The only one difference between one render and the other is that num 1, is using an HDR file called “013-weg-naast-wei.hdr.001”, 156 Mb and its nodes setup is simpler. While num 2 is using the new HDR addon from BlenderGuru called Pro-Lighting: Skies. Its nodes setup is more complex, which I’m not including here as I’m not sure whether I’d need authorization from Mr Price. The addon is about 30 Mb, so I thought it would lighter to use. The render does take less time. I like the resulting lighting better, except it produces those ugly jaggy shadows. Any idea how to fix this?
