I’m not exactly sure where to post this as the problem is very specific to certain things.
I’m sure everyone is familiar with the game Minecraft and how you can import Minecraft worlds into blender (for use with “Machinimas” and things that cannot be achieved in the actual game). However, most importing tools cannot import “special” blocks such as torches and fences, so, they are replaced with flat planes or some other representation of the object. You will need to replace these objects somehow. Placing them by hand is a terrible way of solving the issue when you have a big area. So how can you replace them automatically? This also goes for things like replacing the leaves on trees and such.
