Linear Fluorescent IES Light

harnstein · 16 Dec 2010, 13:35

Hi,

it's good to work with IES lights, we all know.

But what about linear ies lights? I found some files, but how can i use them?

Like e.g. for a stroke of light under the ceiling made of fluorescent T8 tubes.

If i load an ies file for linear fluorescent into vray, all i get is still a spot.

Even if i change the ies-light-component-cone into a linear box- which is not a surprise, i know..

Any ideas?

Hi,

I've also been facing this same problem. I've tried changing the ies light geometry but that didn't help in any way.
Have you found any solutions?

Have you asked ASGVis support?

שׁAnswers in the sketchucation forum are usually quicker and more to the point, But I posted the question there too now.

I think this is a more specialised question that they would answer better. Might even be a bug - in which case they need to know about it.

No. IES lights currently are point lights like the spotlight and omni-light. I mentioned having an option for linear ies light source in the wishlist thread a little while ago. I don't know how involved it would be (or how high a priority) it is from the developer end.

That's good to know! Thanks Thom!

just the ordinary one- modelling a tube with the right dimensions and adding an emissive material.

as far as there are no linear ies lights in sight, maybe we should build a library on our own. if i find the time i will share some. warm / cold light color, different watts, sizes etc.

is it possible to save a "vray-component" to the warehouse? i mean, does it save the information of the emissive vray material? (i never did before.. )

does anybody know how to interpret the "intensity" value in the emissive-layer-dialog?

if i look at the data of e.g. philips lights there is always light color/temperature, lumens/candela and watts- if i dont miss something.

how to compare that to "intensity"?

If you use version 1.48.xx

ok, thanks.

if you know how to interpret the "intensity" thing please let me know..
