HDR & internal yafray exporter

Anyone has an idea on how to use HDR images with yafray using blender internal exporter?
World texture doesn’t accept HDR images, I don’t know where else look…

Here´s a full tut on it, done by block01cube (found it with the search function on ths forum):

Thanks! (I’m sorry I’m a bit late…)

btw next release should integrate it…

by the way. if you get objects to look non grainy with the hdri …please let us know your method. I have only been able to get very reflective materials to look smooth with this method.
