The top image is one of the HDRI maps included with Carrara 3; the bottom is a sky map I made in PS for the purpose of a background in Carrara to work as a reflection. It is tileable to the sides, but I am running into a problem with the top and bottom. When it reflects on a sphere, the texture map comes to a point at the top and it is very noticeable. I was wondering if anyone knows how to stretch the top and bottom to the sides to compensate for this effect (I hope you know what I am talking about...I could include some more pictures). Notice how the top and bottom of the HDRI map stretch out so that the map correctly fills the large sphere it is mapped onto with "background." Any help would be appreciated, thanks!
