HDRI lighting trick in Blender Internal


in this thread http://blenderartists.org/forum/showthread.php?t=107208 CyaNn has referred to very smart simulation of HDRI (or to be precise LDRI) lighting in Blender Internal (actually it is fully possible only in Yafray).

I thought it maybe very useful for all Blender users.

Here is the original tutorial in french.

And here is dirt translation by Google transaltor (pictures are quite self-explanatory).

Original author of the tutorial is GFab3D from Blender Clan.

I am also adding example blend file with packed lighting textures - HDRIblend

ok cool the translate.
But image keeped in french.

Personnaly I don’t use LDR but directly HDR. I tweak lightning with the color slider of env map.
