thanks, will try both. Never used a Vray light material so i guess its about time.

 

The problem with the timber floor is not the floor itself but the yellow light cast on the walls and cieling. i've atachd another file from the same project and you can really see the problem.

 

Thanks again.

Re: the lights, usin a standard max light with self illumination is fine but also add an output map in the difffuse slot and use the rgb spinner to control intensity.

 

re: the colour bleed, reduce the saturation in the GI roll out in Vray, 0.7 works well for me.

 

you might have too much light energy in the scene, maybe best reducing it a little and using exponential colour mapping to reveal a better GI result.
