Light Probes

Can anyone direct me to a basic level of info on light probes? Either video or written tutorial. Thanks.

I found an old stackexchange post with some info here. And there are several links to Unity related content when searching for "3d what are light probes" on Google.

In Daz Studio, there are products called Light Probe(s). These are HDRI files used in the Render Settings (Environment) and provide high quality light but when Draw Dome is On, the background is simple colors. Here are some promo pictures to show a variety of backgrounds from this kind of lighting:

The above images are from various products by Dimension Theory. Lyoness has a wonderful set of two, Leonine Pro HDRI Lighting, but those products include additional lights, so I didn't include her promos. I have no idea which if any are lit purely by the HDRI.

Then there is Kindred Arts Iray Light Probe Kit, which uses small spheres (probes) throughout a set to add light, using the Ghost Light technique.

If you wanted specific information about light probes, then I doubt if this is very helpful. But if you were wondering why there are both "Light Probes" and "HDRI" products in the store, maybe this will help you understand the difference.

I'm no expert, obviously, but I didn't want you to feel like you were being ignored.

Thanks for the concise explanation, I've wondered about this too.
