IES,Vray light question

[Billabong]

I have these sidewalk street lamp post that I need to light. Can IES light these type of lampposts, and if so, is there a link to the IES. I've gotten the ones from Lithonia and in the outdoor lighting one, I've been through different categories, but they are mostly cone type lighting. Do they make IES that light i guess you could say, globally or all around or would it be better to just use a Vray sphere.Ive tried the sphere, but its either not bright enough or way to bright. Any thoughts?

Nevermind, It seems once again I have overcomplicated things. Standard omnis with far attenuation do just fine

Remember IES files only exist in order to make it look like there is a fully modeled light fixture. If you do have that post modeled, there's no reason to try IES.

ah I see, Thanks Rick

and in my scenes they take twice longer to render than vray lights or regular max lights. but thye look nice...

i think IES came about as a solution for lighting manufactures to convey information to lighting professionals on how different fixtures and filaments cast light and the intensity of light. so that you can calculate how many fixtures you need in a room to illuminate it. the consultants could put this information into their specialized lighting software to get an accurate idea of what would happen in real life. we are able to utilize the IES files to simulate lighting conditions in real life, though as i understand it, 3dsmax really does a poor job at this compared to the specialized software.

 

the design visualization world in the way we know is an after thought for what this information was designed for in the first place.

 

unless you have something in the model that is in close proximity to the light fixture you are showing i would not bother with IES, as you have already figured out. i don't think the details are noticeable enough for the increased pain in rendering and the extra consideration when creating unless the light is being cast onto something. ....also stated in this thread already.

Thanks Travis for the help

isn't it that IES ligths can proyect patterns on surfaces manily. I beleive it is always a way to make an standard or vrayligth to make such patterns, so, indeed, no need for ies ligths in max & vray.
