He then demonstrated the prefabs, which are basically groups of other placeables and can also consist of placed effects. So a candelabra might actually be composed of many smaller pieces and placed effects of candle flames to give the final effect. What's cool about all these little pieces you get that were used to make bigger things is that they will be very useful separately in other places. He did a quick run through of the placeable list by scrolling with his mouse and it's clear that the list is much bigger than NWN, I'd have to say more than 500 for sure. Also things that were part of the terrain in the first game like houses, are now placeables and can be placed anywhere, which is better in my opinion. Prefabs can also be rotated, resized and tinted as a group, which is helpful.​
