Global Reflection Vs. Reflection Sky Maps

[S. Houtzager]

In the World Info, I am trying to tell the difference between the 2nd tab (global reflection) and the 3rd tab (Raytrace, Reflection Sky Maps). Seems like the two do the same thing.

What I am trying to do is have a global reflection for select objects and not on others. I have turned off global reflections in the material settings for the objects that I don't want a global reflection.

Steven,

You did the right thing for the effect you needed. The global reflection map has a on/off checkbox in the material editor that is not individually available for reflection sky map.

While in some instance both reflection maps seems to do the same thing, the reflection sky map is a different beast. When using raytrace, it will be used only when a ray hits nothing or the end of raytrace recursions is reached. The images can also be of the normal type (LDR) or High Dynamic Range (HDR). You get much more control with Reflection & Refraction Sky Maps.

The way these maps are applied is also different. Please refer to Animator manual on pages 248 to 251 for more info.

I have the feeling I'm missing something, hope someone else chips in...

Both my teapots have Reflection Sky Maps and Global Reflection but only the right one has the checkbox set to use the Global Reflection map.
