So I rendered this 360° image
which I plan to use as background and as a HDR light source for upcoming projects. It needs some tweaking, but I have to solve certain problems first that I don't seem to understand.So I used the Vray environment options to set up my scene. The HDR worked fine as GI environment, good light, reflection works fine too. But the image I took for background bothers me. Of course I picked "sphere" for mapping method, which means the image is in a cool way being bent around some kind of virtual sphere with infinite dimensions. That's awesome, but in the rendering, the image seems blurry. Although I used a quite high resolution - 5000x2500px.look at this
I realize the background is quite noisy due to low render settings, same for irradiance map and light cache. Ignore that.
Do you see the blurryness of the background? And the fine sharpness of the "s"? I guess it's because as the background image wraps around the sphere, you're looking at it closer than you actually should. The distance isn't right, but how can I correct this? I think I'm not getting the concept of relativity concerning a rendering inside a rendering.
How do I get a sharp and fine looking background image? Am I going the wrong way here? Wrong workflow? Thanks for your help.
