Problem (IES, Lights)

Post by bahamut » Tue May 22, 2012 12:37 am

Hello everyone.
I'm dumber than I think and for me there is a real problem to do IES Lights in Indigo (I cannot find place where the IES file should be chosen)
And I don't know how to do direct lights like max's standard ones. Do i need to model all lamp including structures or there is another way.

Create a surface ( a single triangle would suffice ). The surface normal should point into the direction you want the light to be emitted in.
Then you can change the material to be an emitting one and there you should be presented with an IES option and should be able to select
A path to your IES file.

What 3d software and exporter are you using ?

3ds max 2011 and latest indigo exporter 3.0.7

Unfortunately i don't see this ies option.

I wanted to do the prism simulation like here: http://upload.wikimedia.org/wikipedia/c ... /Prism.png
and to learn how to control beam of light. In max it's more simple - you have standard spot or direct.

If you're using Maxigo 3.0.7 then you should check out IES Lights page from Maxigo manual.

But now works. It apears that it does not work with some first IES files you have in zip.
