I am new to Carrara and 3D modeling in general. I am working on my first scene in Carrara. I used Anything Grooves to make the spikes on the kiwano melon. It also caused the melon's surface to have a slightly "faceted" appearance. I used a sphere primitive for the melon, not a vertex object sphere. Does anyone have any ideas on what might cause this? On another note, there are also some odd anti-aliasing artifacts around the spikes of the melon. The image I have attached is only part of the scene. Any suggestions would be appreciated.
