I've been trying to follow the linked tut to use HDRI as a world map, and can't get it to work, any thoughts (blender 2.42a) There are a fair number of comments on the tut that others can't get it to work either, but to me it looks like it should :(----------

It didn't work for me, either... the sphere just reflects the background color of the world and doesn't show the image.
I don't know that much about HDRI in Blender, but I was able to get it work in the Blender internal renderer by changing the world's horizon color to white, and setting the Blend and Paper buttons on the world material. I'm not sure why that makes a difference, though.

Found this fix mentioned at BlenderArtists that seems to make a difference.

Seems to work!, a little error in the mapping, but at least I get an Image :)
Thanks you!

personaly, i never realy liked that tutorial anyway. it doesnt give an example of what HDRI is realy capable of, and doesnt realy explain the settings for HDR maps in blender.
one thing that i have found to help when getting an hdr image is to enable zenup zendown, sometimes hori (horizon) and always blend under the map to tab in the textures box in the world buttons tab.
another usefull thing is to change the colors of the backround. under world buttons--> world, there are two boxes of color, blender's default for these is one dark blue and one black. what i have had much success with is changing the blue box to black and the black box to white.
one other thing that the tutorial doesnt realy explain is which type of texture coordinate to use. for most hdr maps you should use the angle map (angmap). hdr files which use this can be identified by a picture with a fisheye lense sphere in the middle.
