Hi, Everyone~

I'm following a tutorial at http://www.thearchitectureacademy.com/fe/51734-tutorial-simple-lounge-room. It is from Andrew Price of Blenderguru.com. In the video, at approx. 13:10, he sets the background image, an HDRI file, using the "surface" tab in the "world" setting (see image).

The next image is my "world" panel, which has no "surface" tab in the "world" view. Searched the add-ons, Blender wiki for info and I am not having any luck locating this surface tab.I even went so far as downloading 2.67 again to see if possibly the "b" version wouls have this feature. I have checked it in both Edit and Object mode and also checkefd in all the objects in the scene. I have quite a bit of trouble with Andrew and his tutorials because of his accent and the fact that he talks way too fast for an old man like me. I am sure I am just overlooking some vital aspect of this, but will be damned if I can figure it out. I've been at it most of the day and the only progress is a terrific headache. Any help much appreciated!

TIA

Go to the top center of the Blender info bar (top of your Blender window) and switch to the Cycles render engine.  Your surface tab will appear.

Are you just wanting a environmental image for a render or a reference image for constructing models?

@BardicHeart   - thanks so much for your input. It is now as it should be. There was no mention that I am aware of about rendering this in Cycles, but obviously that is the case. I am using an HDRI for environmental lighting. Your input spot on and much appreciated!

No problem.  You can have a lot of fun with the nodes in the Cycles engine to get different effects.  It can be fun just to create a simple scene and play around with it.
