This is perfect for those product shots, easy, fast and looks (usually) good. There are so many ways of positioning lights so just experiment with it but remember that sometimes less is more, and i could make a joke here but let's move on. Vray-RT (vray's realtime renderer) really do shine when it comes to light setups, with it you get realtime feedback on how the illumination looks but most important, how the reflection looks. Getting those nice reflection to look just right can be tricky (luckily i'm a known pro at this...) but with Vray-RT it's so simple. Pro tip incoming - Remember that it's not wrong to also be using a hdri when doing this, trust me, it's sweeter than candy!
