Hi Paulo - interreflections are only visible in ratraced viewports. The environment can reflect in Rendered display but to see objects’ reflections, you need to set the viewport to raytraced.
Hi Paolo - you are correct, GP reflections should work - it is object/object reflections that do not. However, it l;ooks to me like there is a bug in the current builds - a straight ‘paint’ or ‘plastic’ mateiral does not show the reflections, you must change the matterail type to ‘Custom’ to get reflections, at least here.
@Paulo_Pugliesi_Filho - from what I can tell so far, the video must be from some older version of Rhino when these Plastic and Paint materials were not ‘PBR’ materials as they are now. RH-77203 Rendered display mode GP reflections
Is that right @Vanessa ?
In the current builds, you must change to a ‘Custom’ material.
