Quote - Thank you, Morkonan. So are you saying that IDL 2 is older than IBL and not quite as robust as the CVs and Saintfox IBL light sets?

 

No, IDL (Indirect Lighting) is a more recent technology addition to later versions of Poser. IBL (Image Based Lighting) has been around quite awhile.

But, you can get very good results with IBL light sets. You don't need something like IDL2 sets in order to use IDL. Whether or not you can use Indirect Lighting in your renders is dependent on the version of Poser that you have and there's absolutely nothing "special" in regards to IDL lightsets other than the creator has tweaked light settings and reflective surfaces especially for IDL-Capable versions of Poser.

You could, for instance, grab a free IBL based lightset and then add something like BagginsBill's "Environment Sphere" to help out with IDL bounces. You could even use a panaromic image on it to get more accurate lighting, much like the spherized images in IBL lights. (Indirect Light is calculated, in one way, by how the light bounces around the scene. So, if you have a reflective surface, one that can reflect light, then the light bounces of it and gets to illuminate something else before disapating. If you don't have a lot of geometry that light can bounce off of in your scene, using a big sphere to contain your entire scene gives the light something to bounce off of and illuminate the subject, like a figure posed for a portrait.)
