I have two HDRI versions
- low res blurry HDRI for diffuse lighting
- high res sharp HDRI for reflections and specs
First solution
Blurry HDRI in my dome light, aligned with sun (for better shadows),
Sharp HDRI in my Environment slot
Then I have to make dome light invisible to render so that sharp background is being rendered, but the reflections are still blurry, I could also uncheck reflection and spec tick box on the Dome light (I am not sure if this is the way to go).
Second solution
I could just use vray's environment switcher rollout in render settings, and after properly aligning sun position with the Dome HDRI just turn this light off and leave it to the switcher.
Third solution
Just use the sharp HDRI for everything.
So again what is the right way to go OR the best way to go?
