First a bit of information: I'm better with XSI than I am with Hammer. I have searched for tutorials to no avail. I have XSI 7 with Mod tool plugin and the XSI Mod tool I know XSI can export prefabs. The Questions: What can be brought in from XSI? I heard that there is a way to place but not manipulate entities. Is it possible to create displacements in XSI and bring them in through the prefab?
