Question about IES lights
Posted: Wed Oct 09, 2019 12:34 am
Hello indigo-community and developers,
after a really long period of absence, I am thinking about coming back to Indigo.
I just played with the current trial-version of indigo. There is a lot happened since version 2!
I remembered this forum as a really helpful and I can see, the old "greybeards" are still on board.
Maybe you guys can help me.
During my tests, I encountered a problem with IES-files. In the renderings, I attached, are 3 different IES-files from iGuzzini (https://www.iguzzini.com/). As you can see, they are all nearly the same width.
But they should have noticeable differences in width.
The two lights on the left (number 1) should be 34cm, the two in the middle (number 2) 64cm and the last two on the right side (number 3) 127cm.
So, what is the problem? Is it a generall problem? Is it possible, the IES-files have problems?
The documentation says, that indigo is capable of "just" rendering IES-files below a vertical angle of 90 degrees (https://www.indigorenderer.com/document ... ies-lights) Could this be a reason?
DonĀ“t get me wrong, I am really impressed with the quality and the fact that it works somehow.
I tested the IES-files with Cinema 4D and they look really wrong.
I would be very happy to have some clarity on this topic because I want to use Indigo for special jobs, there correct lighting is absolutely needed and I see Indigo as the weapon of choice for these jobs.
Thanks in advance,
Carsten
