I DL-ed the latest Terragen beta v0.9 for mac and the free HDRI plugin for it. It saves images to .hdr files so I saw a oppertunity to look at this feature. I rendered the image 1024 x768 and the image was so blurred and zoomed at that camera angle.

I don't know much about HDRI, but I thought that the background should be visable and not only work for reflections.

Should the resolution be very high? Like to know before I test render.
