Seem to be having issues with mapping of HDR images onto a sphere. I am using YAFRAY in plugin mode (as opposed to XML export). What I am seeing looks like, for lack of a better way of putting it, bunny ears. This is with the St. Peter’s Cross HDR file readily available, but I’ve seen this happen with all of them.
The “ears” seem to be a dark elongated ellipses joined at a common center point radiating outward, and in between the four lobes/ears are what must be the four endpoints of the HDR image. The shadows must correspond to the areas of the HDR file which are black (0,0,0) but divining the solution is the hard part.
I’d love to upload and link the picture but cannot currently do that (while at work -no time, no time, little rest for the wicked). Hopefully for now the description will ring a bell for someone.
The strangest thing, I’ve followed BioRust tut on it, and just cannot get a good render w/o the elongated lobes. Is this an issue with mapping and/or am I neglecting something that should be painfully obvious?
