a) uncomment line 50, cloned sphere is now completely dark. Now comment line 46: cloned sphere is now showing the correct lighting. So it was in shadow previously, but where is the shadow coming from ?
b) reset the pg: now uncomment line 48 and 50. Ground and cloned sphere are now completely dark. By previous reasoning, both are in shadow but again where is the shadow coming from that is large enough to cover the ground as well ?
c) And why does the instanced sphere never cast a ashadow on the ground ?
what did I miss or is this wai ?
