This is a quick render-test with cycles of the scene I was trying to export: 1.2GB size on HD.
I'm a newbye with Blender and I still don't know how to setup correctly the global illumination and hdris.
With Corona I know how to do that in 3DSMAX because I can vary the light of each light including the ambient light from the sun or any light source listed in the lightmixing , in realtime or when the render has ended. This feature has saved me too much time in the past!. :)
