The only difference between these two objects is that one has metallic set to 0 and the other to 1. There is only a skylight in the scene with a cubemap. Put a sphere reflection capture, tried recapturing the scene etc etc.
I was having issues with the skylight not capturing the skysphere material so had to use the cubemap with the HDR in it.
Anyways, can’t seem to get metallic objects to display correctly with the skylight. If I place a point light or spot light, then metallic objects seem to receive light correctly so it appears to be isolated to the skylight.
